RT   associated nitrogen-fixing bacterium Pseudomonas stutzeri A1501.";
RL   Submitted (APR-2006) to the EMBL/GenBank/DDBJ databases.
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 (By similarity).
CC   -!- CATALYTIC ACTIVITY: Nitrite + acceptor = nitrate + reduced
CC       acceptor.
CC   -!- COFACTOR: Binds 1 4Fe-4S cluster (By similarity).
CC   -!- COFACTOR: Binds 1 molybdenum ion per subunit (By similarity).
CC   -!- COFACTOR: Binds 2 molybdopterin guanine dinucleotide (MGD) groups
CC       per subunit (By similarity).
CC   -!- SUBUNIT: Interacts with napB (By similarity).
CC   -!- SUBCELLULAR LOCATION: Periplasm (By similarity).
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.
