1-O-sinapoyl-β-D-glucose

The two substrates of this enzyme characterised from radish are sinapinic acid and UDP-glucose. Its products are 1-O-sinapoyl-β-D-glucose and uridine diphosphate (UDP).[1]

The product is an intermediate in the biosynthesis of sinapine.[2][3]

Sinapine

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:sinapate D-glucosyltransferase. Other names in common use include uridine diphosphoglucose-sinapate glucosyltransferase, UDP-glucose:sinapic acid glucosyltransferase, uridine 5'-diphosphoglucose-hydroxycinnamic acid, and acylglucosyltransferase.[4]
