Abstract

Heme peroxidase catalyzes the oxidation of a variety of compounds by utilizing hydrogen peroxide. The resting peroxidase reacts with hydrogen peroxide to yield an intermediate compound I, which is reduced to the resting state via the second intermediate compound II, by the use of reducing substrates. The reducing substrates include naturally occurring organic compounds such as phenols and ascorbic acid, diagnostic reagents such as luminol and 4-amino-antipyrine, as well as inorganic compounds such as halide ions, ferrocyanide, and isothiocyanate. Arthromyces peroxidase is a class II peroxidase in the plant peroxidase superfamily, and has the characteristics of giving extraordinarily high chemiluminescence in the oxidation of luminol.
