General annotation (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. HAMAP-Rule MF_01630

Catalytic activity

Nitrite + acceptor = nitrate + reduced acceptor. HAMAP-Rule MF_01630

Cofactor

Binds 1 4Fe-4S cluster By similarity. HAMAP-Rule MF_01630

Binds 1 molybdenum-bis(molybdopterin guanine dinucleotide) (Mo-bis-MGD) cofactor per subunit By similarity.

Subunit structure

Interacts with NapB By similarity. HAMAP-Rule MF_01630

Subcellular location

Periplasm By similarity HAMAP-Rule MF_01630.

Post-translational modification

Predicted to be exported by the Tat system. The position of the signal peptide cleavage has not been experimentally proven. HAMAP-Rule MF_01630

Sequence similarities

Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.

Contains 1 4Fe-4S Mo/W bis-MGD-type domain.
