Colicin E2 is a type of Colicin, a bacteriocin made by E. coli which acts against other nearby E. coli to kill them with its DNase activity; it digests the host genome, leading to its death.
Synthesis and release
The ColE2 operon is encoded on a plasmid in E. coli, alongside its Colicin Immunity Protein, Imm. This protects the colicinogenic cell from the cytotoxic activity of the colicin.

Colicin E2 binds to the BtuB receptor on the target E. coli cell to begin its translocation across the membrane. This structure shows the binding between (blue) and the (green).
