General description

Chemical structure: peptide

Biochem/physiol Actions

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.
pH Optimum for activity: ~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.

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

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.

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)
