In Pathway: biochanin A conjugates interconversion

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Mass balance status: Balanced.

Enzyme Commission Primary Name: isoflavone-7-O-β-glucoside 6′′-O-malonyltransferase

Enzyme Commission Synonyms: 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

Standard Gibbs Free Energy (ΔrG in kcal/mol): -1.1135254 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
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.
