2.4.1.120 |
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 2.4.1.126 hydroxycinnamate 4-β-glucosyltransferase). |
