General description
Chemical structure: peptide
Lysostaphin is mainly liberated as a proenzyme. It is highly stable at pH 4 and temperature 5°C.
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.
La lisostafina es una endopeptidasa de cinc con un peso molecular de aproximadamente 25 kDa. Debido a que la lisostafina rompe los enlaces transversales de la poliglicina de la capa de peptidoglucanos de la pared celular de las especies de Staphylococcus , se ha encontrado útil para la lisis celular y también como potencial tratamiento antimicrobiano.

Resistance to lysostaphin, a staphylolytic glycylglycine endopeptidase, is due to a FemABX-like immunity protein that inserts serines in place of some glycines in peptidoglycan cross bridges. These modifications inhibit both binding of the recombinant cell wall targeting domain and catalysis
