In enzymology a flavonol-3-O-glucoside glucosyltransferase (EC 2.4.1.239) is an enzyme that catalyzes the chemical reactionUDP-glucose + a flavonol 3-O-beta-D-glucoside UDP + a flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucosideThus the two substrates of this enzyme are UDP-glucose and flavonol 3-O-beta-D-glucoside whereas its two products are UDP and flavonol 3-O-beta-D-glucosyl-(1โ2)-beta-D-glucoside.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
