In enzymology, a flavonol-3-O-triglucoside O-coumaroyltransferase (EC 2.3.1.173) is an enzyme that 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]\displaystyle{ \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 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. The 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.
