In vitro analysis of a constitutively active mutant form of the Escherichia coli global transcription factor FNR

The Escherichia coli transcription factor FNR regulates expression of genes required for the metabolic switch between aerobic and anaerobic respiration. In order to investigate how FNR controls transcription of its target operons, DNA binding was examined for both the wild-type (WT) FNR protein and...
