In enzymology, a flavonol-3-O-glycoside glucosyltransferase ({{EC number|2.4.1.240}}) is an enzyme that catalyzes the chemical reaction

UDP-glucose + a flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucoside UDP + a flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucosyl-(1->2)-beta-D-glucoside

Thus, the two substrates of this enzyme are UDP-glucose and 2)-beta-D-glucoside">flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucoside, whereas its 3 products are UDP, flavonol, and 2)-beta-D-glucosyl-(1->2)-beta-D-glucoside">3-O-beta-D-glucosyl-(1->2)-beta-D-glucosyl-(1->2)-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-beta-D-glucosyl-(1->2)-beta-D-glucoside 2-O-beta-D-glucosyltransferase.
