摘要

Disclosed is an enzyme having a lignan-hydroxylating activity, particularly an enzyme capable of catalyzing the reaction for transferring a hydroxy group into a lignan, preferably an enzyme capable of catalyzing the hydroxylation reaction from piperitol into 9-hydroxypiperitol or from pinoresinol into 9-hydroxypinoresinol. Specifically disclosed are: a polypeptide having a lignan-hydroxylating activity; a polynucleotide encoding the polypeptide; a vector or transformant carrying the polynucleotide; a method for producing a polypeptide having a lignan-hydroxylating activity by using the transformant; and others. The transformant having the polynucleotide introduced therein in an expressible manner is useful for the hydroxylation of a lignan or the production of a product by using lignan hydroxide in the fields of foods and various industries.
