Protein

Myeloperoxidase

Gene

Mpo

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Part of the host defense system of polymorphonuclear leukocytes. It is responsible for microbicidal activity against a wide range of organisms. In the stimulated PMN, MPO catalyzes the production of hypohalous acids, primarily hypochlorous acid in physiologic situations, and other toxic intermediates that greatly enhance PMN microbicidal activity (By similarity).By similarity

Catalytic activityi

Cl- + H2O2 + H+ = HClO + H2O.
Cl- + H2O2 = HOCl + 2 H2O.

Cofactori

Binds 1 calcium ion per monomer.By similarity
Binds 1 heme B (iron-protoporphyrin IX) group covalently per monomer.By similarity
