Transcriptome and translatome landscape of Streptomyces coelicolor M145

Project description:We have integrated nucleotide resolution genome-scale measurements of the transcriptome and translatome of the Streptomyces coelicolor A3(2), the model antibiotic-producing actinomycete. Our systematic study determined 3,473 transcription start sites, leading to discovery of a high proportion (~21%) of leaderless mRNAs and 230 non-coding RNAs; this enabled deduction of promoter architecture on a genome-scale. Ribosome profiling analysis revealed that the translation efficiency was negatively correlated for secondary metabolic genes. These results provide novel fundamental insights into translational regulation of secondary metabolism that enables rational synthetic biology approaches to awaken such âsilentâ secondary metabolic pathways. Profiles of primary transcripts, whole transcripts, and ribosome protected fragments (RPFs) of Streptomyces coelicolor were generated by deep sequencing using Illumina Miseq.

Ribosome hibernation factor promotes Staphyloccocal survival and differentially represses translation

Project description:We sequenced a total of 16 cDNA libararies derived from fragmented total mRNA and ribosome protected mRNAs from S. aureus hpf mutant (NE838) and its parental strain JE2 grown in tryptic soy broth (TSB) or minimal medium (MM). The data represented 2 independent biological replicates. Examination of the impact of hpf on global S.aureus translatome, mRNA abundance and the ribosome density along the transcripts.

Human Hematopoietic Stem Cell Vulnerability to Ferroptosis [Ribosome profiling]

Project description:To investigate the translatome change due to loss of MYSM1 in CD34+CD45RA-CD90+ cells We performed ribosome profiling followed by NGS sequencing where only ribosome protected RNA was extracted to make the library, which mostly are in active translation

A spectral analysis approach to detects actively translated open reading frames in high resolution ribosome profiling data

Project description:RNA sequencing protocols allow for quantifying gene expression regulation at each individual step, from transcription to protein synthesis. Ribosome Profiling (Ribo-seq) maps the positions of translating ribosomes over the entire transcriptome. Despite its great potential, a rigorous statistical approach to identify translated regions from Ribo-seq data is not yet available. To fill this gap, we developed RiboTaper, which quantifies the significance of the three-nucleotide periodicity of Ribo-seq reads via spectral analysis methods. Examination of RNA fragments protected by ribosome

Ribosome pausing at the AT-rich codons regulates the protein expression of secondary metabolite gene clusters in the Streptomyces tsukubaensis NRRL 18488

Project description:Streptomyces tsukubaensis NRRL 18488 is the preferred strain for the production of immunosuppressant agent tacrolimus (FK506). To take full advantage of its genetic potential, systematic understanding of secondary metabolism and related regulatory mechanisms is highly demanded. Here, to this end, we complete its 7.9 Mbp linear genome sequence followed by integrating with multi-omics measurements. With accurate reannotation of FK506 gene cluster, total 2,389 transcription start sites were determined by using primary transcriptome analysis. Integrated analysis of transcriptome and translatome data revealed that secondary metabolic gene clusters, especially FK506 cluster, undergo translational control with decrease in translational efficiency according to the growth. Furthermore, we demonstrated that SD motif has little correlation with ribosome pausing but AT-rich codons delay the translational elongation. Strong ribosome pausing was observed in the rare TTA codon in FK506 cluster. This comprehensive genome-scale analysis provides insight to the translational regulation of secondary metabolism in S. tsukubaensis.

Transcriptional changes over time in exploring cultures of Streptomyces venezuelae

Project description:We isolated and sequenced mRNA from Streptomyces venezuelae grown on two different solid media that promote exploratory behaviour in this bacterial species. The data was analyzed using DeSeq2 to identify genes that undergo changes in expression over time as well as differences in gene expression patterns between the two media conditions.

Distinct stages of the translation elongation cycle revealed by sequencing ribosome-protected mRNA fragments

Project description:During translation elongation, the ribosome ratchets along its mRNA template, incorporating each new amino acid and translocating from one codon to the next. The elongation cycle requires dramatic structural rearrangements of the ribosome. We show here that deep sequencing of ribosome-protected mRNA fragments reveals not only the position of each ribosome but also, unexpectedly, its particular stage of the elongation cycle. Sequencing reveals two distinct populations of ribosome footprints, 28-30 nucleotides and 20-22 nucleotides long, representing translating ribosomes in distinct states, differentially stabilized by specific elongation inhibitors. We find that the balance of small and large footprints varies by codon and is correlated with translation speed. The ability to visualize conformational changes in the ribosome during elongation, at single-codon resolution, provides a new way to study the detailed kinetics of translation and a new probe with which to identify the factors that affect each step in the elongation cycle. Ribosome profiling, or sequencing of ribosome-protected mRNA fragments, in yeast. We assay ribosome footprint sizes and positions in three conditions: untreated yeast (3 replicates) and yeast treated with translation inhibitors cycloheximide (2 replicates) and anisomycin (2 biological replicates, one technical replicate). We also treat yeast with 3-aminotriazole to measure the effect of limited histidine tRNAs on ribosome footprint size and distribution (two treatment durations).
