The respiratory nitrate reductase operons. (a) The major (expressed) operon also encodes the nitrate and nitrite transporters (narK-1, narK-2), two c-type cytochromes including ppcF, and two genes of molybdenum cofactor biosynthesis (moeA-2, moaA-2). (b) The minor operon (expression not detected) also encodes the Rieske iron-sulfur component of nitrite reductase (nirD) and a c-type cytochrome, but lacks a narJ gene.
