The centromeric nucleosome of budding yeast is perfectly positioned and covers the entire centromere.

The centromeres of budding yeast are ~120 bp in size and contain three functional elements: an AT-rich region flanked by binding sites for Cbf1 and CBF3. A specialized nucleosome containing the H3 variant Cse4 (CenH3) is formed at the centromere. Our genome-wide paired-end sequencing of nucleosomal DNA reveals that the centromeric nucleosome contains a micrococcal nuclease-resistant kernel of 123-135 bp, depending on the centromere, and is therefore significantly shorter than the canonical nucle ...[more]

Novel nucleosomal particles containing core histones and linker DNA but no histone H1

Project description:The nucleosome plays a central role in genome regulation. Traditional methods for mapping nucleosomes depend on the resistance of the nucleosome core to micrococcal nuclease (MNase). However, the lengths of the protected DNA fragments are heterogeneous, limiting the accuracy of nucleosome position information. To resolve this problem, we removed residual linker DNA by simultaneous digestion of yeast chromatin with MNase and exonuclease III (ExoIII). Paired-end sequencing of mono-nucleosomes revealed not only core particles (145-147 bp), but also intermediate particles in which ~8 bp project from one side (154 bp) or both sides (161 bp) of the nucleosome core. We term these particles "pseudo-chromatosomes" because they are present in yeast lacking linker histone. They are also observed after MNase-ExoIII digestion of chromatin reconstituted using recombinant core histones. We propose that the pseudo-chromatosome provides a DNA framework to facilitate H1 binding. Comparison of budding yeast nucleosome sequences obtained using micrococcal nuclease (MNase-seq) and MNase + exonuclease III (ExoIII) (MNase-ExoIII-seq): wild type cells and hho1-null cells. Nucleosome sequences from native chromatin and H1-depleted chromatin from mouse liver. Nucleosome sequences from a plasmid reconstituted into nucleosomes using recombinant yeast histones or native chicken erythrocyte histones.

Genome-wide cooperation by HAT Gcn5, remodeler SWI/SNF, and chaperone Ydj1 in promoter nucleosome eviction and transcriptional activation

Project description:Chaperones, nucleosome remodeling complexes and histone acetyltransferases have been implicated in nucleosome disassembly at promoters of particular yeast genes, but whether these co-factors function ubiquitously, and the impact of nucleosome eviction on transcription genome-wide, are poorly understood. We used chromatin immunoprecipitation of histone H3 and RNA polymerase II (Pol II) in mutants lacking single or multiple co-factors to address these issues for ~200 genes belonging to the Gcn4 transcriptome, of which ~70 exhibit marked reductions in H3 promoter occupancy on induction by amino acid starvation. Examining four target genes in a panel of mutants indicated that SWI/SNF, Gcn5, the Hsp70 co-chaperone Ydj1, and chromatin-associated factor Yta7 are required downstream of Gcn4 binding for robust H3 eviction in otherwise wild-type cells. Using ChIP-seq to interrogate all 70 exemplar genes in single, double and triple mutants implicated Gcn5, Snf2 and Ydj1 in H3 eviction at most, but not all Gcn4 target promoters, with Gcn5 generally playing the greatest role and Ydj1 the least. Remarkably, these 3 co-factors cooperate similarly in H3 eviction at virtually all yeast promoters. Defective H3 eviction in co-factor mutants was coupled with reduced Pol II occupancies for the Gcn4 transcriptome and the most highly expressed uninduced genes, but the relative Pol II levels at most genes were unaffected or even elevated. These findings indicate that nucleosome eviction is crucial for robust transcription of highly expressed genes, but that other steps in gene activation are more rate-limiting for most other yeast genes. Chromatin immunoprecipitated DNA from WT (induced(+SM) and uninduced(no SM)) and mutants (induced(+SM)) followed by paired-end sequencing. Nucleosomal DNA obtained by MNase digestion were also subjected to paired-end sequencing.

The ISW1 and CHD1 ATP-dependent chromatin remodelers compete to set nucleosome spacing in vivo

Comparison of budding yeast nucleosome positions obtained using micrococcal nuclease digestion followed by paired-end sequencing (MNase-seq). We sequenced nucleosomes from isogenic strains with the isw1Î, isw2Î or chd1Î mutations in all combinations. We measured gene activity by ChIP-seq for the Rpb3 subunit of RNA polymerase II for some of these mutants.

Nucleosome positioning for 4 yeast species

Project description:We describe the genome-wide nucleosome profiles of four related yeast species. All species display the same global organization features first described in S. cerevisiae: a stereotypical nucleosome organization along genes, and the classification of promoters into these which contain or lack a pronounced Nucleosome Depleted region (NDR), with the latter displaying a more dynamic pattern of gene expression. This global similarity, however, does not reflect a static evolutionary pattern, as nucleosome positioning at specific genes diverged rapidly leaving practically no similarity between S. cerevisiae and C. glabrata orthologs (~50 Myr). We show that this rapid divergence in nucleosome positioning contrasts a conserved pattern of gene expression, consistent with the idea that divergence of nucleosome patterns has a limited effect on gene expression as many different configurations can support the same regulatory outcome. Nucleosomes from 4 different yeast species were isolated and sequenced using the Illumina GAII platform. Replicates were performed for 3 of the species

MNase-Seq of isolated mono-nucleosomes from strains W303 (wild-type) and htz1∆.

Project description:Chromatin transactions are typically studied in vivo, or in vitro using artificial chromatin lacking the epigenetic complexity of the natural material. Attempting to bridge the gap between these approaches, we established a system for isolating the yeast genome as a library of mono-nucleosomes harbouring the natural epigenetic signature, suitable for biochemical manipulation. Combined with deep sequencing, this library was used to investigate the stability of individual nucleosomes, and – as proof of principle - the nucleosome preference of the chromatin remodeling complex, RSC. In order to generate a library of native yeast nucleosomes, we developed a three-step purification protocol: first, purified yeast nuclei were incubated with micrococcal nuclease (MNase), which preferentially digests naked DNA to generate short chromatin fragments. The resulting fragments were extracted from the nuclei, then bound to and eluted from DEAE sepharose. This was followed by ultracentrifugation through a sucrose gradient to separate the fragments by length to further remove contaminating proteins and free DNA. We chose a simple disassembly assay, which involves incubating the nucleosome library with ATP and the histone chaperone Nap1, with or without RSC. In this assay, RSC binds to nucleosomes and transfers the histones to Nap1, thereby releasing ‘naked’ DNA. Under certain conditions, reaction intermediates can be observed (tetramers or hexasomes), but for simplicity we chose to compare the input nucleosomes with the final naked DNA product. To separate the RSC-dependent released DNA from the non-remodeled nucleosomes, the reactions were subjected to native agarose gel electrophoresis, and DNA of the four bands isolated by gel-extraction. The upper bands, harboring nucleosomes, were named NUC (no RSC) and NUCR (with RSC), whereas the lower, ‘naked’ DNA bands were named DNA (no RSC) and DNAR (with RSC).
