LysCSA13
The endolysin Lys from the Staphylococcus aureus virulent bacteriophage CSA13 [1] is composed of two domains that make it capable to lysate the bacteria that are recognized by the enzyme. It keeps its stability in a range of 4 to 37°C and pH from 7 to 9.

Usage and Biology
The endolysin Lys from the Staphylococcus aureus virulent bacteriophage CSA1, is composed of two domains. The bacteriophage CSA13 CHAP domain has excellent catalytic activity, up to 90%, degrading almost 15 strains of Staphylococcus including methicillin-resistant strains (MRSA). As with many of the endolysins, it cleaves to the cell wall by disrupting the peptidoglycan that composes the bacterial cell; for this to be possible, the bacteriophage CSA13 SH3 domain recognizes and binds to the glycine of the pentaglycine cross-bridge glycosidic bond in the heteropolymer of the peptidoglycan, which makes it completely safe for the host [1].
