The improper use of antibiotics in the treatment of bacterial infections has resulted in the appearance of spreading resistant strains [1]. Among them, Staphylococcus aureus has been recognized as an important pathogen both in community-acquired and healthcare-associated infections. S. aureus has successfully become resistant to practically all antibiotics, and this is a serious clinical problem in the world today [2]. Therefore, the search for new pharmaceuticals alternative to antibiotics and design of new treatment approaches of staphylococcal infections are important tasks.

Lysostaphin is a zinc metalloenzyme which has a specific lytic action against S. aureus. Glycylglycine endopeptidase specifically cleaves the glycine–glycine bonds, unique to the interpeptide cross-bridge of the S. aureus cell wall. Due to its unique specificity, lysostaphin could have high potential in the treatment of antibiotic-resistant staphylococcal infections [3].

It is known that lysostaphin...
