UniProtKB - Q48468 (NASR_KLEOX)
Protein
Nitrate regulatory protein
Gene
nasR
Organism
Klebsiella oxytoca
Status
Functioni
Nitrate- and nitrite-responsive positive regulator for nasFEDCBA operon expression. NasR protein binds to the factor-independent terminator site located in the nasF operon leader RNA to effect transcription antitermination.
