Arginine regulon repression and derepression

Analysis of cells with the arginine (Arg) regulon fully or partially repressed, or derepressed. Genes of the Arg regulon are coordinately repressed by the Arg repressor (ArgR) in response to Arg. Results provide insight into ArgR-mediated repression of arginine biosynthesis and uptake genes.

Transcriptome analysis of the arginine regulon in E.coli

(Submitter supplied) Analysis of the response to arginine of the Escherichia coli K-12 transcriptome by microarray hybridization and real-time quantitative PCR provides a first coherent quantitative picture of the ArgR-mediated repression of arginine biosynthesis and uptake genes. Transcriptional repression was shown to be the major control mechanism of the biosynthetic genes, leaving only limited room for additional transcriptional or post-transcriptional regulations. more...

ChIP-chip of E. coli K-12 MG1655 with antibody against PurR-8myc under various conditions.

(Submitter supplied) We integrated transcription factor binding regions and mRNA transcript abundance to elucidate the PurR regulon experimentally. To measure transcription factor binding at a genome scale, we employed a ChIP-chip method to derivative strains of E. coli K-12 MG1655 harboring PurR-8myc under various conditions.

In vivo probing of the DNA-binding Architecture by bacterial arginine repressor

(Submitter supplied) Although DNA motifs recognized by the transcription factors (TFs) have been determined, challenges remain in probing in vivo architecture of TF-DNA complexes on a genome-wide scale. Here, we show in vivo architecture of Escherichia coli arginine repressor (ArgR)-DNA complexes using chromatin immunoprecipitation coupled with sequencing (ChIP-exo). The identified 62 ArgR-binding loci were classified into three groups, comprised of single, double, and triple peak-pairs, respectively. more...

Response and adaptation to growth with low glucose concentration

(Submitter supplied) The faecal indicator bacterium Escherichia coli K12 was used to study the cellular events that take place at the transcription level using the microarray technology during short-term (physiological) and long-term (genetic) adaptation to slow growth under limited nutrient supply. Short-term and long-term adaptation were assessed by comparing the mRNA levels isolated after 40 or 500 hours of glucose-limited continuous culture at a dilution rate of 0.3 h-1 with those from batch culture with glucose excess. more...
