Accepted name: |
flavonol-3-O-triglucoside O-coumaroyltransferase |
Reaction: |
4-coumaroyl-CoA + a flavonol 3-O-[β-D-glucosyl-(1→2)-β-D-glucosyl-(1→2)-β-D-glucoside] = CoA + a flavonol 3-O-[6-(4-coumaroyl)-β-D-glucosyl-(1→2)-β-D-glucosyl-(1→2)-β-D-glucoside] |

Other name(s): |
4-coumaroyl-CoA:flavonol-3-O-[β-D-glucosyl-(1→2)-β-D-glucoside] 6′′′-O-4-coumaroyltransferase (incorrect) |
Systematic name: |
4-coumaroyl-CoA:flavonol 3-O-[β-D-glucosyl-(1→2)-β-D-glucosyl-(1→2)-β-D-glucoside] 6′′′-O-4-coumaroyltransferase |
Comments: |
Acylates kaempferol 3-O-triglucoside on the terminal glucosyl unit, almost certainly at C-6. |
