UniprotKB/SwissProt ID: NAPA_ECOLI (P33937)
Gene Name: napA
Synonyms: yojC, yojD, yojE
Organism: Escherichia coli (strain K12).
Function: 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 (By similarity).
