CC -!- FUNCTION: Catalytic subunit of the periplasmic nitrate reductase
CC complex NapAB. Receives electrons from NapB and catalyzes the reduction
CC of nitrate to nitrite. {ECO:0000255|HAMAP-Rule:MF_01630}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 Fe(II)-[cytochrome] + 2 H(+) + nitrate = 2 Fe(III)-
CC [cytochrome] + H2O + nitrite; Xref=Rhea:RHEA:12909, Rhea:RHEA-
CC COMP:11777, Rhea:RHEA-COMP:11778, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16301, ChEBI:CHEBI:17632,
CC ChEBI:CHEBI:29033, ChEBI:CHEBI:29034; EC=1.9.6.1;
CC Evidence={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; Evidence={ECO:0000255|HAMAP-Rule:MF_01630};
CC Note=Binds 1 molybdenum-bis(molybdopterin guanine dinucleotide) (Mo-
CC bis-MGD) cofactor per subunit. {ECO:0000255|HAMAP-Rule:MF_01630};
CC -!- SUBUNIT: Component of the periplasmic nitrate reductase NapAB complex
CC composed of NapA and NapB. {ECO:0000255|HAMAP-Rule:MF_01630}.
CC -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000255|HAMAP-Rule:MF_01630}.
CC -!- SIMILARITY: Belongs to the prokaryotic molybdopterin-containing
CC oxidoreductase family. NasA/NapA/NarB subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01630}.
