Catalytic Mechanism of Myeloperoxidase & Hypochlorous Acid Functions

The video tutorial explains the enzyme myeloperoxidase, its mechanism, and its role in the immune system. Myeloperoxidase, expressed by neutrophils, generates hypochlorous acid, a reactive oxidative species used to oxidize proteins of invading pathogens. The mechanism involves a heme moiety and hydrogen peroxide, leading to the formation of hypochlorous acid, which damages proteins by oxidizing cysteine residues. The video also covers the generation of hypothyroid cyanide, another reactive species, and its impact on proteins.
