Abstract
An isogenic mutant of Listeria monocytogenes EGD with a deletion of the response regulator gene degU showed a lack of motility due to the absence of flagella. In the present study, we used two-dimensional gel electrophoresis, mass-spectrometry and microarray analyses to identify the listerial genes that depend on DegU for expression. We found that the two L. monocytogenes operons encoding flagella-specific genes and the monocistronically transcribed flaA gene are positively regulated by DegU at 24 °C, but are not expressed at 37 °C.
