Protein

Periplasmic nitrate reductase

Gene

napA

Organism
Shigella sonnei
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

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

Caution
