Pyridoxine 5’-phosphate oxidase (PPO) catalyzes the oxidation of pyridoxamine-phosphate by molecular oxygen producing pyridoxal 5’-phosphate, ammonia and hydrogen peroxide. pyridoxal 5’-phosphate (PLP), commonly known as vitamin B6, which is a biological essential cofactor. PPO catalyzes the last step in vitamin B6 metabolism. PPO uses FMN as cofactor.
