Lysostaphin Lysostaphin is a 27 kDa-zinc metalloproteinase (EC 3.4.24.75) produced by Staphylococcus simulans. This enzyme hydrolyses glycine/glycine bonds in the pentaglycine interpeptide that maintain the stability of peptidoglycans in staphylococcal cell wall (Surovtsev 1).

Usage

In spite of recent advances in medical care, data reveals that mortality rate among burned patients remains higher depending on the extent of affected area (Pavoni 2). These death rates could also be driven by prolonged antibiotic courses, which related to immunocompetence decrease. Consequently, leading patient to a vulnerability state of the skin to microorganisms (Baker 3), besides the per se lost of the first line of antimicrobial defense. Given the fact that hospital acquired infections is a growing concern in public health alongside the development of resistant strains, burned individuals are at the risk top risk among patients (Leseva 4).

Biology

Lysostaphin is encoded by a three-modular gene that encompasses a self-cleavage peptide, a propetide and the self-coding sequence of lysostaphin. After protein processing, mature lysostaphin (246 aminoacids) is released and exhibits a triple-enzymatic activity: glycylglycine endopeptidase, endo-β-N-acetyl glucosamidase and N-acetyl-muramyl-L-alanine. Consequently, it rapidly lyses actively growing and non-dividing cells including staphylococci in biofilms and, due to its specificity, it could have high potential in the treatment of antibiotic-resistant staphylococcal infections (Kumar 5).
