Abstract
An isolated esterase gene coding for an esterase capable of causing asymmetric hydrolysis of an organic carboxylic acid ester of a cyclopentenolone of formula I: wherein R1 is C1-C10 alkyl, C2-C10 alkenyl, C2-C10 alkynyl or C1-C4 haloalky, to produce the cyclopentenolone of formula I in (S)-form, and hybridizing to the base sequence of SEQ ID NO:1, is useful for the industrially favorable production of optically active cyclopentenolones of formula I which serve as the intermediates of drugs, agricultural chemicals or other active products.
