2-coumarate O-beta-glucosyltransferase () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme characterised from Melilotus alba are o-coumaric acid and UDP-glucose. Its products are melilotoside and uridine diphosphate (UDP).
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:trans-2-hydroxycinnamate O-beta-D-glucosyltransferase. Other names in common use include uridine diphosphoglucose-o-coumarate glucosyltransferase, and UDPG:o-coumaric acid O-glucosyltransferase. This enzyme participates in phenylpropanoid biosynthesis.
