Functioni

Colicins are polypeptide toxins produced by and active against E.coli and closely related bacteria.
This is a calcium-requiring inhibitor for murein biosynthesis; it causes lysis of sensitive cells accompanied by murein degradation. The target site is possibly the cytoplasmic membrane.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
