Lactoperoxidase is a peroxidase enzyme secreted from mammary salivary and other mucosal glands that functions as a natural antibacterial agent. Lactoperoxidase is a member of the heme peroxidase family of enzymes. In humans lactoperoxidase is encoded by the LPO gene.Lactoperoxidase catalyzes the oxidation of a number of inorganic and organic substrates by hydrogen peroxide. These substrates include bromide and iodide and therefore lactoperoxidase can be categorised as a haloperoxidase.
