CYP75B3 | Flavonoid 3'-monooxygenase CYP75B3; Catalyzes the 3'-hydroxylation of the flavonoid B-ring to the 3',4'-hydroxylated state. Catalyzes the 3'- hydroxylation of apigenin to generate luteolin (Probable). Belongs to the cytochrome P450 family. (526 aa) | ||||
CYP75B4 | Flavonoid 3'-monooxygenase CYP75B4; Catalyzes the 3'-hydroxylation of the flavonoid B-ring to the 3',4'-hydroxylated state. Catalyzes in vitro 3'-hydroxylation of different flavonoids. Catalyzes the conversion of apigenin to luteolin, naringenin to eriodictyol, and kaempferol to quercetin. Possesses specific 5'-hydroxylase activity toward chrysoeriol (a 3'-methoxylated flavone) and is indispensable for tricin formation. Converts chrysoeriol to selgin, a precursor of tricin, suggesting that chrysoeriol, instead of tricetin, is an intermediate in tricin biosynthesis. (535 aa) |
