EC 2.3.1.115     
Accepted name: isoflavone-7-O-β-glucoside 6′′-O-malonyltransferase
Reaction: malonyl-CoA + biochanin A 7-O-β-D-glucoside = CoA + biochanin A 7-O-(6-O-malonyl-β-D-glucoside)

Other name(s): flavone/flavonol 7-O-β-D-glucoside malonyltransferase; flavone (flavonol) 7-O-glycoside malonyltransferase; malonyl-CoA:flavone/flavonol 7-O-glucoside malonyltransferase; MAT-7; malonyl-coenzyme A:isoflavone 7-O-glucoside-6′′-malonyltransferase; malonyl-coenzyme A:flavone/flavonol-7-O-glycoside malonyltransferase
Systematic name: malonyl-CoA:isoflavone-7-O-β-D-glucoside 6′′-O-malonyltransferase
Comments: 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.
