Protein

Periplasmic nitrate reductase

Gene

napA

Organism
Haemophilus influenzae (strain PittEE)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

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
