The crystal structure of the DNase domain of colicin E7 in complex with its inhibitor Im7 protein.
BACKGROUND Colicin E7 (ColE7) is one of the bacterial toxins classified as a DNase-type E-group colicin. The cytotoxic activity of a colicin in a colicin-producing cell can be counteracted by bindingExpand
