Introduction The discovery of antibiotics was a milestone in medicine. Lysostaphin (EC 3.4.24.75, glycyl-glycine endopeptidase) is a Staphylococcus simulans metalloendopeptidase (crystal structure of lysostaphin). It can function as a bacteriocin (antimicrobial) against Staphylococcus aureus. Lysostaphin is a 27 KDa glycylglycine endopeptidase, an antibacterial enzyme which is capable of cleaving the crosslinking pentaglycine bridges found in the cell wall peptidoglycan of certain Stap…
