Flavonol 3-O-glucosyltransferase

In enzymology, a flavonol 3-O-glucosyltransferase (EC number|2.4.1.91) is an enzyme that catalyzes the chemical reaction

:UDP-glucose + a flavonol $ightleftharpoons$ UDP + a flavonol 3-O-beta-D-glucoside

Thus, the two substrates of this enzyme are UDP-glucose and flavonol, whereas its two products are UDP and flavonol 3-O-beta-D-glucoside.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:flavonol 3-O-D-glucosyltransferase. Other names in common use include GTI, uridine diphosphoglucose-flavonol 3-O-glucosyltransferase, UDP-glucose:flavonol 3-O-glucosyltransferase, and UDPG:flavonoid-3-O-glucosyltransferase. This enzyme participates in flavonoid biosynthesis.
