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).
Project description:This study compared the genome of Streptomyces rimosus rimosus against that of Streptomyces coelicolor. It also compared 4 strains with changes in oxytetracycline production and derived from G7, the type strain, against G7. Keywords: Comparative genomic hybridization
Project description:We performed ribosome profiling which is the deep-sequencing of mRNA fragments protected by translating ribosome for two Streptomyces species through different growth phases to provide the translatome data
Project description:Cervimycins A‒D are natural products of Streptomyces tendae HKI 0179 with promising activity against multidrug resistant staphylococci and vancomycin resistant enterococci. To initiate mode of action studies, we selected cervimycin C and D resistant (CmR) Staphylococcus aureus strains. Genome sequencing of CmR mutants revealed amino acid exchanges in the essential histidine kinase WalK, the Clp protease proteolytic subunit ClpP or the Clp ATPase ClpC, and the heat shock protein DnaK. Proteomic analysis revealed massive alterations in CmR-02 (amino acid exchanges: ClpP-I29F, DnaK-A112P, WalK-A243V) compared to the parent strain S. aureus SG511 Berlin, with major modifications in the heat shock regulon, the metal ion homeostasis and the carbohydrate metabolism. These effects were alleviated in the antibiotic susceptible suppressor mutant 02REV (amino acid exchanges: ClpP-I29F/M31I, WalK-A243V/S191L).
