Myeloperoxidase (MPO) catalyzes the production of HOCl from hydrogen peroxide and chloride ion during the neutrophil respiratory burst. The hypochlorous acid is used by the neutrophil to kill bacteria and other pathogens. MPO is a dimer consisting of 2 light chains and two variable-length heavy chains. MPO has a heme pigment which causes its green color in secretions like mucus which are rich in neutrophils.
