[[http://www.uniprot.org/uniprot/CEA5_ECOLX CEA5_ECOLX]] Colicins are polypeptide toxins produced by and active against E.coli and closely related bacteria. This colicin is an endonuclease. [[http://www.uniprot.org/uniprot/IMM5_ECOLX IMM5_ECOLX]] This protein is able to protect a cell, which harbors the plasmid ColE5 encoding colicin E5, against colicin E5.
