In enzymology a flavonol-3-O-glucoside L-rhamnosyltransferase (EC 2.4.1.159) is an enzyme that catalyzes the chemical reactionUDP-L-rhamnose + a flavonol 3-O-D-glucoside UDP + a flavonol 3-O-[beta-L-rhamnosyl-(1->6)-beta-D-glucoside]Thus the two substrates of this enzyme are UDP-L-rhamnose and flavonol 3-O-D-glucoside whereas its two products are UDP and [[flavonol 3-O-[beta-L-rhamnosyl-(1->6)-beta-D-glucoside]]].This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
