Method of proteolysis, peptidase, a composition for use as a bactericide or bacteriostatic agent, a kit and the use of an active form of S. aureus LytM or a derivative thereof

摘要

The invention relates to new method of peptide hydrolysis, in particular of the cell walls of Gram-positive bacteria, wherein the active form of LytM or derivative thereof is contacted with a peptide substrate, preferably with the cell walls of Gram-positive bacteria, in an aqueous environment of conductivity lower than 10 mS/cm. The invention also relates to composition comprising active form of LytM or derivative thereof and new uses of active form of LytM or derivative thereof.
