Role of the promoter in activation of transcription by nitrogen regulator I phosphate in Escherichia coli.

Journal of bacteriology - 1 Feb 1990

Abstract excerpt

The protein nitrogen regulator I (NRI)-phosphate is known to activate the initiation of transcription of the Escherichia coli glnA gene. This activation is facilitated by the binding of the protein to NRI-specific sites located upstream of the sigma 54-dependent glnA promoter. To determine whether binding of NRI-phosphate to upstream sites is sufficient for activation, we placed several promoters not normally...
