EC 2.3.1.173 Flavonol-3-O-triglucoside O-coumaroyltransferase. [-]    

Pathway: Kaempferol Glycoside Biosynthesis
Reaction: 4-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).
