:UDP-glucose + trans-2-hydroxycinnamate

\rightleftharpoons

UDP + trans-beta-D-glucosyl-2-hydroxycinnamate Thus, the two substrates of this enzyme are UDP-glucose and trans-2-hydroxycinnamate, whereas its two products are UDP and trans-beta-D-glucosyl-2-hydroxycinnamate. 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.
