additional information | no activity is observed for dihydroflavonol (dihydroquercetin), isoflavone (genistin, genistein and daidzein), (epi)-flavan-3-O-beta-Dl (catechin, epicatechin), 3-deoxyanthocyanidin (apigeninidin), flavonol conjugate (flavonol 3-O-beta-D-glucosides) and anthocyanins (anthocyanidin 3-O-beta-D-glucosides and cyanidin 3-O-beta-D-galactoside). Galactose can be transferred from UDP-galactose to the 3-position of cyanidin and delphinidin with low specificity relative to the analogous glucosyltransferase reactions | Glycine max | ? | - |
