Bacteriophages encode endolysins to lyse their host cell and allow escape of their progeny. Endolysins are also active against Gram-positive bacteria when applied from the outside and are thus attractive anti-bacterial agents. LysK, an endolysin from staphylococcal phage K, contains an N-terminal cysteine-histidine dependent amido-hydrolase/peptidase domain (CHAP(K)), a central amidase domain and a C-terminal SH3b cell wall-binding domain. CHAP(K) cleaves bacterial peptidoglycan between the tetra-peptide stem and the penta-glycine bridge.
