cDNA cloning of a BAHD acyltransferase from soybean (Glycine max): Isoflavone 7-O-glucoside-6″-O-malonyltransferase

A cDNA from soybean (Glycine max), GmIF7MaT, was cloned and characterized. The cDNA encoded malonyl-CoA:isoflavone 7-O-glucoside-6″-O-malonyltransferase, which is responsible for the malonylation of isoflavone 7-O-β-d-glucosides to produce the corresponding isoflavone 7-O-(6″-O-malonyl-β-d-glucosides) in G. max. This protein is a member of flavonoid glucoside-specific acyltransferases in the BAHD family.
