Abstract excerpt
The Escherichia coli NarL protein is a global gene regulatory factor that activates transcription at many target promoters in response to nitrate and nitrite ions. Although most NarL-dependent promoters are also co-dependent on a second transcription factor, FNR protein, two targets, the yeaR and ogt promoters, are activated by NarL alone with no involvement of FNR. Biochemical and genetic studies presented here...
