In enzymology, a NADPH peroxidase (EC 1.11.1.2) is an enzyme that catalyzes the chemical reaction The 3 substrates of this enzyme are NADPH, H+, and H2O2, whereas its two products are NADP+ and H2O.
This enzyme belongs to the family of oxidoreductases, specifically those acting on a peroxide as acceptor (peroxidases).
The systematic name of this enzyme class is NADPH:hydrogen-peroxide oxidoreductase.
Other names in common use include TPNH peroxidase, NADP peroxidase, nicotinamide adenine dinucleotide phosphate peroxidase, TPN peroxidase, triphosphopyridine nucleotide peroxidase, and NADPH2 peroxidase.
