BRITE hierarchy
Sysname
UDP-glucose:isoflavone 7-O-beta-D-glucosyltransferase
Reaction(IUBMB)
UDP-glucose + an isoflavone = UDP + an isoflavone 7-O-beta-D-glucoside [RN:R07332]
Reaction(KEGG)
Substrate
UDP-glucose [CPD:C00029];
isoflavone [CPD:C00799]
Product
UDP [CPD:C00015];
isoflavone 7-O-beta-D-glucoside [CPD:C04074]
Comment
The 4'-methoxy isoflavones biochanin A and formononetin and, more slowly, the 4'-hydroxyisoflavones genistein and daidzein, can act as acceptors. The enzyme does not act on isoflavanones, flavones, flavanones, flavanols or coumarins.
