The functional repurposing of structural proteins offers exciting opportunities for sustainable and efficient biocatalysis. This study presents the engineering of two structural proteins, F-actin, to exhibit nitrilase activity, enabling the conversion of 1-(cyanomethyl)cyclohexane-1-carbonitrile into 2-(1-cyanocyclohexyl)acetic acid, a key intermediate in the production of gabapentin. By introducing catalytic residues adapted from nitrilase enzymes, these engineered proteins...
