physiological function the enzyme is involved in antioxidant and redox regulation, overview. The protein catalyzes a complex reaction, with the safe reduction of molecular oxygen into water, without the release of reactive oxygen species, like hydrogen peroxide, superoxide anion, which result from partial O2 reduction Solanum lycopersicum
