Accepted name: hydroxycinnamate 4-β-glucosyltransferase
Reaction: UDP-glucose + trans-4-hydroxycinnamate = UDP + 4-O-β-D-glucosyl-4-hydroxycinnamate
Other name(s): uridine diphosphoglucose-hydroxycinnamate glucosyltransferase; UDP-glucose-hydroxycinnamate glucosyltransferase; hydroxycinnamoyl glucosyltransferase
Systematic name: UDP-glucose:trans-4-hydroxycinnamate 4-O-β-D-glucosyltransferase
Comments: Acts on 4-coumarate, ferulate, caffeate and sinapate, forming a mixture of 4-glucosides and glucose esters (cf. EC sinapate 1-glucosyltransferase).
