CC -!- FUNCTION: Catalyzes nitrate uptake, nitrite uptake and nitrite export
CC across the cytoplasmic membrane (PubMed:2668029, PubMed:11967075,
CC PubMed:15667293, PubMed:16804183, PubMed:23665960, PubMed:25959928).
CC Functions as a nitrate/nitrite exchanger, and protons are unlikely to
CC be co-transported (PubMed:2668029, PubMed:15667293, PubMed:23665960,
CC PubMed:25959928). {ECO:0000269|PubMed:11967075,

CC ECO:0000269|PubMed:2668029}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=nitrate(in) + nitrite(out) = nitrate(out) + nitrite(in);
CC Xref=Rhea:RHEA:28743, ChEBI:CHEBI:16301, ChEBI:CHEBI:17632;
CC Evidence={ECO:0000269|PubMed:15667293, ECO:0000269|PubMed:23665960,
CC ECO:0000269|PubMed:25959928, ECO:0000305|PubMed:2668029};
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000269|PubMed:15919996,
CC ECO:0000269|PubMed:23665960, ECO:0000269|PubMed:25959928}; Multi-pass
CC membrane protein {ECO:0000269|PubMed:23665960,
CC ECO:0000269|PubMed:25959928}.
CC -!- INDUCTION: Highly expressed during anaerobic growth in the presence of
CC nitrate. {ECO:0000269|PubMed:16804183, ECO:0000269|PubMed:2668029}.
CC -!- DOMAIN: Each molecule contains 12 transmembrane helices, forming the N
CC bundle (TM1-6) and the C bundle (TM7-12) (PubMed:25959928). These N and
CC C bundles are connected with a linker loop between TM6 and TM7
CC (PubMed:25959928). The substrate-binding pocket is located at the
CC interface between the N and C bundles (PubMed:23665960,
CC PubMed:25959928). Substrate recognition is coupled to the transport
CC cycle by the concomitant movement of the transmembrane helices and the
CC key tyrosine and arginine residues in the substrate-binding site
CC (PubMed:25959928). {ECO:0000269|PubMed:23665960,
CC ECO:0000269|PubMed:25959928}.
CC -!- DISRUPTION PHENOTYPE: Deletion mutant, under conditions for the
CC induction of nitrate respiration, is unable to perform nitrate
CC transport (PubMed:2668029). The narK-narU double mutant is defective in
CC nitrate-dependent growth unless nitrate transport is facilitated by the
CC nitrate ionophore, reduced benzyl viologen (BV) (PubMed:11967075).
CC Deletion of both NarK and NirC also decreases nitrite uptake
CC (PubMed:11967075). {ECO:0000269|PubMed:11967075,
CC ECO:0000269|PubMed:2668029}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily.
CC Nitrate/nitrite porter (TC 2.A.1.8) family. {ECO:0000305}.
