== Function ==
[https://www.uniprot.org/uniprot/CEA1_ECOLX CEA1_ECOLX] This colicin is a channel-forming colicin. This class of transmembrane toxins depolarize the cytoplasmic membrane, leading to dissipation of cellular energy.  Colicins are polypeptide toxins produced by and active against E.coli and closely related bacteria.
