Fig. 3From: Rational protein engineering of a ketoacids decarboxylase for efficient production of 1,2,4-butanetriol from arabinoseRepresentation of the catalytic pocket of KivD generated by molecular docking models. His112 and His113 are the two active-site residues of KivD. The binding site of KivD is delineated by amino acid residues V461, I465, S286 and F542 in conjunction with the cofactor thiamin diphosphate (TPP)Back to article page
