Enzyme Class:
Biological Properties
General Function:Signal transduction mechanisms
Specific Function:Member of the two-component regulatory system dcuR/dcuS. Involved in the C4-dicarboxylate-stimulated regulation of the genes encoding the anaerobic fumarate respiratory system (frdABCD; nuoAN; dcuB; dcuC; sdhCDAB; etc.). Weakly regulates the aerobic C4-dicarboxylate transporter dctA. Activates dcuR by phosphorylation
