Protein

Nitrate reductase

Gene

napA

Organism
Vibrio cholerae (strain MO10)
Status
Unreviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalytic subunit of the nitrate reductase (NAP). Only expressed at high levels during aerobic growth. NapAB complex receives electrons from the membrane-anchored tetraheme protein NapC. Essential function for nitrate assimilation and may have a role in anaerobic metabolism.UniRule annotation

Catalytic activityi

2 ferrocytochrome + nitrate + 2 H+ = 2 ferricytochrome + nitrite.UniRule annotationSAAS annotation
