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. NreB functions as a direct oxygen sensor histidine
CC       kinase which is autophosphorylated, in the absence of oxygen, probably
CC       at the conserved histidine residue, and transfers its phosphate group
CC       probably to a conserved aspartate residue of NreC. NreB/NreC activates
CC       the expression of the nitrate (narGHJI) and nitrite (nir) reductase
CC       operons, as well as the putative nitrate transporter gene narT (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC         histidine.; EC=2.7.13.3;
CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000305};
CC       Note=Binds 1 [4Fe-4S] cluster. {ECO:0000305};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- PTM: Autophosphorylated. {ECO:0000250}.
