Specific function: Acts as a sensor for nitrate/nitrite and transduces signal of nitrate/nitrite availability to the narL/narP proteins. NarQ probably activates narL and narP by phosphorylation. NarQ probably negatively regulates the narL protein by dephosphorylation [H]

COG id: COG3850

COG function: function code T; Signal transduction histidine kinase, nitrate/nitrite-specific

Gene ontology:

Cell location: Cell inner membrane; Multi-pass membrane protein [H]

Metaboloic importance: Non_Essential [C]

Operon status: Not Known

Operon components: None

Similarity: Contains 1 histidine kinase domain [H]
