Colicin E3
From Proteopedia
Colicin E3 is a type of Colicin, a bacteriocin made by E. Coli which acts against other nearby E. Coli to kill them with its 16s rRNase activity; it digests the 16s ribosomal subunit, ultimately leading to the death of the cell.

Synthesis and release
Mechanism of uptake
ColE3 initially binds to the BtuB vitamin B12 receptor. Formation of this complex leads to the unfolding of the N terminal receptor binding coiled-coil domain of ColE3. [1]
