the process of inactivation is impeded by the addition of inhibitors of myeloperoxidase ( kcn , nan3 ) , of catalase , of methionine but not by the addition of superoxide dismutase , indicating that the mechanism of inactivation is the oxidation of methionine residue by myeloperoxidase-h2o2-halide system .
