IntEnz Enzyme Nomenclature
EC 2.3.1.172

Names

Accepted name:
anthocyanin 5-O-glucoside 6'''-O-malonyltransferase
Other name:
Ss5MaT1
Systematic name:
malonyl-CoA:pelargonidin-3-O-(6-caffeoyl-β-D-glucoside)-5-O-β-D-glucoside 6'''-O-malonyltransferase

Reaction

Comments:

Specific for the penultimate step in salvianin biosynthesis. The enzyme also catalyses the malonylation of shisonin to malonylshisonin [cyanidin 3-O-(6''-O-p-coumaryl-β-D-glucoside)-5-(6'''-O-malonyl-β-D-glucoside)]. The compounds 4'''-demalonylsalvianin, salvianin, pelargonidin 3,5-diglucoside and delphinidin 3,5-diglucoside cannot act as substrates.
