SaurJH9_2415 Nitrogen regulation protein C Member of the two-component regulatory system nreB/nreC involved in the control of dissimilatory nitrate/nitrite reduction in response to oxygen. Phosphorylated nreC binds to a GC-rich palindromic sequence at the promoters of the nitrate (narGHJI) and nitrite (nir) reductase operons, as well as the putative nitrate transporter gene narT, and activates their expression (By similarity).
