BioCyc:RXN-8354

The gene product of UGT73C6 catalyzed the formation of quercetin-3-O-rhamnoside-7-O-gucoside in vitro. This product is also missing from ugt73C6 mutant plants. Therefore, the enzyme is considered aUDP-glucose:flavonol-3-O-glycoside-7-O-glucosyltransferase. 6-hydroxyflavone was a substratein vitro |CITS: [12900416]|, but the activity of this enzyme with 6-hydroxyflavone in planta remains uncertain.

CPD-12575 + CPD-8138 --> CPD-8143 + UDP + PROTON

UDP-glucose[C15H24N2O17P2] + 6-Hydroxyflavone[C15H10O3] = 6-O-β-D-glucosyl-6-hydroxyflavone[C21H20O8] + UDP(3-)[C9H11N2O12P2] + H+[H]
