CC -!- FUNCTION: Catalyzes nitrite uptake and nitrite export across the
CC cytoplasmic membrane. Is up to 10-fold more active than NarK or NarU in
CC nitrite uptake for subsequent reduction in the cytoplasm by the
CC NirB/NirD nitrite reductase. {ECO:0000269|PubMed:11967075,

CC {ECO:0000269|PubMed:15919996}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:15919996}.
CC -!- SIMILARITY: Belongs to the FNT transporter (TC 2.A.44) family.
CC {ECO:0000305}.
