Description

General description

Chemical structure: peptide

Package size based on protein content

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

Physical form

Contains potassium phosphate buffer salts and sodium chloride

Preparation Note

Affinity purified

Other Notes

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.
