In enzymology, a monoterpenol O-acetyltransferase () is an enzyme that catalyzes the chemical reaction acetyl-CoA + a monoterpenol CoA + a monoterpenol acetate ester Thus, the two substrates of this enzyme are acetyl-CoA and monoterpenol, whereas its two products are CoA and monoterpenol acetate ester. 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. References EC 2.3.1 Enzymes of unknown structure
