A vector contains the nitR gene under the control of the nitA promoter in a separate operon, the expression of vector is used, upon the addition of the inducer. The inducer–NitR protein complex activates the transcription of both the target gene(s) and nitR and increased level of NitR results in a very high level of production of the target protein(s). Which type of inducer using by nitR?
