In enzymology, an alcohol O-cinnamoyltransferase () is an enzyme that catalyzes the chemical reaction 1-O-trans-cinnamoyl-beta-D-glucopyranose + ROH alkyl cinnamate + glucose Thus, the two substrates of this enzyme are 1-O-trans-cinnamoyl-beta-D-glucopyranose and an alkanol (ROH), whereas its two products are alkyl cinnamate and glucose. 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 1-O-trans-cinnamoyl-beta-D-glucopyranose:alcohol O-cinnamoyltransferase. References EC 2.3.1 Enzymes of unknown structure
