CC   -!- FUNCTION: Member of the two-component regulatory system NreB/NreC
CC       involved in the control of dissimilatory nitrate/nitrite reduction in
CC       response to oxygen. Phosphorylated NreC binds to a GC-rich palindromic
CC       sequence at the promoters of the nitrate (narGHJI) and nitrite (nir)
CC       reductase operons, as well as the putative nitrate transporter gene
CC       narT, and activates their expression (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- PTM: Phosphorylated by NreB. {ECO:0000250}.
