CC   -!- FUNCTION: Probably part of a high-affinity binding-protein-
CC       dependent transport system for nitrate; probably responsible for
CC       the translocation of the substrate across the membrane.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000255|PROSITE-ProRule:PRU00441}.
CC   -!- SIMILARITY: Belongs to the binding-protein-dependent transport
CC       system permease family. CysTW subfamily. {ECO:0000305}.
