Provided is a technique that can further improve substrate specificity to an L-form during L-menthol and/or L-menthol ester production. A polypeptide that: has A120G, Q88A, Q88G, Q88D, Q88M, Q88L variants of a polypeptide comprising the amino acid sequence represented by sequence no. 1, and in said variants, has a random different moiety other than an amino-acid residue into which a substitution has been introduced; has esterification activity for L-menthol and/or hydrolyzing activity for L-menthol ester, and improves substrate specificity to L-menthol and/or L-menthol ester compared to a polypeptide comprising the amino acid sequence represented by sequence no. 1. During L-menthol and/or L-menthol ester production, the polypeptide can further improve the optical purity of the product.
