Sinapate 1-glucosyltransferase

In enzymology, a sinapate 1-glucosyltransferase (EC 2.4.1.120) is an enzyme that catalyzes the chemical reaction:

UDP-glucose + sinapate ${\displaystyle \rightleftharpoons }$ UDP + 1-sinapoyl-D-glucose

Thus, the two substrates of this enzyme are UDP-glucose and sinapate, whereas its two products are UDP and 1-sinapoyl-D-glucose.

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. This enzyme participates in phenylpropanoid biosynthesis.
