This part is a complete regulatory device sensitive to tetracycline. The first promoter is constitutively on and can express tetR, a protein that can repress the downstream promoter pTet in the absence of tetracycline(Tc). As a result, no fluorescence can be detected. In the presence of Tc, however, tetR can be repressed by Tc and repression over pTet can be removed, resulting in the expression of GFP and T7RNAP. Under such circumstances, positive feedback can be achieved and obvious fluorescence can be observed. Sequence and Features
