Abstract

The present invention relates to a composition having the activity of degrading the cell wall of a Mycobacterium species comprising: (a) a first fusion protein comprising (i) a first endolysin or a first domain, both having a first enzymatic activity; (ii) at least one peptide stretch fused to the N- or C-terminus of the endolysin having the first enzymatic activity or the domain having the first enzymatic activity, wherein the peptide stretch is selected from the group consisting of synthetic amphipathic peptide, synthetic cationic peptide, synthetic polycationic peptide, synthetic hydrophobic peptide, synthetic antimicrobial peptide (AMP) or naturally occurring AMP; and (iii) a protein transduction domain (PTD) being at the N- or C-terminus of the first fusion protein, wherein the PTD is having the characteristic to deliver a cargo from the extracellular to the intracellular space of a cell; and (b) a second fusion protein comprising (i) a second endolysin or a second domain, both having a second enzymatic activity; (ii) at least one peptide stretch fused to the N- or C-terminus of the endolysin having a second enzymatic activity or the domain having the second enzymatic activity, wherein the peptide stretch is selected from the group consisting of synthetic amphipathic peptide, synthetic cationic peptide, synthetic polycationic peptide, synthetic hydrophobic peptide, synthetic antimicrobial peptide (AMP) or naturally occurring AMP; and (iii) a protein transduction domain (PTD) being at the N- or C-terminus of the second fusion protein, wherein the PTD is having the characteristic to deliver a cargo from the extracellular to the intracellular space of a cell. Moreover, the present invention relates in particular to said composition for use as a medicament, a disinfectant, a feed additive, or a food additive as well as the use of said composition in the treatment or prevention of diseases caused by an infection with a Mycobacterium species.
