  • bacterium
  • The role of extracytoplasmic function (ECF) sigma factors in multiple metal homeostasis of the metallophilic bacterium Cupriavidus metallidurans was studied. (rsc.org)
  • RNA sequencing was used to predict 3084 operons in the genome of this bacterium, including 11 for ECF sigma factors, and to measure transcript abundances. (rsc.org)
  • Together, these data demonstrate on a global and systemic level how a robust network of ECF sigma factors and other regulators allow C. metallidurans to handle a mixture of toxic transition metal cations, which are conditions the bacterium faces in its natural environment. (rsc.org)
  • promoter
  • The promoter interaction of Mtb-SigH can be highly beneficial for understanding the regulation of gene expression of a pathogen and also extends a solid platform to predict promoters for other bacterial σ factors. (rsc.org)
  • A reporter gene expression assay examining the expression of chloramphenicol acetyltransferase from the promoter regions from complex cyanobacterial gene clusters was used to show that sigma factor All7608 is capable of recognizing multiple cyanobacterial promoters in E. coli. (oregonstate.edu)
  • resistance
  • The three ECF sigma factors RpoI, RpoJ and RpoK synchronized iron homeostasis with that of other divalent metal cations, RpoO, RpoL and RpoM magnesium and phosphorous homeostasis with that of zinc and with cadmium resistance. (rsc.org)
  • RpoE
  • Factors RpoE, CnrH and RpoP controlled the response to nickel and cobalt, RpoQ and RpoR may be assigned to the thiol and sulfide metabolism. (rsc.org)
  • sporulation
  • In light of previous work showing that spoIIIG is subject to positive autoregulation, we propose that Lon protease is responsible (possibly by causing degradation of sigma G) for preventing sigma G-directed transcription of spoIIIG and hence the accumulation of sigma G in cells that are not undergoing sporulation.
