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 188.8.131.528, anthocyanidin 3-O-glucoside 5-O-glucosyltransferase.
