Other name(s): |
uridine diphosphoglucose-isoflavone 7-O-glucosyltransferase; UDPglucose-favonoid 7-O-glucosyltransferase; UDPglucose:isoflavone 7-O-glucosyltransferase |
Systematic name: |
UDP-glucose:isoflavone 7-O-β-D-glucosyltransferase |
Comments: |
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. |
