International audience; Synthesis of the major toxin proteins of the diarrheal pathogen, Clostridium difficile, is dependent on the activity of TcdR, an initiation (sigma) factor of RNA polymerase. The synthesis of TcdR and the activation of toxin ge

International audience; In many Gram-negative bacteria, including Salmonella enterica serovar Typhimurium (S. Typhimurium), the sigma factor RpoS/σ S accumulates during stationary phase of growth, and associates with the core RNA polymerase enzyme (

The general stress response in Enterobacteria, like Escherichia coli or Salmonella, is controlled by the transcription factor σS, encoded by the rpoS gene, which accumulates during stationary phase growth and associates with the core RNA polymerase

TxeR, a sigma factor that directs Clostridium difficile RNA polymerase to recognize the promoters of two major toxin genes, was shown to stimulate its own synthesis. Whether expressed in C. difficile , Clostridium perfringens , or Escherichia coli ,

Although polymicrobial infections, caused by combinations of viruses, bacteria, fungi and parasites, are being recognised with increasing frequency, little is known about the occurrence of within-species diversity in bacterial infections and the mole

Proteins that bind σ factors typically attenuate the function of the σ factor by restricting its access to the RNA polymerase (RNAP) core enzyme. An exception to this general rule is the Crl protein that binds the stationary-phase sigma factor σ S
