Proteomic analysis of Streptomyces coelicolor vesicles

Project description:Streptomyces coelicolor is a model organism for the study of Streptomyces, a genus of Gram-positive bacteria that undergoes a complex life cycle and produces an enormous repertoire of bioactive metabolites and extracellular enzymes. This study investigated the production and characterization of membrane vesicles (MVs) in liquid cultures of S. coelicolor M145 from a structural and biochemical point of view using microscopic, physical and -omics analyzes. Two main populations of MVs, F3 and F4 MVs, with different size and cargo were isolated and purified. S. coelicolor MV cargo is complex and contains many “messages” such as proteins and metabolites. A total of 166 proteins involved in cell metabolism and differentiation, molecular processing and transport was identified in MVs. In particular, a subset of these proteins was protected from the degradation after proteinase K treatment, indicating their localization inside the vesicles. Vesicle proteome includes many stress response proteins which also play an important role in S. coelicolor morpho- physiological differentiation. Moreover, MVs packaged with an array of metabolites such as antibiotics, vitamins, amino acids and components of carbon metabolism. The analysis of S. coelicolor MV cargo will provide informations to elucidate their biogenesis and functions

Genome-wide binding site profiling of NdgR in Streptomyces coelicolor

Project description:We identified genome-wide binding regions of NdgR in Streptomyces coelicolor using chromatin immunoprecipitation sequencing (ChIP-seq). We constructed 6×myc-tagged NdgR strain using homologous recombination with myc-tagging vector. Analysis of the sequencing data aligned to Streptomyces coelicolor genome database (NC_003888).

Evidence of a role for CutRS and actinorhodin in the secretion stress response in Streptomyces coelicolor M145

Project description:This work was carried out to elucidate the proteins that are regulated by the two-component system CutRS in Streptomyces coelicolor M145 and how this response changes in the presence of glucose. A comparison of the whole cell proteomes of Streptomyces coelicolor M145 WT and Streptomyces coelicolor M145 ∆cutRS on both DNA (no glucose) and DNAD (with glucose) was made.

Strand-specific RNA-seq analysis of three streptomycetes

Project description:We report the mRNA and small RNA transcriptomes of Streptomyces coelicolor, Streptomyces avermitilis, and Streptomyces venezuelae. We identified dozens of new conserved sRNAs and antisense RNAs, including a prominent group of antisense RNAs termed ‘cutoRNAs’ that result from overlap of the 3′ ends of convergently transcribed mRNAs. In addition, we observed abundant unique ncRNAs, including many within secondary metabolic gene clusters.
