Accepted name: sinapate 1-glucosyltransferase
Reaction: UDP-α-D-glucose + sinapate = UDP + 1-O-sinapoyl-β-D-glucose
Glossary: sinapate = (2E)-3-(4-hydroxy-3,5-dimethoxyphenyl)prop-2-enoate
Other name(s): uridine diphosphoglucose-sinapate glucosyltransferase; UDP-glucose:sinapic acid glucosyltransferase; uridine 5′-diphosphoglucose-hydroxycinnamic acid acylglucosyltransferase; UDP-glucose:sinapate D-glucosyltransferase
Systematic name: UDP-α-D-glucose:sinapate D-glucosyltransferase
Comments: Some other hydroxycinnamates, including 4-coumarate, ferulate and caffeate, can act as acceptors, but more slowly. Only glucose esters, not glucosides, are formed (cf. EC hydroxycinnamate 4-β-glucosyltransferase).
