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

The DNA recognition sequence for the transcriptional activator, CII protein, which is critical for lysogenization by bacteriophage lambda, overlaps the -35 region of the P(RE) promoter. Data presented here show that activation by CII does not change

Two Escherichia coli isolates were recovered from the blood of two cancer patients and were demonstrated to produce high levels of the AmpC β-lactamase with isoelectric points of >9.0. The hypertranscription of ampC RNA was observed by Northern blot

sigma S is an alternate sigma factor which functions with RNA polymerase to activate transcription of genes that are involved in a number of stress responses, including stationary-phase survival and osmoprotection. The similarity of the sigma S prote

Mutated variants of the predicted promoter of the countertranscript of the Chlamydia trachomatis plasmid were tested by in vitro transcription with chlamydial extract. A 3-bp deletion within the -10 region of the putative promoter caused the RNA poly

Methylation-interference assays have been used to identify guanine residues that make important contacts with RNA polymerase during open-complex formation at two related Escherichia coli promoters. Methylation of lower-strand G-31 at a gal consensus

The Bacillus subtilis global regulator AbrB is a DNA-binding protein composed of six identical monomers of 96 amino acids that shows specificity to the promoter regions of its target genes including its own. We have sequenced thirteen previously unch

Transcription from the TOL plasmid meta-cleavage pathway operon promoter Pm is dependent on the XylS regulator activated by benzoate effectors or after XylS overproduction. We have generated 5' deletions in Pm and have analyzed expression from wild-t

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

Mycobacterial SigE and SigH both initiate transcription from the sigB promoter, suggesting that they recognize similar sequences. Through mutational and primer extension analyses, we determined that SigE and SigH recognize nearly identical promoters,
