Lactoperoxidase
From Proteopedia
Lactoperoxidase (LPO) catalyzes the oxidation of thiocyanate, bromide and iodide using hydrogen peroxide. The short-lived oxidized intermediates of the reaction serve as potent bactericidal agents. LPO is used as an antimicrobial agent in milk and its products, in cosmetics, toothpaste and ophthalmic solutions. LPO is the second most abundant enzyme in milk. Heme is the cofactor of LPO. LPO contains a strongly-chelated calcium ion.
