摘要：
The present invention relates to a DNA fragment containing a nucleotide sequence that encodes an amino acid sequence of esterase, said esterase asymmetrically hydrolyzing carboxylic acid esters represented by the formula (I); ##STR1## (wherein R.sub.1 is alkyl, aralkyl or aryl, R.sub.2 and R.sub.3 are alkyl, and n is 1 or 2) an esterase encoded by the DNA fragment, a recombinant plasmid containing the DNA fragment, a microorganism transformed with the recombinant plasmid and methods of producing optically active carboxylic acids and their enantiomeric esters.
