Kil protein, bacteriophage P22-type (IPR020298)

Short name: Kil_phage_P22-type

Family relationships



The bacteriophage P22 kil gene, like lambda kil, kills the host cell when it is expressed. The two kil genes, although analogous in cell killing and map location, have no sequence homology. The functions of the P22 and lambda kil genes are not known; however, P22 kil is essential for lytic growth in the absence of abc. Gene arf (accessory recombination function, IPR020293) is located just upstream from erf and is essential for P22 growth in the absence of kil [PMID: 2738922].
