In enzymology a flavonol-3-O-triglucoside O-coumaroyltransferase (EC 2.3.1.173) is an enzyme that catalyzes the chemical reaction4-coumaroyl-CoA + a flavonol 3-O-[beta-D-glucosyl-(1->2)-beta-D-glucosyl-(1->2)-beta-D-glucoside] CoA + a flavonol 3-O-[6-(4-coumaroyl)-beta-D-glucosyl-(1->2)-beta-D-glucosyl-(1->2)- beta-D-glucoside]The 3 substrates of this enzyme are 4-coumaroyl-CoA flavonol and [[3-O-beta-D-glucosyl-(1->2)-beta-D-glucosyl-(1->2)-beta-D-glucoside]] whereas its 4 products are CoA flavonol [[3-O-[6-(4-coumaroyl)-beta-D-glucosyl-(1->2)-beta-D-glucosyl-(1->2)-]] and beta-D-glucoside].This enzyme belongs to the family of transferases to be specific those acyltransferases transferring groups other than aminoacyl groups.
