ChIP-Seq to determine the binding sites of the transcription factor WhiB in the genome of Streptomyces venezuelae

ABSTRACT: 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 unambiguously if WhiB functions as a transcription factor in Streptomyces venezuelae and also to determine its regulon.

INSTRUMENT(S): Illumina HiSeq 2000

<h4>Unlabelled</h4>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 essential for the process of developmentally controlled cell division that leads to sporulation. The biochemical function of Wbl proteins has been controversial; here, we set out to d ...[more]

WhiA and WhiB of Streptomyces venezuelae depend on each other for binding DNA

Project description: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 deletion background to show that the two proteins do indeed fail to bind DNA in the absence of one another.

Mutation of the cysteine residues that coordinate the WhiB [4Fe-4S] cluster prevents in vivo DNA binding by both WhiB and WhiA

Project description: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. ChIP-Seq using anti-FLAG anitbodies was performed in the following: 1. A whiB deletion strain expressing the FLAG-tagged serine version of WhiB (WhiBFLAG-Ser). 2. A whiB and whiA deletion strain expressing the FLAG-tagged serine version of WhiB (delAB_WhiBFLAG-Ser). 3. A whiB and whiA deletion strain expressing the serine version of WhiB and FLAG-tagged whiA (delAB_WhiAFLAG_WhiBcomp-Ser).

Determine whether Streptomyces venezuelae protein SepH (vnz_27360) binds DNA and where

Project description: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 to determine whether SepH specifically binds DNA and if so, where.

Identification by ChIP-Seq of the binding sites of the developmental protein WhiH in the genome of Streptomyces venezuelae

Project description:The whiH gene is required for the differentiation of aerial hyphae into spores in Streptomyces species. It is a predicted member of the GntR family of transcription factors and has been shown to bind specifically to a sequence in its own promoter. This ChIP-Seq experiment was carried out to determine all the binding sites whiH binds to in the genome of Streptomyces venezuelae. A whiH deletion strain was made and a FLAG tagged whiH protein was expressed in it from a genome-integrated plasmid. Then anti-FLAG antibodies were used for chromatin immunoprecipitation followed by high throughput sequencing. The wild type Streptomyces venezuelae strain (ATCC 10712) was used as a negative control. For both the FLAG-WhiH strain and the WT strain, non-immunoprecipitated (total) DNA was also sequenced to arrive at a background enrichment which could be subtracted from the enrichment in the immunoprecipated sample.

Identification by ChIP-Seq of the binding sites of the developmental protein BldC in the genome of Streptomyces venezuelae

Project description:The BldC gene is required for the formation of aerial hyphae Streptomyces venezuelae. It is 68 amino acid DNA-binding protein related to the MerR family of transcription factors. BldC deletion strains are bald because they initiate sporulation prematurely, omitting the formation of aerial hyphae altogether. This ChIP-Seq experiment was carried out to determine all the binding sites BldC binds to in the genome of Streptomyces venezuelae. Anti-BldC antibodies were used for ChIP-Seq of the wild type (WT) strain after 10 and 14 hours of growth in shaken cultures. A BldC deletion strain was made and anti-BldC antibodies were used for ChIP-Seq in the deletion strain after 14 hours of growth in shaken cultures. This was used as the negative control and enrichment in this ChIP-Seq was subtracted from the enrichment in the WT strain.

Identification by ChIP-Seq of the binding sites of the sigma factor WhiG in the genome of Streptomyces venezuelae

Project description:The WhiG sigma factor gene is required for spore formation is Streptomyces venezuelae. It is similar to the FliA sigma factor of E. coli. WhiG deletion strains are able to make aerial hyphae but are defective in the spore maturation. This ChIP-Seq experiment was carried out to determine all the binding sites WhiG binds to in the genome of Streptomyces venezuelae. Anti-WhiG polyclonal antibodies were used for ChIP-Seq of the wild type (WT) strain after 34 hours of growth in shaken cultures. A WhiG deletion strain was made and anti-WhiG antibodies were used for ChIP-Seq in the deletion strain after 34 hours of growth in shaken cultures. This was used as the negative control and ChIP-Seq peak positions in this were disregarded in the WT.

Project description:To determine the influence of BldM and WhiI on the binding of each other to their respective binding sites in the genome of Streptomyces venezuelae, ChIP-Seq experiments were carried out using polyclonal antibodies against the wild type proteins as well as anti-FLAG antibodies against FLAG-tagged proteins. Null mutants of Streptomyces venezuelae lacking WhiI or BldM were used as controls. The wild tpe strain was used as control in experiments using the anti-FLAG antibodies.

Project description:To examine the effects of cyclic-di-GMP on DNA binding by BldD in vivo, we manipulated the levels of c-di-GMP in Streptomyces venezuelae and monitored the effect on BldD binding to its target promoters in vivo by ChIP-seq, using a polyclonal BldD antibody. The degree of BldD binding was assayed at a single time point in wild-type (wt) S. venezuelae and the wt overexpressing either the diguanylate cyclase CdgB or the phosphodiesterase YhjH. A bldD null mutant was used a negative control.
