Converting an esterase into an epoxide hydrolase.
Entering the fold: A common structural motif in hydrolytic enzymes is the alpha,beta-hydrolase fold. The interconversion of one enzyme into another by introduction of mechanistically important residues is not enough; only substitution of a loop allows epoxide hydrolase activity in the esterase scaffold to be formed (see picture; structure comparison of epoxide hydrolases (green) with the esterase (orange)). The result is an enantioselective chimeric enzyme.
