DNase Activity
From Proteopedia
Many Colicins 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.
This shows just the DNase domain, as bound to Im9. Here instead shows just the immunity protein.
