    BACKGROUND: Softening of winter-harvested frozen broccoli is a challenge. Application of boron (B) can improve fruit texture, but its effects on processed vegetables remain unexplored. This study is the first to investigate the impact of preharvest B spraying [0 (unsprayed), 195, 390, and 585 mg B L-1] on the firmness and microstructure of frozen broccoli, utilizing different cultivars harvested during the winter season. RESULT: In the unsprayed group, 'Pixel' florets exhibited the highest firmness, followed by 'Ohayo', 'Konnichiwa', and 'Kombanwa', depending on the extent of low-temperature exposure before harvest. Application of B did not enhance the firmness of 'Pixel' or 'Ohayo' florets after freeze-thawing, despite reducing water-soluble pectin levels. Conversely, spraying with 585 mg B L-1 improved the firmness of freeze-thawed 'Konnichiwa' and 'Kombanwa' florets exposed to temperatures < 0 °C before harvesting by improving cell wall integrity via increased sodium carbonate (Na2CO3)-soluble or chelator-soluble pectin. Synchrotron X-ray computed tomography analyses suggested the frozen state has a more ordered cell structure, whereas scanning electron microscopy revealed less cellular structure damage in the thawed state for 'Konnichiwa' florets sprayed with 585 mg B L-1 compared with unsprayed florets. Nevertheless, freeze-thawed 'Konnichiwa' and 'Kombanwa' florets sprayed with 585 mg B L-1 were considerably less firm than unsprayed 'Pixel' or 'Ohayo' florets. CONCLUSION: Preharvest B spraying enhances the firmness of freeze-thawed broccoli grown at low temperatures by increasing cell wall rigidity and minimizing cell structure damage. Nonetheless, B application cannot fully overcome the consequences of exposure to low temperatures before harvest. © 2025 Society of Chemical Industry.

    γ-Secretase is a protease complex embedded in the cell membrane, consisting of the catalytic presenilin subunits (PS1 or PS2) and three additional co-factors: nicastrin, Aph-1, and Pen2. It cleaves the transmembrane domains of type-I transmembrane proteins, such as the amyloid precursor protein (APP) and Notch. The cleavage of APP generates the amyloid β peptides (Aβ), which accumulate in patients with Alzheimer's disease. Despite significant research, the exact mechanism of this unique proteolysis, which occurs within the lipid bilayers, is still not fully understood. To study the enzymatic properties of γ-secretase, we have established a yeast reporter system using artificial γ-secretase substrates containing APP or Notch fragments fused to the transcriptional activator Gal4. The γ-secretase activity was evaluated by transcriptional activation of reporter genes upon Gal4 release from the membrane-bound substrates, as assessed by the growth of yeast or β-galactosidase activity. Furthermore, we have developed an in vitro assay to identify the different forms of Aβ produced from yeast microsomes. These yeast models provide a platform to screen mutations, genes, and compounds that affect γ-secretase function. By studying the loss of function properties of PS1 familial Alzheimer's disease (FAD) mutants, it is possible to screen for FAD suppressor mutations and γ-secretase modulators (GSMs), in addition to γ-secretase inhibitors (GSIs). In this report, we describe the genetic and biochemical methods used to study γ-secretase activity in the yeast system with the essential steps of the protocol for the video.

    Wood ash, a byproduct of woody biomass power generation, has potential as an alternative K fertilizer due to its high K content and pH-raising properties. However, concerns remain about heavy metal contaminants like Cr and the limited understanding of element dynamics in soil–solution–crop systems after wood ash’s application. This study examined the effects of 1% (w/w) wood ash on element dynamics and komatsuna (Brassica rapa var. perviridis) uptake in low-K soil through a pot experiment. XRD was used to analyze mineral composition, SEM-EDS to observe surface and elemental properties, and XANES to examine Cr speciation in wood ash. Soil solution analysis covered macro- and micronutrients, heavy metals, anions, pH, and DOC, while crop element concentrations and aboveground dry weight were also quantified. The chemical speciation of Cu and Cr in a soil solution was modeled using Visual MINTEQ. Wood ash significantly increased K concentrations (from 17 mg/L to 650 mg/L) in the soil solution, along with Ca, Mg, P, and Mo, while reducing Ni, Mn, Zn, and Cd levels. Komatsuna K uptake surged from 123 mg/kg to 559 mg/kg, leading to a 3.31-fold biomass increase. Notably, the Cd concentration in the crops dropped significantly from 0.709 to 0.057 mg/kg, well below the Codex standard of 0.2 mg/kg. Although Cu and Cr concentrations rose in the soil solution, crop uptake remained low due to &gt;99% complexation with fulvic acid, as confirmed by Visual MINTEQ modeling. This study confirms that wood ash is an effective K fertilizer, but emphasizes the need for risk mitigation strategies to ensure safe and sustainable agricultural application.

    Freezing hydrogels can compromise their network structures and modify their properties as a result of ice crystal formation. Therefore, understanding the internal structure, including ice crystals and the state of chemical components within hydrogels, is essential. In this study, we evaluated the elemental distribution in bio-based hydrogels subjected to freezing-thaw process using X-ray absorption spectroscopy with synchrotron radiation. A bio-based hydrogel, prepared from Alaska pollock, underwent both slow and rapid freezing processes. Tomographic images and linear X-ray absorption coefficient distributions of the rapidly frozen hydrogel displayed a uniform image with a mean absorption coefficient of 2.81 cm-1. Conversely, the slowly frozen sample exhibited distinct contrasts with peaks at 2.516 cm-1 (dark) and 3.691 cm-1 (bright), occupying 28% and 72% of the image, respectively. The mean absorption coefficient of the slowly frozen sample was comparable to that of the rapidly frozen sample, indicating no elemental loss. The elements within the hydrogel were categorized into organic elements, macrominerals, and trace elements. The bright areas in the images were attributed to the concentration of macrominerals. Notably, Cl and Na were the primary contributors to the absorption coefficients among the elements present, signifying salt migration during freezing. These findings suggest that the contrast observed in X-ray computed tomography images after freezing reflects the elemental distribution within the hydrogel and successfully demonstrates element localization due to cryoconcentration.

    The emergence of coronavirus disease 2019 (COVID-19) posed a major challenge to healthcare systems worldwide, especially as mutations in the culprit Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) complicated the development of vaccines and antiviral drugs. Therefore, the search for natural products with broad anti-SARS-CoV-2 capabilities is an important option for the prevention and treatment of similar infectious diseases. Lectins, which are widely recognized as antiviral agents, could contribute to the development of anti-SARS-CoV-2 drugs. This study evaluated the binding affinity of six lectins (including the cyanobacterial lectin from Microcystis viridis NIES-102 (MVL), and Jacalin, a lectin from the breadfruit, Artocarpus altilis) to the receptor binding domain (RBD) of the spike protein on the original (wild) SARS-CoV-2 and three of its mutants: Alpha, Delta, and Omicron. MVL and Jacalin showed distinct binding affinity to the RBDs of the four SARS-CoV-2 strains. The remaining four lectins (DB1, ConA, PHA-M and CSL3) showed no such binding affinity. Although the glycan specificities of MVL and Jacalin were different, they showed the same affinity for the spike protein RBDs of the four SARS-CoV-2 strains, in the order of effectiveness Alpha > Delta > original > Omicron. The verification of glycan-specific inhibition revealed that both lectins bind to RBDs by glycan-specific recognition, but, in addition, MVL binds to RBDs through protein-protein interactions.

    A disintegrin and metalloproteinase (ADAM) family proteins are a major class of membrane-anchored multidomain proteinases that are responsible for the shedding of cell surface protein ectodomains, including amyloid precursor protein (APP). Human ADAM 9, 10, and 17 proteolyze APPs and produce non-amyloid-genic p3 peptides, instead of neurotoxic amyloid-β peptides (Aβs; Aβ40 and Aβ42), which form fibrils and accumulate in the brain of patients with Alzheimer’s disease (AD). The ADAM family is closely related to snake venom metalloproteinases (SVMPs), which are derived from ancestral ADAMs but act as soluble proteinases. To test the therapeutic potential of SVMPs, we purified SVMPs from Protobothrops flavoviridis venom using metal ion affinity and pooled into a cocktail. Thus, 9 out of 11 SVMPs in the P. flavoviridis genome were identified in the cocktail. SVMPs inhibited Aβ secretion when added to human cell culture medium without affecting APP proteolysis. SVMPs degraded synthetic Aβ40 and Aβ42 peptides at the same cleavage site (α-site of APP) as ADAM9, 10, and 17. SVMPs did not degrade Aβ fibrils but interfered with their formation, assessed using thioflavin-T. Thus, SVMPs have therapeutic potential for AD as an Aβ-degrading protease, and the finding adds to the discovery of bioactive peptides from venoms as novel therapeutics.

    Amyloid-β peptides (Aβs) are produced via cleavage of the transmembrane region of the amyloid precursor protein (APP) by γ-secretase and are responsible for Alzheimer’s disease. Familial Alzheimer’s disease (FAD) is associated with APP mutations that disrupt the cleavage reaction and increase the production of neurotoxic Aβs, i.e., Aβ42 and Aβ43. Study of the mutations that activate and restore the cleavage of FAD mutants is necessary to understand the mechanism of Aβ production. In this study, using a yeast reconstruction system, we revealed that one of the APP FAD mutations, T714I, severely reduced the cleavage, and identified secondary APP mutations that restored the cleavage of APP T714I. Some mutants were able to modulate Aβ production by changing the proportions of Aβ species when introduced into mammalian cells. Secondary mutations include proline and aspartate residues; proline mutations are thought to act through helical structural destabilization, while aspartate mutations are thought to promote interactions in the substrate binding pocket. Our results elucidate the APP cleavage mechanism and could facilitate drug discovery.

    Aspergillus fungi contain α-1,3-glucan with a low proportion of α-1,4-glucan as a major cell wall polysaccharide. Glycosylphosphatidylinositol (GPI)-anchored α-amylases are conserved in Aspergillus fungi. The GPI-anchored α-amylase AmyD in Aspergillus nidulans has been reported to directly suppress the biosynthesis of cell wall α-1,3-glucan but not to degrade it in vivo. However, the detailed mechanism of cell wall α-1,3-glucan biosynthesis regulation by AmyD remains unclear. Here we focused on AoAgtA, which is encoded by the Aspergillus oryzae agtA gene, an ortholog of the A. nidulans amyD gene. Similar to findings in A. nidulans, agtA overexpression in A. oryzae grown in submerged culture decreased the amount of cell wall α-1,3-glucan and led to the formation of smaller hyphal pellets in comparison with the wild-type strain. We analyzed the enzymatic properties of recombinant (r)AoAgtA produced in Pichia pastoris and found that it degraded soluble starch, but not linear bacterial α-1,3-glucan. Furthermore, rAoAgtA cleaved 3-α-maltotetraosylglucose with a structure similar to the predicted boundary structure between the α-1,3-glucan main chain and a short spacer composed of α-1,4-linked glucose residues in cell wall α-1,3-glucan. Interestingly, rAoAgtA randomly cleaved only the α-1,4-glycosidic bonds of 3-α-maltotetraosylglucose, indicating that AoAgtA may cleave the spacer in cell wall α-1,3-glucan. Consistent with this hypothesis, heterologous overexpression of agtA in A. nidulans decreased the molecular weight of cell wall α-1,3-glucan. These in vitro and in vivo properties of AoAgtA suggest that GPI-anchored α-amylases can degrade the spacer α-1,4-glycosidic linkages in cell wall α-1,3-glucan before its insolubilization, and this spacer cleavage decreases the molecular weight of cell wall α-1,3-glucan in vivo.

    Abstract The aspartate:alanine exchanger family of membrane transporters includes industrially important transporters such as succinate exporter and glutamate exporter. No high-resolution structure is available from this family so far, and the transport mechanism of these transporters also remains unclear. In the present study, we focus on the oligomeric status of the aspartate:alanine antiporter (AspT) of Tetragenococcus halophilus, which is the prototype of this family. To investigate the oligomeric structure of AspT, we established a system that produces high yields of highly purified AspT and determined the oligomeric structure of AspT by analysis with size exclusion chromatography coupled with multi-angle light scattering and blue native PAGE and by comparison of the wild-type AspT with a single-cysteine mutant that forms spontaneous inter-molecular thiol crosslinking. All the results consistently support the notion that AspT is a homodimer in solutions and in membranes.

    Although several reports exist on the use of X-ray analysis in vegetables and fruits to examine internal disorders, cavities, and porosity, information on X-ray analysis of qualities, such as texture, is lacking as well as information on X-ray analysis of legumes. Therefore, this study aimed to perform X-ray analysis with sensory and rheometer tests in cooked vegetable soybean (edamame). Edamame is popular worldwide due to its deliciousness and nutritional value. Vascular structures and cracks around them were clearly visualized using X-ray phase-contrast computed tomography (CT) imaging. In addition, we observed the fine structure of the seed coat, which could be important for seed development, germination, and processing. The density in the edamame beans declined as the boiling time increased, promoting a reduction in hardness described in sensory and rheometer tests. The reduction in density proceeded from the gap between cotyledons, the opposite side of the hypocotyl, and the crack. Collectively, the findings show that the high-resolution X-ray phase-contrast CT imaging conducted in a nondestructive manner may help in effectively evaluating the quality of vegetables and in observing the internal structures related to plant development.

    Amyloid beta peptides (Aβs) are generated from amyloid precursor protein (APP) through multiple cleavage steps mediated by γ-secretase, including endoproteolysis and carboxypeptidase-like trimming. The generation of neurotoxic Aβ42/43 species is enhanced by familial Alzheimer's disease (FAD) mutations within the catalytic subunit of γ-secretase, presenilin 1 (PS1). FAD mutations of PS1 cause partial loss-of-function and decrease the cleavage activity. Activating mutations, which have the opposite effect of FAD mutations, are important for studying Aβ production. Aph1 is a regulatory subunit of γ-secretase; it is presumed to function as a scaffold of the complex. In this study, we identified Aph1 mutations that are active in the absence of nicastrin (NCT) using a yeast γ-secretase assay. We analyzed these Aph1 mutations in the presence of NCT; we found that the L30F/T164A mutation is activating. When introduced in mouse embryonic fibroblasts, the mutation enhanced cleavage. The Aph1 mutants produced more short and long Aβs than did the wild-type Aph1, without an apparent modulatory function. The mutants did not change the amount of γ-secretase complex, suggesting that L30F/T164A enhances catalytic activity. Our results provide insights into the regulatory function of Aph1 in γ-secretase activity.

    Traditionally, filamentous fungi and actinomycetes are well-known cellulolytic microorganisms that have been utilized in the commercial production of cellulase enzyme cocktails for industrial-scale degradation of plant biomass. Noticeably, the Ktedonobacteria lineage (phylum Chloroflexi) with actinomycetes-like morphology was identified and exhibited diverse carbohydrate utilization or degradation abilities. In this study, we performed genome-wide profiling of carbohydrate-active enzymes (CAZymes) in the filamentous Ktedonobacteria lineage. Numerous CAZymes (153-290 CAZymes, representing 63-131 glycoside hydrolases (GHs) per genome), including complex mixtures of endo- and exo-cellulases, were predicted in 15 available Ktedonobacteria genomes. Of note, 4-28 CAZymes were predicted to be extracellular enzymes, whereas 3-29 CAZymes were appended with carbohydrate-binding modules (CBMs) that may promote their binding to insoluble carbohydrate substrates. This number far exceeded other Chloroflexi lineages and were comparable to the cellulolytic actinomycetes. Six multi-modular extracellular GHs were cloned from the thermophilic Thermosporothrix hazakensis SK20-1T strain and heterologously expressed. The putative endo-glucanases of ThazG5-1, ThazG9, and ThazG12 exhibited strong cellulolytic activity, whereas the putative exo-glucanases ThazG6 and ThazG48 formed weak but observable halos on carboxymethyl cellulose plates, indicating their potential biotechnological application. The purified recombinant ThazG12 had near-neutral pH (optimal 6.0), high thermostability (60°C), and broad specificity against soluble and insoluble polysaccharide substrates. It also represented described a novel thermostable bacterial β-1,4-glucanase in the GH12 family. Together, this research revealed the underestimated cellulolytic potential of the Ktedonobacteria lineage and highlighted its potential biotechnological utility as a promising microbial resource for the discovery of industrially useful cellulases.

    Snakebites are one of the major causes of death and long-term disability in the developing countries due to the presence of various bioactive peptides and proteins in snake venom. In Japan, the venom of the habu snake (Protobothrops flavoviridis) causes severe permanent damage due to its myonecrotic toxins. Antivenom immunoglobulins are an effective therapy for snakebites, and antivenom was recently developed with effective suppressive activity against myonecrosis induced by snake venom. To compare the properties of an antivenom having anti-myonecrotic activity with those of conventional antivenom with no anti-myonecrotic activity, this study applied focused proteomics analysis of habu venom proteins using 2D gel electrophoresis. As a target protein for antivenom immunoglobulins with anti-myonecrotic activity, we identified a thrombin-like serine protease, TLSP2 (TLf2), which was an inactive proteolytic isoform due to the replacement of the active site, His43 with Arg. Additionally, we identified the unique properties and a novel synergistic function of pseudoenzyme TLf2 as a myonecrosis-enhancing factor. To our knowledge, this is the first report of a function of a catalytically inactive snake serine protease.

    Abstract A novel series of C12‐keto‐type saxitoxin (STX) derivatives bearing an unusual nonhydrated form of the ketone at C12 has been synthesized, and their NaV‐inhibitory activity has been evaluated in a cell‐based assay as well as whole‐cell patch‐clamp recording. Among these compounds, 11‐benzylidene STX (3 a) showed potent inhibitory activity against neuroblastoma Neuro 2A in both cell‐based and electrophysiological analyses, with EC50 and IC50 values of 8.5 and 30.7 nm, respectively. Interestingly, the compound showed potent inhibitory activity against tetrodotoxin‐resistant subtype of NaV1.5, with an IC50 value of 94.1 nm. Derivatives 3 a–d and 3 f showed low recovery rates from NaV1.2 subtype (ca 45–79 %) compared to natural dcSTX (2), strongly suggesting an irreversible mode of interaction. We propose an interaction model for the C12‐keto derivatives with NaV in which the enone moiety in the STX derivatives 3 works as Michael acceptor for the carboxylate of Asp1717.

    Studies of the structure and function of Carbohydrate-Active enZymes (CAZymes) have made a great deal of progress over the last decade. The glycoside hydrolase (GH) family is a prominent class of CAZymes. There are more than 100 GH families, with wide variations in their 3 D structures (folds). This review focuses on the recently determined crystal structures of 4 GH families: GH42, GH57, GH54 and GH94. Possible evolutionary relationships between apparently unrelated GH families are discussed based on structural and mechanistic similarities.

    The emergence of coronavirus disease 2019 (COVID-19) posed a major challenge to healthcare systems worldwide, especially as mutations in the culprit Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) complicated the development of vaccines and antiviral drugs. Therefore, the search for natural products with broad anti-SARS-CoV-2 capabilities is an important option for the prevention and treatment of similar infectious diseases. Lectins, which are widely recognized as antiviral agents, could contribute to the development of anti-SARS-CoV-2 drugs. This study evaluated the binding affinity of six lectins (including the cyanobacterial lectin from Microcystis viridis NIES-102 (MVL), and Jacalin, a lectin from the breadfruit, Artocarpus altilis) to the receptor binding domain (RBD) of the spike protein on the original (wild) SARS-CoV-2 and three of its mutants: Alpha, Delta, and Omicron. MVL and Jacalin showed distinct binding affinity to the RBDs of the four SARS-CoV-2 strains. The remaining four lectins (DB1, ConA, PHA-M and CSL3) showed no such binding affinity. Although the glycan specificities of MVL and Jacalin were different, they showed the same affinity for the spike protein RBDs of the four SARS-CoV-2 strains, in the order of effectiveness Alpha > Delta > original > Omicron. The verification of glycan-specific inhibition revealed that both lectins bind to RBDs by glycan-specific recognition, but, in addition, MVL binds to RBDs through protein-protein interactions.

    微生物は生育環境中の栄養源、ストレス源などの濃度変化を感知し、増殖や生存のため遺伝子・タンパク質の発現量を増減させる。そのメカニズムを追求していくと、どのタンパク質が関与しているのか?については分かってくる。では、それらのタンパク質はどのように物質濃度を感知しているのか?その感知した情報をどのように発現レベルにつなげているか?発現制御の分子メカニズムは、いわばブラックボックスとなっているものが多く、微生物の応用を妨げる一因ともなっている。このブラックボックスの解明には、タンパク質分子レベルの研究が不可欠である。本研究は、これまでの微生物学を含む農学研究であまり用いられることがなかった放射光の測定技術を積極的に導入し、分子レベルの微生物の発現制御メカニズム解明にアプローチする。そのための研究ターゲットとして、麹菌の4種の転写因子、AmyR、MalR、CreA、FlbCを選び、機能解析、構造解析を目指す。2021年度は、AmyR、MalRについて、機能解析、構造解析を目指して大腸菌による発現系の構築を試みた。大腸菌で発現したAmyR、MalRは封入態を形成し、可溶な状態で獲得ができなかったことから、変性剤の添加による可溶化、ならびに除去によるリフォールディング条件を検討したところ、添加剤存在下で可溶化することが分かった。リフォールディングの条件を検討することで、大腸菌1リットル培養当たり数ミリグラムのタンパク質獲得に成功した。現在、リフォールディング後のタンパク質の機能について解析を進めている。

    We examined the sensitivity of Nav1.1-1.7 to TTX analogues provided by a collaborator and found that 1) chiriquitoxin (CHTX) exhibits low affinity to Nav1.7 due to steric repulsion against isoleucine residues in the TTX binding site, 2) contrary to previous reports, 4,9-anhydroTTX exhibits low affinity to Nav1.6, 3) the deoxy analogues exhibit low affinity to any Nav subtype. We investigated the Nav inhibitory activity of various natural and non-natural TTX and STX derivatives provided by other collaborators and found that the one of the derivatives showed high affinity for Nav1.5, which is normally insensitive to TTX or STX. We found arachidonic acid as an inhibitor of Nav expressed in mouse neuroblastoma Neuro 2A from the marine sponge Halichondria okadai, and investigated the details of the inhibition mechanism.

    The aim of this study was to visualize the dynamics of NO in living cells using sNOOOpy (sensor for NO2/NO3 in physiology), a sensor protein system that detects changes in the concentration of nitrate and nitrite in cells, and to elucidate the physiological dynamics of NO using changes in the concentration of NO3/NO2 as an indicator. The sNOOOpy system was not sensitive enough to detect changes in NO3/NO2 concentration in living cells. In this study, we identified the complex structure of the sNOOOpy system's protein, NasS, with NO3 and NO2, and combined it with protein-level characterization to obtain information on the structural basis at the molecular level.

    It has long been known that bifidobaceria-rich microbiota (bifidus flora) is formed in breast-fed infant intestines; however the underlying mechanism has not been elucidated. We have found that infant gut-associated bifidobacteria have an ability to assimilate human milk oligosaccharides (HMOs) that comprises the third most abundant solid component. In this study, we focused on lacto-N-biosidase, which hydrolyzes lacto-N-tetraose (the most abundant core HMO structure ), and revealed that the enzyme plays an important role in bifidus flora formation in infants. In addition, we succeeded in developing an efficient method to synthesize lacto-N-tetraose by mutating a relevant enzyme. The compound can be used for formula milk fortification.

    Root nodule bacteria control expression levels of protein involved in nitrate assimilation, and the sensing is regulated by protein complex of NasS and NasT. This project tried to reveal nitrate sensing mechanism of NasS-NasT at molecular level, and develop bio-sensor of nitrate in the cells by utilizing NasS-NasT. To clarify structure and function relationships of NasS-NasT, crystallographic approach was attempted. After successful construction of expression and purification system of NasS-NasT, these proteins were subjected to crystallization and X-ray analysis. Finally, novel crystal structure of NasS was solved. In this project, sNOOOpy, sensor for NO3/NO2 in physiology, was developed. This system utilizing NasS-NasT protein enabled us to visualize the changes of nitrate and nitrite level in mammalian cells.

    Breast-fed infant intestines generally have microbiota rich in bifidobacteria, and the population of the bacteria in the ecosystem drastically decreases after weaning. This suggests that human milk has a bifidogenic compound; however, the mechanism underlying it remains elusive. We have reecntly found that infant gut-associated bifidobacteria are equipped with genetic and enzymatic sets dedicated to the utilization of oligosaccharides contained in human milk (human milk oligosaccharides, HMOs). In this study, we aimed to obtain a comprehensive understanding of the HMOs assimilation pathway of bifidobacteria.

    Proteins are altered their structure by phosphorylation, and their functions are changed. Thus, the phosphorylation is key mechanism that involved in regulation of physiological functions. However, relationships between structural-switch and functional-switch by phosphorylation are still unclear. Elucidations of these relationships are expected to facilitate to elucidate mechanisms of phosphrylation-related diseases including cancer. We employed the structural switch of Pin1, that binds to phosphorylated proteins, to develop a novel detection system of phosphorylation-induced structural switch. Characterizations of the Pin1-dirived sensor protein indicated that this sensor protein can detect structural switch of Pin1 induced by phosphorylated sequence.

    Based on the hypothesis that Alzheimer disease is caused by the defect of microtubule polymerization, we have studied the functions of the newly identified the microtubule- regulatory molecules, Pin1 and Gas7b (the proteins consisting of the similar sequence to the WW domain of Pin1). We suggested that Pin1 and Gas7b are useful to the diagnosis and treatment of the age-related diseases. We succeeded in establishing the high throughput screening technology for the low molecular inhibitors of Pin1 and identifying DTM, TME-1 and seaweed polyphenol (974B). We showed that Gas7b accelerates microtubule polymerization by binding phosphorylated tau, regulates neuronal cell morphology by regulating the bundling of microtubules and cross linking of microtubule and actin filament, and exists less level in the brains of patients with Alzheimer disease.

    我々は、リン酸化タンパク質の構造・機能を制御することで様々な生命現象に関わる酵素・Pin1に着目し、細胞中のPin1量を制御することが、タンパク質のリン酸化が引き金となる癌やアルツハイマー病に対する予防・治療へつながると考えている。本研究開発は、Pin1に膜透過性ペプチドを融合した人工タンパク質を開発し、Pin1を細胞内に取り込ませる蛋白質薬剤として応用することを目標としている。本期間(平成23年12月~平成24年7月)では、Pin1に融合する膜透過性ペプチドの検討、「膜透過性ペプチド融合型Pin1」を1グラム合成すること、を最終目標に設定し研究を行った。今後は、タンパク質の大量生産を目指した培養系・精製系の確立を目指す。

    本研究は糖鎖の伸長・分解を触媒する糖質関連酵素についてX線結晶構造解析により反応機構・基質特異性の構造基盤を獲得し、タンパク質工学的手法を用いた有用オリゴ糖合成への応用を目的としている。 ビフィズス菌はラクト-N-ビオース(Ga1-β1,3-GlcNAc)を資化するユニークな代謝経路を持つが、その資化能は加リン酸分解酵素(LNBP)のラクト-N-ビオース分解能に由来する。Bifidobacterium longumのLNBPについて構造解析を行い、基質との複合体構造解析およびドッキングシミュレーションにより反応機構を決定した。LNBPの立体構造は糖質加水分解酵素と類縁の構造を有し、その加リン酸分解は加水分解と類似の機構で進行することが分かった。一方既知の加水分解酵素には見られない特徴として、基質の結合状態によって大きく構造を変化させることを明らかにした。

    糖鎖の伸長、分解に関連する酵素は、アミノ酸配列に基づいて5つの群、100以上のファミリーに分類されているが、多くのファミリー間で立体構造の相同性が見出されている。本研究は、糖質関連酵素の立体構造を解明することで、ファミリー間の構造機能相関を明らかにすることを目的としている。 本年度は、前年度に明らかにした糖質加水分解酵素群ファミリー94(GH-94)に分類される加リン酸分解酵素Vibrio proteolyticus由来キトビオースホスホリラーゼ(ChBP)の立体構造を基に、同じくGH-94に分類される加リン酸分解酵素Cellvibrio gilvus由来セロビオースホスリラーゼ(CgCBP)の構造解析を行った。その結果、CgCBPのグルコース・硫酸複合体構造を2.0Å、グルコース・グリセロール・リン酸複合体構造を2.1Å分解能で明らかにした。後者は、GH-94で初めてのリン酸複合体構造であり、これまで不明だったGH-94のリン酸認識残基を同定した。また、ChBPとCgCBPの構造比較から、両者の基質特異性を決定しているアミノ酸残基を特定した。 CgCBPはGH-94酵素では最も詳細な解析が行われてきた酵素であり、セロビオースや分岐三糖など有用オリゴ糖合成への応用が考案されている。本研究による立体構造の解明により、更なる研究の発展が期待される。 CgCBPの結晶化およびX線回折データ測定の結果は、科学誌Acta Crystallographica Section Dに発表した。またCgCBPの構造解析の結果について、投稿準備中である。
