IntEnz Enzyme Nomenclature


Accepted name:
isoflavone-7-O-β-glucoside 6''-O-malonyltransferase
Other names:
flavone (flavonol) 7-O-glycoside malonyltransferase
flavone/flavonol 7-O-β-D-glucoside malonyltransferase
malonyl-CoA:flavone/flavonol 7-O-glucoside malonyltransferase
malonyl-coenzyme A:flavone/flavonol-7-O-glycoside malonyltransferase
malonyl-coenzyme A:isoflavone 7-O-glucoside-6''-malonyltransferase
Systematic name:
malonyl-CoA:isoflavone-7-O-β-D-glucoside 6''-O-malonyltransferase



The 6-position of the glucose residue of formononetin can also act as acceptor; some other 7-O-glucosides of isoflavones, flavones and flavonols can also act, but more slowly.
