| Other name(s): |
UDP-glucose-apigenin β-glucosyltransferase; UDP-glucose-luteolin β-D-glucosyltransferase; uridine diphosphoglucose-luteolin glucosyltransferase; uridine diphosphoglucose-apigenin 7-O-glucosyltransferase; UDP-glucosyltransferase (ambiguous) |
| Systematic name: |
UDP-glucose:5,7,3′,4′-tetrahydroxyflavone 7-O-β-D-glucosyltransferase |
| Comments: |
A number of flavones, flavanones and flavonols can function as acceptors. Different from EC 2.4.1.91 (flavonol 3-O-glucosyltransferase). |
