Application

Purified extracellular lysostaphin from S. staphylolyticus SAE0091 undergoes strict quality control testing to ensure the absence of detectable levels of contaminating DNA using 35 cycles PCR amplification of 16S and 18S rDNA using universal primer sets.
Lysostaphin is a zinc metalloenzyme isolated from a bacterial culture of Staphylococcus staphylolyticus. It has specific lytic action against other Staphylococcus species, including S. aureus.1,2 Lysostaphin has
hexosaminidase, amidase, and endopeptidase activities. It cleaves polyglycine crosslinks in the cellular wall which leads to cell lysis of Staphylococcus species, but not of other bacterial genera. [Pharmaceuticals 2010, 3(4), 1139-1161]
Lysostaphin is a single polypeptide chain of 246 amino acids, a molecular mass of 26,926 Da, isoelectric point of 9.5, (5) and an activity pH optimum of 7.5.(6)

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.
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.

Physical form

Supplied as a lyophilized powder containing 50–70% protein with the balance primarily as NaCl.

The epidermis is the outermost layer of the skin and the body's primary barrier to external pathogens; however, the early epidermal immune response remains to be mechanistically understood. We show that the chemokine CXCL14, produced by epidermal keratinocytes, exhibits robust

Drivers of pig trucks constitute a potential route of human transmission of livestock-associated methicillin-resistant Staphylococcus aureus clonal complex 398 (LA-MRSA CC398). In this study, we determined MRSA prevalence in pig truck drivers (n = 47) and monitored the nasal microbiota of 9

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.
