In enzymology a flavonol-3-O-glycoside xylosyltransferase (EC 2.4.2.35) is an enzyme that catalyzes the chemical reactionUDP-D-xylose + a flavonol 3-O-glycoside UDP + a flavonol 3-[-D-xylosyl-(1->2)-beta-D-glycoside]Thus the two substrates of this enzyme are UDP-D-xylose and flavonol 3-O-glycoside whereas its two products are UDP and [[flavonol 3-[-D-xylosyl-(1->2)-beta-D-glycoside]]].This enzyme belongs to the family of glycosyltransferases specifically the pentosyltransferases.
