General description
Lysostaphin is mainly liberated as a proenzyme. It is highly stable at pH 4 and temperature 5°C.
Chemical structure: peptide
Biochem/physiol Actions
Lysostaphin exhibit a lytic action against Staphylococcus aureus. It possesses several functions of three major enzymes, such as, glycylglycine endopeptidase, endo-β-N-acetyl glucosamidase and N-acteyl muramyl-L-alanine amidase. Lysostaphin can be used to treat antibiotic-resistant staphylococcal infections. Lysostaphin being an antistaphylococcal agent, can be used as a preservative in the food industry and in clinical labs for rapid screening.
Lysostaphin is a zinc endopeptidase with a molecular weight of approximately 25 kDa. Because lysostaphin cleaves the polyglycine cross-links in the peptidoglycan layer of the cell wall of Staphylococcus species it has been found useful for cell lysis and also as a potential anti-microbial therapeutic.

Nasal colonization of Staphylococcus aureus (S.aureus) is known as a significant risk factor for nosocomial infections, and clearance of its nasal colonization greatly reduces the risk. In the present study the preparation and characterizations of the chitosan-o/w cream incorporated with
