EC 2.3.1.215

Accepted name: anthocyanidin 3-O-glucoside 6''-O-acyltransferase

Reaction: 4-hydroxycinnamoyl-CoA + an anthocyanidin 3-O-β-D-glucoside = CoA + an anthocyanidin 3-O-[6-O-(4-hydroxycinnamoyl)-β-D-glucoside]

Glossary: 4-hydroxycinnamoyl-CoA = 4-coumaroyl-CoA
3,4-dihydroxycinnamoyl-CoA = caffeoyl-CoA
cyanidin = 3,3',4',5,7-pentahydroxyflavylium
delphinidin = 3,3',4',5,5',7-hexahydroxyflavylium

Systematic name: 4-hydroxycinnamoyl-CoA:anthocyanin-3-O-glucoside 6''-O-acyltransferase

Comments: Isolated from the plants Perilla frutescens and Gentiana triflora (clustered gentian). Acts on a range of anthocyanidin 3-O-glucosides, 3,5-di-O-glucosides and cyanidin 3-rutinoside. It did not act on delphinidin 3,3',7-tri-O-glucoside. Recombinant Perilla frutescens enzyme could utilize caffeoyl-CoA but not malonyl-CoA as alternative acyl donor.
