2.4.1.299

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