Entry

EC 2.4.1.170 Enzyme

Name

isoflavone 7-O-glucosyltransferase;
uridine diphosphoglucose-isoflavone 7-O-glucosyltransferase;
UDPglucose-favonoid 7-O-glucosyltransferase;
UDPglucose:isoflavone 7-O-glucosyltransferase

Class

Transferases;
Glycosyltransferases;
Hexosyltransferases

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)

R07332 > R02932 R06795 R07718 R07720 R07729 R07740 R07753

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.
