Response regulator DegU of Listeria monocytogenes controls temperature-responsive flagellar gene expression in its unphosphorylated state.
We demonstrate that in Listeria monocytogenes, temperature-responsive transcriptional control of flagellar genes does not rely on the phosphorylation of the conserved phosphorylation site (D55) in the receiver domain of response regulator DegU. Furthermore, proper control of DegU-regulated genes involved in ethanol tolerance and virulence is independent of receiver phosphorylation.
