TranscriptomicsDetermine whether Streptomyces venezuelae protein SepH (vnz_27360) binds DNA and where
SepH was identified having a potential role in sporulation following ChIP-seq analysis that showed the sepH gene is under the control of the WhiA and WhiB transcription factors (Bush et al., 2013; Bush et al., 2016). Since SepH has a helix-turn-helix motif, this ChIP-Seq experiment was carried out t...

GenomicsChIP-Seq of the Streptomyces venezuelae regulator BldD and its D116A mutant.
The dimerization and binding of DNA by BldD is affected by its interaction with cyclic di-GMP. The D116A mutant of BldD is partially impaired in its biding of cyclic di-GMP. ChIP-Seq was carried out to determine the difference in the degree of DNA binding by the wild type and D116A mutated BldD in S...

TranscriptomicsWhiA and WhiB of Streptomyces venezuelae depend on each other for binding DNA
WhiB regulon, as determined by ChIP-Seq turned out to be identical to the WhiA regulon leading to the speculation that the two proteins might be required to work together to bind DNA. In this experiment WhiA ChIP-Seq was done in a whiB deletion background and, WhiB ChIP-Seq was done in a whiA deleti...

TranscriptomicsChIP-Seq to determine binding sites of transcription factor BldO in the genome of Streptomyces venezuelae
The transcription factor BldO was identified as a target of WhiAB in an earlier ChIP-Seq experiment. This experiment was conducted to determine the targets of BldO in the Streptomyces venezuelae genome.

TranscriptomicsChIP-Seq to determine the binding sites of the transcription factor WhiB in the genome of Streptomyces venezuelae
WhiB is the founding member of a family of proteins (the WhiB-like [Wbl] family) that carry a [4Fe-4S] iron-sulfur cluster. It is essential for the process of developmentally controlled cell division leading to sporulation in Streptomyces species. This ChIP-Sea was carried out to determine unambiguo...

TranscriptomicsMutation of the cysteine residues that coordinate the WhiB [4Fe-4S] cluster prevents in vivo DNA binding by both WhiB and WhiA
The purpose of this experiment was to show that the iron-sulphur cluster ([4Fe-4S]) of whiB is essential for the DNA binding by WhiB and WhiA. The \\"serine version of whiB\\" mentioned below is a whiB in which the 4 cysteine residues which coordinate the [4Fe-4S] cluster were mutated to serines. Ch...

TranscriptomicsTranscriptional profiling of the developmental gene whiB deletion mutant of Streptomyces venezuelae ATCC 10712 at 7 time points from 8 to 20 hours of growth
WhiB is the founding member of a family of proteins (the WhiB-like [Wbl] family) that carry a [4Fe-4S] iron-sulfur cluster and play key roles in diverse aspects of the biology of actinomycetes, including pathogenesis, antibiotic resistance, and the control of development. In Streptomyces, WhiB is es...

TranscriptomicsTranscriptional profiling of the developmental gene whiA deletion mutant of Streptomyces venezuelae ATCC 10712 at 7 time points from 8 to 20 hours of growth.
WhiA is an unusual transcriptional regulator found in Streptomyces species related to eukaryotic homing endonucleases. It plays a central role in sporulation in these bacteria. The aim of this transcription profiling experiment was to measure genome wide transcript levels in the wild type and the wh...

GenomicsIdentification by ChIP-Seq of the binding sites of the extracytoplasmic function (ECF) sigma factor SigE in the genome of Streptomyces coelicolor A3(2) M600.
SigE is a sigma factor found in Streptomyces species and is the key regulator of cell envelope stress response in Streptomyces coelicolor. This ChIP-Seq experiment was carried out to determine the binding sites of SigE under conditions of cell envelope stress induced by 10 ug / ml vancomycin for 30...

TranscriptomicsTranscriptional profiling of the sigma factor sigE deletion mutant of Streptomyces coelicolor (J2130) at 0, 30, 60 and 90 minutes after treatment with sub-lethal concentration of vancomycin.
SigE is a sigma factor found in Streptomyces species and is the key regulator of cell envelope stress response in Streptomyces coelicolor. To determine the regulon of SigE under conditions of cell envelope stress, 10 ug / ml vancomycin was used to induce cell envelope stress in the wild type and a s...
