    Abstract We synthesized a “cyborg protein,” wherein a synthetic molecule partially substitutes the main peptide chain by linking 2 protein domains with a synthetic oligomer. Green fluorescent protein (GFP) served as the model for constructing the cyborg proteins. We prepared circularly permuted GFP (cpGFP) with new termini between β10 and β11, where the original N- and C-termini were linked by a cleavable peptide loop. The cyborg GFP was constructed from cpGFP by linking the β10 and β11 with oligo(ethylene glycol) (OEG) using maleimide–cysteine couplings, followed by the enzymatic cleavage of the N- and C-termini linking loop by thrombin. With the help of machine learning, we were able to obtain the cpGFP mutants that significantly alter the fluorescence intensity (53% increase) by thrombin treatment, which splits cpGFP into 2 fragments (fragmented GFP), and by heat shock. When the cyborg GFP was constructed using this mutant, the fluorescence intensity increased by 13% after heat treatment, similar to cpGFP (33% increase), and the behavior was significantly different from that of the fragmented GFP. This result suggests the possibility that the OEG chain in the cyborg protein plays a similar role to the peptide in the main chain of the protein.

    More details Close

    Amphiphilic structured PEG derivatives consisting of octa(ethylene glycol) chains connected with aromatic vertices inhibited the thermally-induced lysozyme aggregation even when present at below 0.1 mM concentration. This concentration range is close to a 1:1 molar ratio with the additive and lysozyme, and was completely inaccessible for previously reported stabilizers. The possible mechanisms of the stabilizing actions revealed that the PEG-based amphiphiles do not in fact prevent aggregation at the molecular level, as assumed before, but rather prevent macroscopic precipitation of the denatured protein molecules and enable dissolution of them to the native, folded state at ambient temperature. The stabilizers do not interact with properly folded native lysozyme and therefore do not affect its natural catalytic properties, indicating a potential for practical use in protein-based therapeutics.
