Accepted name: cyanidin 3-O-glucoside 5-O-glucosyltransferase (acyl-glucose)

Reaction: 1-O-sinapoyl-β-D-glucose + cyanidin 3-O-β-D-glucoside = sinapate + cyanidin 3,5-di-O-β-D-glucoside

Glossary: sinapate = 4-hydroxy-3,5-dimethoxycinnamate
cyanidin = 3,3',4',5,7-pentahydroxyflavylium

Other name(s): AA5GT

Systematic name: 1-O-sinapoyl-β-D-glucose:cyanidin-3-O-β-D-glucoside 5-O-β-D-glucosyltransferase

Comments: Isolated from the plant Dianthus caryophyllus (carnation). Also acts on other anthocyanidins and with other acyl-glucose donors. cf. EC, anthocyanidin 3-O-glucoside 5-O-glucosyltransferase.
