一般描述
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.
应用
Lactoperoxidase from bovine milk has been used as a standard for milk lactoperoxidase to study the role of H2O2in the inhibition ofStaphylococcus aureusgrowth byLactococcus garvieaein the presence of lactoperoxidase in raw milk. It has also been used in lactoperoxidase-mediated iodination to prepare radiolabeled peptides.
包装
1, 5 mg in glass bottle
10, 25 mg in poly bottle
生化/生理作用
Lactoperoxidase contributes to the antimicrobial system of milk 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.
