CC   -!- FUNCTION: Part of the ABC transporter complex NrtABCD involved in
CC       nitrate uptake (PubMed:7767600, PubMed:8437564). The complex is
CC       probably also involved in nitrite transport (PubMed:7767600). Probably
CC       responsible for the translocation of the substrate across the membrane
CC       (PubMed:7767600). {ECO:0000269|PubMed:8437564,
CC       ECO:0000305|PubMed:7767600}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (NrtC and
CC       NrtD), two transmembrane proteins (NrtB) and a solute-binding protein
CC       (NrtA). {ECO:0000305|PubMed:7767600}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305|PubMed:7767600};
CC       Multi-pass membrane protein {ECO:0000255}.
CC   -!- DISRUPTION PHENOTYPE: Mutant is unable to grow on nitrate, but grows
CC       normally with nitrite or ammonium as the nitrogen source.
CC       {ECO:0000269|PubMed:8437564}.
CC   -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC       permease family. CysTW subfamily. {ECO:0000305}.
