Lysozyme is a naturally occurring enzyme with antibacterial properties, commonly found in various biological fluids such as saliva, tears, and egg whites. It functions by hydrolyzing the -1,4-glycosidic bond between N-acetylglucosamine and N-acetylmuramic acid in bacterial cell walls, leading to the lysis of the bacterial cell. This enzyme is widely used in molecular biology, biochemistry, and microbiology for its ability to break down the peptidoglycan layer of bacterial cell walls, facilitating the extraction of intracellular components, such as nucleic acids and proteins.
Lysozyme is commonly used in research applications to lyse bacterial cells during DNA or protein extraction protocols. It is also used as a preservative in food and pharmaceuticals due to its antimicrobial activity.
