Hydroxycinnamate 4-beta-glucosyltransferase () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme characterised from tomato are p-coumaric acid and UDP-glucose. Its products are p-coumaric acid glucoside 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-4-hydroxycinnamate 4-O-beta-D-glucosyltransferase. Other names in common use include uridine diphosphoglucose-hydroxycinnamate glucosyltransferase, UDP-glucose-hydroxycinnamate glucosyltransferase, and hydroxycinnamoyl glucosyltransferase.
