Characterization of Escherichia coli glnL mutations affecting nitrogen regulation.

Journal of bacteriology - 1 Jul 1992

Atkinson M R, Ninfa A J

Abstract excerpt

Nitrogen regulator II (NRII), the product of the Escherichia coli glnL (ntrB) gene, regulates the activation of transcription of glnA and the Ntr regulon by catalyzing the phosphorylation and dephosphorylation of the transcription factor NRI. Previous results have indicated that under conditions of nitrogen excess, transcriptional activation is prevented by an NRI-phosphate phosphatase activity that is observed...
