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.

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

Project description:Based on the chromosomal locations of genes inferred from sequence analysis to be essential for the viability of Streptomyces coelicolor, Bentley et al. (Bentley et al., 2002) have suggested that a 4.9 Mb central region of the linear S. coelicolor chromosome encodes core functions expressed during vegetative growth of this species, while 1.5 Mb and 2.3 Mb chromosomal DNA segments lateral to this core encode auxiliary functions proposed to be required under other growth conditions. To examine this hypothesis and experimentally identify genes expressed during vegetative growth of S. coelicolor cultures, we used DNA microarrays to measure globally the abundance of S. coelicolor transcripts in cells growing in liquid medium. We found that, overall, genes corresponding to the 4.9 Mb core region of the S. coelicolor M145 chromosome were more highly expressed under non-limiting growth conditions than genes in the 1.5 Mb left and 2.3 Mb right chromosome arms, supporting the notion of the core versus auxiliary organization of genes on the chromosome. To examine how this chromosomal distribution of transcripts changes under other growth conditions, we also measured gene expression changes during stationary phase and several stress conditions. During stationary phase, the composition of S. coelicolor transcripts appears to shift from large quantities of growth-related transcripts encoded in the core region to those of less characterized genes, which may be essential for differentiation and other physiological responses, encoded throughout the chromosome. After temperature and osmotic upshifts, we found that S. coelicolor transiently induces a set of several hundred genes located throughout the chromosome, which may function in response mechanisms common to the two stress conditions.

Project description:The Streptomyces coelicolor two genes operon SCO5784-SCO5785 encodes a two-component system which functions in a similar manner to that of the Bacillus subtilis DegS-DegU system. Propagation of the regulatory gene in high copy number results in the overproduction of several extracellular enzymes, among them the major extracellular protease, as well as in a higher level of synthesis of the antibiotic actinorhodin. This two-component system seems to control various processes characterised by the transition from primary to secondary metabolism in S. coelicolor, as determined by proteomic and transcriptomic analices. The presence of the regulatory gene in high copy number in S. coelicolor additionally seems to elicit a stringent response in the bacterial cell. Therefore, we propose renaming S. coelicolor genes SCO5784 and SCO5785 as degS and degU, respectively. All microarray analyses were performed with RNA samples obtained from three independent cultures grown under identical conditions. Hybridisation assays were carried out with cDNA obtained from RNA extracted at the late exponential phase of growth (24h). The transcriptional profile of wild type (S. coelicolor M145) cells carrying the multicopy plasmid pIJ487 was compared with that of the same strain carrying the degU gene cloned in the same plasmid under the control of its own promoter (S. coelicolor M28). And the transcriptional profile of wild type (S, coelicolor M145) cells was compared to that of the DegU deficient strain (S. coelicolor I32).
