RNA sequence requirements for NasR-mediated, nitrate-responsive transcription antitermination of the Klebsiella oxytoca M5al nasF operon leader.

Journal of molecular biology - 17 Sept 1999

Chai W, Stewart V

Abstract excerpt

In Klebsiella oxytoca, enzymes required for nitrate assimilation are encoded by the nasFEDCBA operon. Nitrate and nitrite induction of nasF operon expression is determined by a transcriptional antitermination mechanism, in which the nasR gene product responds to nitrate or nitrite and overcomes transcription termination at the factor-independent terminator site located in the nasF upstream leader region.
