CC   -!- FUNCTION: Catalytic subunit of the periplasmic nitrate reductase
CC       (NAP). Only expressed at high levels during aerobic growth. NapAB
CC       complex receives electrons from the membrane-anchored tetraheme
CC       protein NapC, thus allowing electron flow between membrane and
CC       periplasm. Essential function for nitrate assimilation and may
CC       have a role in anaerobic metabolism. {ECO:0000255|HAMAP-
CC       Rule:MF_01630}.
CC   -!- CATALYTIC ACTIVITY: Nitrite + acceptor = nitrate + reduced
CC       acceptor. {ECO:0000255|HAMAP-Rule:MF_01630}.
CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01630};
CC       Note=Binds 1 [4Fe-4S] cluster. {ECO:0000255|HAMAP-Rule:MF_01630};
CC   -!- COFACTOR:
CC       Name=Mo-bis(molybdopterin guanine dinucleotide);
CC         Xref=ChEBI:CHEBI:60539;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01630};
CC       Note=Binds 1 molybdenum-bis(molybdopterin guanine dinucleotide)
CC       (Mo-bis-MGD) cofactor per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01630};
CC   -!- SUBUNIT: Interacts with NapB. {ECO:0000255|HAMAP-Rule:MF_01630}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000255|HAMAP-Rule:MF_01630}.
CC   -!- PTM: Predicted to be exported by the Tat system. The position of
CC       the signal peptide cleavage has not been experimentally proven.
CC   -!- SIMILARITY: Belongs to the prokaryotic molybdopterin-containing
CC       oxidoreductase family. NasA/NapA/NarB subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01630}.
CC   -!- SIMILARITY: Contains 1 4Fe-4S Mo/W bis-MGD-type domain.
CC       {ECO:0000255|HAMAP-Rule:MF_01630}.
