AbstractNatural killer lysin (NK-lysin), produced by cytotoxic T lymphocytes and natural killer cells, is a cationic antimicrobial peptide that has a broad antimicrobial spectrum, including bacteria, viruses, and parasites. Nevertheless, the implication of NK-lysin in the protection against bacterial infection is not aware in common carp. In this study, six different NK-Iysin genes (nkl1, nkl2, nkI3, nkl4, nkl5 and nkl6) were identified in the common carp genome. Each of the mature peptides of common carp NK-lysin has six well-conserved cysteine residues, and shares a Saposin B domain, characteristic of saposin-like protein (SAID) family. The gene nkl1 contains 5 extrons and 4 introns, and nkl2, nkl3, nkl4 or nk15 contains 4 extrons and 3 introns, however, the nkl6 has 3 extrons and 2 introns. By quantitative real-time PCR, nkl2 transcripts were predominantly expressed in spleen of healthy common carp, while elevated mainly in gill and spleen upon Aeromonas hydrophila infection. The recombinant NK-lysin-2 purified from Pichia pastoris shows antibacterial activity against Staphylococcus aureus (Gram-positive), and Escherkhia coil M15, Aeromonas hydrophila, as well as Edwardsiella tarda (Gram-negative), the latter two are important pathogens of aquaculture. Our results indicate that NK-lysin in common carp might play an important role in fish immune response by enhancing antibacterial defense against bacterial pathogens.
