Function

function

Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite.

Catalytic activity

Cofactor

Protein has several cofactor binding sites:
Mo-bis(molybdopterin guanine dinucleotide) (UniProtKB | Rhea| CHEBI:60539 )

Note: Binds 1 molybdenum-bis(molybdopterin guanine dinucleotide) (Mo-bis-MGD) cofactor per subunit.
[4Fe-4S] cluster (UniProtKB | Rhea| CHEBI:49883 )

Note: Binds 1 [4Fe-4S] cluster.
