In enzymology, a flavonol 7-O-beta-glucosyltransferase (EC 2.4.1.237) is an enzyme that catalyzes the chemical reaction

UDP-glucose + a flavonol $\rightleftharpoons$ UDP + a flavonol 7-O-beta-D-glucoside

Thus, the two substrates of this enzyme are UDP-glucose and flavonol, whereas its two products are UDP and flavonol 7-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 7-O-beta-D-glucosyltransferase. This enzyme is also called UDP-glucose:flavonol 7-O-glucosyltransferase.
