the nap operon of Escherichia coli K-12, encoding a periplasmic nitrate reductase, encodes seven proteins. The catalytic complex in the periplasm, NapANapB receives electrons from the quinol pool via the membrane-bound cytochrome NapC. Like NapA, B and C, NapD, is also essential for Nap activity. None of the remaining three polypeptides, NapF, G and H, which are predicted to encode non-heme, iron-sulfur proteins, are essential for Nap activity |
