2.3.1.213

Accepted name:

cyanidin 3-O-(6-O-glucosyl-2-O-xylosylgalactoside) 6′′′-O-hydroxycinnamoyltransferase

Reaction:

1-O-(4-hydroxycinnamoyl)-β-D-glucose + cyanidin 3-O-(6-O-β-D-glucosyl-2-O-β-D-xylosyl-β-D-galactoside) = β-D-glucose + cyanidin 3-O-[6-O-(6-O-4-hydroxycinnamoyl-β-D-glucosyl)-2-O-β-D-xylosyl-β-D-galactoside]

Glossary:

1-O-(4-hydroxycinnamoyl)-β-D-glucose = 1-O-(4-coumaroyl)-β-D-glucose
cyanidin = 3,3′,4′,5,7-pentahydroxyflavylium

Other name(s):

1-O-(4-hydroxycinnamoyl)-β-D-glucose:cyanidin 3-O-(2"-O-xylosyl-6"-O-glucosylgalactoside) 6′′′-O-(4-hydroxycinnamoyl)transferase

Systematic name:

1-O-(4-hydroxycinnamoyl)-β-D-glucose:cyanidin 3-O-(6-O-β-D-glucosyl-2-O-β-D-xylosyl-β-D-galactoside) 6′′′-O-(4-hydroxycinnamoyl)transferase

Comments:

Isolated from the plant Daucus carota (Afghan cultivar carrot). In addition to 1-O-(4-hydroxycinnamoyl)-β-D-glucose, the enzyme can use the 1-O-sinapoyl- and 1-O-feruloyl- derivatives of β-D-glucose.
