a monoterpenol +acetyl-CoA a monoterpenol acetate ester + CoA

Menthol is a typical substrate of the enzyme characterised from peppermint and is converted to menthyl acetate:

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:monoterpenol O-acetyltransferase. This enzyme is also called menthol transacetylase.
