[1]	NUCLEOTIDE SEQUENCE [GENOMIC DNA]. STRAIN=A15; Rediers H., Vanderleyden J., De Mot R.; "Nitrate reduction in Pseudomonas stutzeri A15 and its contribution to rice and wheat rhizosphere fitness."; Submitted (SEP-2005) to the EMBL/GenBank/DDBJ databases.

Comments

FUNCTION: Catalytic subunit of the periplasmic nitrate reductase (NAP). Only expressed at high levels during aerobic growth. NapAB complex receives electrons from the membrane-anchored tetraheme protein napC, thus allowing electron flow between membrane and periplasm. Essential function for nitrate assimilation and may have a role in anaerobic metabolism (By similarity).
CATALYTIC ACTIVITY: Nitrite + acceptor = nitrate + reduced acceptor.
COFACTOR: Binds 1 4Fe-4S cluster (By similarity).
COFACTOR: Binds 1 molybdenum ion per subunit (By similarity).
COFACTOR: Binds 2 molybdopterin guanine dinucleotide (MGD) groups per subunit (By similarity).
SUBUNIT: Interacts with napB (By similarity).
SUBCELLULAR LOCATION: Periplasm (By similarity).
PTM: Predicted to be exported by the Tat system. The position of the signal peptide cleavage has not been experimentally proven.
SIMILARITY: Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/napA/narB subfamily.
