| Accepted name: |
anthocyanin 5-(6′′′-hydroxycinnamoyltransferase) |
| Reaction: |
4-hydroxycinnamoyl-CoA + an anthocyanidin 3,5-di-O-β-D-glucoside = CoA + anthocyanidin 3-O-β-D-glucoside 5-O-β-D-(6-O-4-hydroxycinnamoylglucoside) |

| Glossary: |
4-hydroxycinnamoyl-CoA = 4-coumaroyl-CoA |
| Systematic name: |
4-hydroxycinnamoyl-CoA:anthocyanidin 3,5-di-O-β-D-glucoside 5-O-glucoside-6′′′-O-4-hydroxycinnamoyltransferase |
| Comments: |
Isolated from the plant Gentiana triflora. Transfers the hydroxycinnamoyl group only to the C-5 glucoside of anthocyanin. Caffeoyl-CoA, but not malonyl-CoA, can substitute as an acyl donor. |
