laktoperoxidázový

Laktoperoxidázový refers to lactoperoxidase, an enzyme found in milk and other exocrine secretions. It is a member of the heme peroxidase family and plays a crucial role in the innate immune system. This enzyme catalyzes the oxidation of thiocyanate ions and hydrogen peroxide to produce hypothiocyanite, a potent antimicrobial agent. Hypothiocyanite can disrupt bacterial cell membranes, inhibit enzyme activity, and interfere with essential metabolic processes, thereby preventing the growth of various pathogens. The lactoperoxidase system, which includes lactoperoxidase, thiocyanate, and hydrogen peroxide, is naturally present in the mammary glands of mammals, as well as in saliva and tears. This system contributes to the protection of the oral cavity, mammary gland, and gastrointestinal tract from microbial infections. The activity of lactoperoxidase can be influenced by factors such as pH and the availability of its substrates. Research has explored its potential applications in food preservation and as a therapeutic agent due to its antimicrobial properties.
