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.
pH de actividad óptimo: ~7,5

Unit Definition

One unit will reduce the turbidity (A620) of a suspension of Staphylococcus aureus cells from 0.250 to 0.125 in 10 min at pH 7.5 at 37 °C in a 6.0 ml reaction mixture.

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

Mesh and wound infections during hernia repair are predominantly caused by Staphylococcus aureus. Human acellular dermis (HAD) is known to lose its integrity in the face of large bacterial loads. The goal of this study was to determine if lysostaphin
