    Functioni

    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.UniRule annotation

    Catalytic activityi

    Nitrite + acceptor = nitrate + reduced acceptor.UniRule annotation

    Cofactori

    Binds 1 4Fe-4S cluster.UniRule annotation
    Binds 1 molybdenum-bis(molybdopterin guanine dinucleotide) (Mo-bis-MGD) cofactor per subunit.UniRule annotation
