lacIq-T7-ccdB

This part contains a ccdB gene under control of a T7-promotor. CcdB is a bacterial toxin that interferes with topoisomerase unit GyrA. The toxin CcdB can be neutralized by its antitoxin CcdA. The T7-promoter allows for the controlled expression of CcdB.The inducible promoter is a combination of an operator LacO and a T7-promoter. The operator may be switched on or off. This, in turn, controls the transcription of the gene. The repressors (LacI and LacIq), inhibit the transcription by binding with a regulatory element, called the operator LacO. LacIq binds the operator LacO more tightly than LacI.
