Identification
HMDB Protein ID CDBP00276
Secondary Accession Numbers Not Available
Name Myeloperoxidase
Description Not Available
Synonyms
  1. 84 kDa myeloperoxidase
  2. 89 kDa myeloperoxidase
  3. MPO
  4. Myeloperoxidase heavy chain
  5. Myeloperoxidase light chain
Gene Name MPO
Protein Type Enzyme
Biological Properties
General Function Involved in peroxidase activity
Specific Function 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.
