BRITE hierarchy
Sysname
UDP-alpha-D-glucose:sinapate D-glucosyltransferase
Reaction(IUBMB)
UDP-alpha-D-glucose + sinapate = UDP + 1-O-sinapoyl-beta-D-glucose [RN:R02380]
Reaction(KEGG)
R02380;
(other) R08839
Show
Substrate
UDP-alpha-D-glucose [CPD:C00029];
sinapate [CPD:C00482]
Product
UDP [CPD:C00015];
1-O-sinapoyl-beta-D-glucose [CPD:C01175]
Comment
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-beta-glucosyltransferase).
History
