Abstract

The application relates to antimicrobial agents against Gram-negative bacteria, in particular to fusion proteins composed of an enzyme having the activity of degrading the cell wall of Gram-negative bacteria and a peptide stretch fused to the enzyme at the N- or C-terminus, as well as pharmaceutical compositions thereof. Moreover, it relates to nucleic acid molecules encoding such a fusion protein, vectors carrying the nucleic acid molecules and host cells transformed with either the nucleic acid molecules or the vectors. In addition, it relates to such a fusion protein for use as a medicament, in particular for the treatment or prevention of Gram-negative bacterial infections, as diagnostic means or as cosmetic substance. The application also relates to the treatment or prevention of Gram-negative bacterial contamination of foodstuff, of food processing equipment, of food processing plants, of surfaces coming into contact with foodstuff, of medical devices, of surfaces in hospitals and surgeries.
