Descrizione generale
Lactoperoxidase is a major enzyme present in bovine milk and belongs to the peroxidase family. It is present in both plants and animals. The enzyme structure comprises a single polypeptide chain made up of 612 amino acid residues.[1]
Applicazioni
Lactoperoxidase from bovine milk has been used as a standard for milk lactoperoxidase to study the role of H2O2 in the inhibition of Staphylococcus aureus growth by Lactococcus garvieae in the presence of lactoperoxidase in raw milk.[2] It has also been used in lactoperoxidase-mediated iodination to prepare radiolabeled peptides.[3]
Azioni biochim/fisiol
Lactoperoxidase catalyzes the oxidation of iodide to iodine by hydrogen peroxide. This activity provides a gentle, specific alternative to chloramine T for the radioiodination of proteins and DNA.
Lactoperoxidase contributes to the antimicrobial system of milk[2] by inactivating a wide range of micro-organisms. This lactoperoxidase-mediated antimicrobial system is also identified in human secretions such as tear-fluid, saliva, and milk. Lactoperoxidase catalyzes the oxidation of molecules by releasing H2O2. The product exhibits antimicrobial activity.[1]
