Description

        Lysostaphin (LSS) is a kind of lysozyme secreted by Staphylococcus simulans that specifically dissolves Staphylococcus lysozyme. It was found by Schindler and Schuhard in 1964 from the culture of Staphylococcus simulans. LSS is a zinc containing endonuclease that cleaves the "glycyl pentapeptide" bond of staphylococcus peptidoglycan, causing bacteria to swell, crack and die. For example, it can specifically kill Staphylococcus aureus and Staphylococcus epidermidis, including the cell wall of methicillin resistant Staphylococcus aureus (MRSA) and vancomycin resistant Staphylococcus aureus (VRMA) that can cause fatal infection. The enzyme can also cleave the glycine peptide bond of the cell wall of other gram-positive bacteria, and hydrolyze glycine rich proteins, such as insoluble elastin. This product is a high purity and high activity lysostaphin produced by genetic engineering technology, without animal origin material.
