Phage lytic enzymes (enzybiotics) have gained attention as prospective tools to eradicate Gram-positive pathogens resistant to antibiotics. Attempts to purify the P16 endolysin of Staphylococcus aureus phage P68 were unsuccessful owing to the poor solubility of the protein. To overcome this limitation, we constructed a chimeric endolysin (P16-17) comprised of the inferred N-terminal d-alanyl-glycyl endopeptidase domain and the C-terminal cell wall targeting domain of the S. aureus phage P16 endolysin and the P17 minor coat protein, respectively. The domain swapping approach and the applied purification procedure resulted in soluble P16-17 protein, which exhibited antimicrobial activity towards S. aureus. In addition, P16-17 augmented the antimicrobial efficacy of the antibiotic gentamicin. This synergistic effect could be useful to reduce the effective dose of aminoglycoside antibiotics.
