  • Abstract Esterases, enzymes that hydrolyze ester bonds, have been utilized to synthesize optically pure compounds like (S)-ketoprofen, which can be produced by the esterase-catalyzed hydrolysis of rac -ketoprofen ethyl ester. We previously reported a novel esterase, Est25, which was expressed in active form in Escherichia coli , and showed high hydrolyzing activities for various substrates. However, the enzyme did not show any preference for either of rac -ketoprofen ethyl ester. In this study… CONTINUE READING
