[[https://www.uniprot.org/uniprot/IMM9_ECOLX IMM9_ECOLX]] This protein is able to protect a cell, which harbors the plasmid ColE9 encoding colicin E9, against colicin E9, it binds specifically to the DNase-type colicin and inhibits its bactericidal activity. [[https://www.uniprot.org/uniprot/CEA9_ECOLX CEA9_ECOLX]] This plasmid-coded bactericidal protein is an endonuclease active on both single- and double-stranded DNA but with undefined specificity. Colicins are polypeptide toxins produced by and active against E.coli and closely related bacteria.
