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. Under conditions of nitrogen
CC limitation, NtrB autophosphorylates and transfers the phosphoryl group
CC to NtrC. In the presence of nitrogen, acts as a phosphatase that
CC dephosphorylates and inactivates NtrC. {ECO:0000256|ARBA:ARBA00037696}.
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 -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
