IUBMB Enzyme Nomenclature


Accepted name: alcohol O-cinnamoyltransferase

Reaction: 1-O-trans-cinnamoyl-β-D-glucopyranose + ROH = alkyl cinnamate + glucose

Systematic name: 1-O-trans-cinnamoyl-β-D-glucopyranose:alcohol O-cinnamoyltransferase

Comments: acceptor alcohols (ROH) include methanol, ethanol and propanol. No cofactors are required as 1-O-trans-cinnamoyl-β-D-glucopyranose itself is an "energy-rich" (activated) acyl-donor, comparable to CoA-thioesters. 1-O-trans-Cinnamoyl-β-D-gentobiose can also act as the acyl donor, but with much less affinity.
