ID 2.3.1.115 DE isoflavone-7-O-beta-glucoside 6''-O-malonyltransferase. AN flavone/flavonol 7-O-beta-D-glucoside malonyltransferase. CA biochanin A 7-O-beta-D-glucoside + malonyl-CoA = biochanin A 7-O-beta-D- CA glucoside 6''-O-malonate + CoA. CC -!- The 6-position of the glucose residue of formononetin can also act as CC acceptor; some other 7-O-glucosides of isoflavones, flavones and CC flavonols can also act, but more slowly. //
