Reaction: UDP-glucose + trans-2-hydroxycinnamate = UDP + trans-β-D-glucosyl-2-hydroxycinnamate
Other name(s): uridine diphosphoglucose-o-coumarate glucosyltransferase; UDPG:o-coumaric acid O-glucosyltransferase
Systematic name: UDP-glucose:trans-2-hydroxycinnamate O-β-D-glucosyltransferase
Comments: Coumarinate (cis-2-hydroxycinnamate) does not act as acceptor.
