Myeloperoxidase catalyses the conversion of H2O2 and Cl- to hypochlorous acid (HOCl). It also reacts with O2- to form the oxy adduct (compound III). To determine how O2- affects the formation of HOCl, chlorination of monochlorodimedon by myeloperoxidase was investigated

Biochimica et biophysica acta, 957(2), 185-191 (1988-11-23)
Chlorination of monochlorodimedon is routinely used to measure the production of hypochlorous acid catalysed by myeloperoxidase from H2O2 and Cl-. We have found that the myeloperoxidase/H2O2/Cl- system, at pH 7.8, catalysed the loss of monochlorodimedon with a rapid burst phase

Chloroperoxidase (CPO) from Caldariomyces fumago was optimally covalently immobilized on chitosan membranes pretreated with 0.8 M glutaraldehyde at pH 3.5 to give 3.18 mg CPO g(-1) support. Using monochlorodimedone (MCD) as assay substrate, the immobilized-CPO retained 40% activity at 50

The kinetics of chloroperoxidase-catalyzed bromination and chlorination reactions were studied at various halide and hydrogen peroxide concentrations. At very high concentrations, both chloride (KI = 370 mM) and bromide (KI = 150 mM) are competitive substrate inhibitors versus hydrogen peroxide.

Stimulated neutrophils discharge large quantities of superoxide (O2.-), which dismutates to form H2O2. In combination with Cl-, H2O2 is converted into the potent oxidant hypochlorous acid (HOCl) by the haem enzyme myeloperoxidase. We have used an H2O2 electrode to monitor
