In vitro, the sigma(s) subunit of RNA polymerase (RNAP), RpoS, recognizes nearly identical -35 and -10 promoter consensus sequences as the vegetative sigma70. In vivo, promoter selectivity of RNAP holoenzyme containing either sigma(s) (Esigma(s)) or

Ketolides represent a new generation of macrolide antibiotics. In order to identify the ketolide-binding site on the ribosome, a library of Escherichia coli clones, transformed with a plasmid carrying randomly mutagenized rRNA operon, was screened fo

In order to meet osmotic challenges in the gastrointestinal tract, enteric bacteria rapidly accumulate salts of glutamate and other weak organic acids. The ensuing transcriptional activation is mediated by unknown elements at sigma38 (rpoS)-dependent

One of the under-represented genes identified by cDNA representational difference analysis (RDA) between avirulent Entamoeba histolytica strain Rahman and virulent strain HM-1:IMSS was the amoebic light (35 kDa) subunit of the Gal/GalNac lectin compl

Degradation of protocatechuate in Pseudomonas putida is accomplished by the products of the pca genes (pcaH,G, pcaBDC, pcaI, J and pcaF ). In P. putida, all these genes (with the exception of pcaH,G ) are activated by the regulatory protein PcaR, in

The FixL/FixJ two-component system is a global regulator of nitrogen-fixation genes in Rhizobium meliloti. The transcriptional activator FixJ contains two modules: its N-terminal module is homologous with other two-component regulators; its C-termina

NsrR is a nitric oxide (NO)-sensitive transcription repressor that controls NO metabolism in a wide range of bacteria. In Bacillus subtilis, NsrR represses transcription of the nitrite reductase (nasDEF) genes that are under positive control of the R

Summary A prominent feature of the promoters of Bordetella pertussis fimbrial subunit genes fim2, fim3 and fimX is the presence of a ‘C-stretch’, a monotonic run of C residues. The C-stretch renders these genes capable of phase variation, through

The bacterial RNA polymeras holoenzyme consists of a catalytic core enzyme in complex with a sigma factor that is required for promoter-specific transcription initiation. During initiation, members of the sigma(70) family of sigma factors contact two

6S RNA binds sigma70-RNA polymerase and downregulates transcription at many sigma70-dependent promoters, but others escape regulation even during stationary phase when the majority of the transcription machinery is bound by the RNA. We report that co
