The microsomal epoxide hydrolase gene (referred to as mMCEH) of Mugil cephalus was cloned by PCR, and then inserted to pColdI and pET-21b(+) vector, respectively. The recombinant E. coli possessing the recombinant plasmids exhibited the enantioperference toward (R)-styrene oxide. When enantioselective kinetic resolutions were conducted with 20 mM racemic styrene oxide, enantiopure (S)-styrene oxide was obtained with high enantiopurity more than 99% enantiomeric excess (ee) and 24.50% yield by using the recombinant E. coli harboring pET-21b(+)/mMCEH.
