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 (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- PTM: Phosphorylated and activated by DcuS. {ECO:0000250}.
