Transferring groups other than aminoacyl groups
BRITE hierarchy
Sysname
malonyl-CoA:isoflavone-7-O-beta-D-glucoside 6''-O-malonyltransferase
Reaction(IUBMB)
malonyl-CoA + biochanin A 7-O-beta-D-glucoside = CoA + biochanin A 7-O-(6-O-malonyl-beta-D-glucoside) [RN:R06796]
Reaction(KEGG)
Substrate
malonyl-CoA [CPD:C00083];
biochanin A 7-O-beta-D-glucoside [CPD:C05376]
Product
CoA [CPD:C00010];
biochanin A 7-O-(6-O-malonyl-beta-D-glucoside) [CPD:C12625]
Comment
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.
