caffeic acid and esculetin do not react with the enzyme. AtGT-2 prefers flavonene to flavone or flavonol, both of which contain a double bond in the C ring. The relative conversion rate is 100% for eriodictyol, 71.6% for naringenin, 29.6% for apigenin, 92.1% for luteolin, 78.9% for kaempferol and 64.1% for quercetin. |

GmUGT1 is active with UDP-galactose and UDP-glucuronic acid as substrates. It displays high specific activities toward isoflavones (genistein and daidzein) to produce their 7-O-beta-D-glucosides, it also shows considerable levels of activities toward other flavonoids such as kaempferol, quercetin, naringenin and apigenin. GmUGT1 is also capable of acting on the flavone luteolin, (S)-equol, a 4',7-isoflavandiol, and (R)-equol |
