Colicin E2 DNase domain "miniColicin"

Colicin E2 is a peptide, that is toxic to coliform bacteria. It is one of a group of proteins of this type, it being a nicking endonuclease. It has a corresponding activity inhibiting protein called immunity protein Im2, which is also in the registry under the name BBa_K1976027.

Usage

The Colicin E2 immunity protein (BBa_K1976027 and BBa_K1976028) can be used in combination with the Colicin E2 DNase. Due to to the high binding affinity of the immunity protein to the DNase domain, it can be used to fuse proteins.
