Many [[Colicin]]s exhibit enzymatic DNase activity as their cytotoxic activity to kill the targeted ''E. coli'' cell. The structure shows the DNase domain of [[Colicin E9]] bound to its [[Colicin Immunity Protein]], [[Im9]]. | Many [[Colicin]]s exhibit enzymatic DNase activity as their cytotoxic activity to kill the targeted ''E. coli'' cell. The structure shows the DNase domain of [[Colicin E9]] bound to its [[Colicin Immunity Protein]], [[Im9]]. These kill the cell by selectively cleaving the DNA throughout the genome, which ultimately leads to cell death as the damage is too great for the cell to repair itself. Rather than continue to live with a faulty genome, the cell kills itself. | ||
