ABSTRACT:
A microbial method for the preparation of an epothilone containing a terminal hydroxyalkyl group, comprising contacting at least one epothilone having a terminal alkyl group with an enzyme or microorganism capable of catalyzing the selective hydroxylation of said alkyl group to a hydroxyalkyl group, and effecting said hydroxylation.
