General description

Estructura química: péptido

Biochem/physiol Actions

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

Una unidad reducirá la turbidez (A620) de una suspensión de células de Staphylococcus aureus de 0,250 a 0,125 en 10 min a un pH 7,5 a 37 °C en 6,0 ml de mezcla de reacción.

WalKR (YycFG) is the only essential two-component regulator in the human pathogen Staphylococcus aureus. WalKR regulates peptidoglycan synthesis, but this function alone does not explain its essentiality. Here, to further understand WalKR function, we investigate a suppressor mutant that arose

Chronic rhinosinusitis (CRS) is a common disease, often refractory to conventional antimicrobial treatment. In this study we investigate the antimicrobial and anti-inflammatory effects of adding kappa-carrageenan to a commercially available sinus rinse. Kappa-carrageenan was added to Flo CRS and Flo

Methicillin-resistant S. aureus has been reported as the main pathogen involved in chronic infections, osteomyelitis, and prosthetic joint infections. The host/pathogen interaction is dynamic and requires several changes to promote bacterial survival. Here, we focused on the internalization and persistence

Lysostaphin (LS), a naturally occurring Staphylococcal endopeptidase, has the ability to penetrate biofilm, and has been identified as a potential antimicrobial to prevent mesh infection. The goals of this study were to determine if LS adhered to porcine mesh (PM)

Background:Staphylococcus aureus (S. aureus) small colony variants (SCVs) can survive within the host intracellular milieu and are associated with chronic relapsing infections. However, it is unknown whether host invasion rates and immune responses differ between SCVs and their wild-type counterparts.
