In [[enzymology]], a '''flavonol-3-O-triglucoside O-coumaroyltransferase''' ({{EC number|2.3.1.173}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:4-coumaroyl-CoA + a flavonol 3-O-[beta-D-glucosyl-(1->2)-beta-D-glucosyl-(1->2)-beta-D-glucoside] <math>\rightleftharpoons</math> CoA + a flavonol 3-O-[6-(4-coumaroyl)-beta-D-glucosyl-(1->2)-beta-D-glucosyl-(1->2)- beta-D-glucoside]

The 3 [[substrate (biochemistry)|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 [[product (chemistry)|products]] are [[coenzyme A|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 [[transferase]]s, to be specific those [[acyltransferase]]s transferring groups other than aminoacyl groups.  The [[List of enzymes|systematic name]] of this enzyme class is '''4-coumaroyl-CoA:flavonol-3-O-[beta-D-glucosyl-(1->2)-beta-D-glucosid e] 6'''-O-4-coumaroyltransferase.
