CC   -!- FUNCTION: Member of the two-component regulatory system NtrB/NtrC,
CC       which controls expression of the nitrogen-regulated (ntr) genes in
CC       response to nitrogen limitation. Phosphorylated NtrC binds directly to
CC       DNA and stimulates the formation of open promoter-sigma54-RNA
CC       polymerase complexes. {ECO:0000250|UniProtKB:P0AFB8}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P0AFB8}.
CC   -!- PTM: Phosphorylated and dephosphorylated by NtrB.
CC       {ECO:0000250|UniProtKB:P0AFB8}.
