EC 2.4.1.177     
Accepted name: cinnamate β-D-glucosyltransferase
Reaction: UDP-glucose + trans-cinnamate = UDP + trans-cinnamoyl β-D-glucoside
Other name(s): uridine diphosphoglucose-cinnamate glucosyltransferase; UDPG:t-cinnamate glucosyltransferase
Systematic name: UDP-glucose:trans-cinnamate β-D-glucosyltransferase
Comments: 4-Coumarate, 2-coumarate, benzoate, feruloate and caffeate can also act as acceptors, but more slowly. Involved in the biosynthesis of chlorogenic acid in the root of the sweet potato, Ipomoea batatas.
