Comparison of the nucleotide-resolution, genome-wide, 5'-end maps of the transcriptomes of Escherichia coli K12 strain BW25113 and Streptomyces coelicolor A3(2) strain M145

ABSTRACT: The differential RNA-seq data contained within this entry is complemented by global RNA-seq. S. coelicolor and E. coli reference strains were grown in batch culture with shaking. The E. coli sample was extracted during mid-exponential growth, while the S. coelicolor sample was extracted at the start of pigmented antibiotic production. Each of the two samples was incubated with or without TAP (tobacco acid pyrophosphatase) before library construction. Thus, 4 libraries were analysed. TAP treatment allows the cloning and sequencing of 5' ends that were originally triphosphorylated.

Nucleotide-resolution, genome-wide, 5'-end maps of the transcriptome of Propionibacterium acnes (cultured with and without potassium downshift)

Project description:The differential RNA-seq data contained within this entry is complemented by global RNA-seq and microarray data, which is also deposited in GEO. Duplicate cultures of Propionibacterium acnes strain KPA171202 were grown exponentially in batch culture under anaerobic growth. Samples were taken following subculture with and without potassium downshift (i.e. removal from medium). This produced 4 samples; 2 replicates x 2 conditions. Aliquots of each of the 4 samples were then incubated with or without incubation TAP (tobacco acid pyrophosphatase) before library construction. Thus, 8 libraries were analysed. TAP treatment allows the cloning and sequencing of 5' ends that were originally triphosphorylated.

Project description:This data contained within this entry was produced as part of a study that included differential RNA-sequencing and microarray analysis. The results of the latter two have also been deposited in GEO Duplicate cultures of Propionibacterium acnes strain KPA171202 were grown exponentially in Holland Synthetic Medium (Holland et al.1979. J Appl Bacteriol 47: 383), which supports reproducible anaerobic growth. Samples were taken following subculture with and without potassium downshift (i.e. removal from medium).

sRNA scr5239 involved in important feedback loop of S. coelicolor central metabolism

Project description:The project is focused on the highly conserved sRNA scr5329 in Streptomyces coelicolor. A proteomics approach revealed that the sRNA regulates several metabolic enzymes, among them the Phosphoenolpyruvate-Carboxykinase (PEPCK), a key enzyme of the central carbon metabolism. The sRNA scr5239 promotes its degradation on the post-transcriptional level. The expression itself is dependent on the global transcriptional regulator DasR, which is N-acetylglucosamine-responsive thereby creating a feedback regulation. By post-transcriptional regulation of PEPCK and likely more targets, scr5239 adds an additional layer to the DasR regulatory network, providing a tool to control the metabolism in dependency to the carbon source.

Genes required for aerial growth, cell division, and chromosome segregation are targets of WhiA before sporulation in Streptomyces venezuelae.

Project description:WhiA is a highly unusual transcriptional regulator related to a family of eukaryotic homing endonucleases. WhiA is required for sporulation in the filamentous bacterium Streptomyces, but WhiA homologues of unknown function are also found throughout the Gram-positive bacteria. To better understand the role of WhiA in Streptomyces development and its function as a transcription factor, we identified the WhiA regulon through a combination of chromatin immunoprecipitation-sequencing (ChIP-seq) and microarray transcriptional profiling, exploiting a new model organism for the genus, Streptomyces venezuelae, which sporulates in liquid culture. The regulon encompasses ~240 transcription units, and WhiA appears to function almost equally as an activator and as a repressor. Bioinformatic analysis of the upstream regions of the complete regulon, combined with DNase I footprinting, identified a short but highly conserved asymmetric sequence, GACAC, associated with the majority of WhiA targets. Construction of a null mutant showed that whiA is required for the initiation of sporulation septation and chromosome segregation in S. venezuelae, and several genes encoding key proteins of the Streptomyces cell division machinery, such as ftsZ, ftsW, and ftsK, were found to be directly activated by WhiA during development. Several other genes encoding proteins with important roles in development were also identified as WhiA targets, including the sporulation-specific sigma factor (WhiG) and the diguanylate cyclase CdgB. Cell division is tightly coordinated with the orderly arrest of apical growth in the sporogenic cell, and filP, encoding a key component of the polarisome that directs apical growth, is a direct target for WhiA-mediated repression during sporulation.

Metabolic switching in Streptomyces coelicolor wild type, time series under glutamate depletion condition

Project description:During the lifetime of a fermenter culture, the soil bacterium S. coelicolor undergoes a major metabolic switch from exponential growth to antibiotic production. We have studied gene expression patterns during this switch, using a specifically designed Affymetrix GeneChip and a high-resolution time-series of fermenter-grown samples. This time series was conducted using medium leading to glutamate depletion and the cultivation conditions as published in Nieselt et al. BMC Genomics 2010, performed with the Streptomyces coelicolor wild type strain M145E. 30 samples, no replicates; one hour resolution from 20-32h and 40-42h; half our resolution from 32-40 h; two hour resolution 44-58h; sample missing for 29 and 34 h

Pervasive endonucleolytic cleavage mediated by the direct entry mode of RNase E

Project description:Here we show using RNA-seq that cleavage by RNase E direct entry pervades in both the degradation and processing of RNA. We also give further evidence that direct entry is facilitated by cooperative interaction with segments in addition to the ones in which cleavage occurs. RNA seq profiles were compared between a temperature-sensitive mutant of rne and its congenic wild-type incubated at a non-permissive temperature. RNA seq profiles were also compared between samples before and after incubation with a 5'-sensing mutant of RNase E in vitro.
