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.
CC {ECO:0000256|ARBA:ARBA00024827}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC histidine.; EC=2.7.13.3; Evidence={ECO:0000256|ARBA:ARBA00000085};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|ARBA:ARBA00001966};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496}.
