CC   -!- FUNCTION: Member of the two-component regulatory system DcuR/DcuS.
CC       Involved in the C4-dicarboxylate-stimulated regulation of the genes
CC       encoding the anaerobic fumarate respiratory system (frdABCD; nuoAN;
CC       dcuB; dcuC; sdhCDAB; etc.). Weakly regulates the aerobic C4-
CC       dicarboxylate transporter dctA. Activates DcuR by phosphorylation (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   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC       membrane protein {ECO:0000250}.
CC   -!- DOMAIN: The periplasmic domain is involved in C4-dicarboxylate binding
CC       and sensing. The structural disorder in the cytoplasmic PAS domain has
CC       an important role in signal transduction to the kinase domain and may
CC       be the decisive structural feature that characterizes the activated
CC       kinase (By similarity). {ECO:0000250}.
CC   -!- PTM: Autophosphorylated. The phosphoryl group is rapidly transferred to
CC       DcuR (By similarity). {ECO:0000250}.
