Project description:Transcriptional profile of Streptococcus pyogenes stk mutant strain JRS2516 vs its wild type parent strain MGAS2221 The RNA prepared from triplicate cultures for the wild type and the stk mutant strains was each labeled with Cy3 and hybridized to duplicate arrays. Reference RNA consisted of pooled RNA for the wild type and stk mutant, labeled with Cy5.

Project description:Streptococcus pyogenes (Group A streptococcus, GAS) is an important human pathogen that causes a variety of infectious diseases and sequelae. Recent studies showed virulence factor expression was controlled at multiple levels, including the post-transcriptional regulation. In this study, we examined the global half-lives of S. pyogenes mRNAs and explored the role RNase Y played in mRNA metabolism with microarray analysis. key word: genetic modification

Project description:The proteome and phosphoproteome of Streptococcus pyogenes M49 was investigated at different growth phases of cultures grown in either rich medium (THY), chemically defined medium without carbon source, or chemically defined medium containing 1% fructose. Of the 815 phosphosites identified, 463 were included in a label-free quantitative analysis of dynamic protein phosphorylation. A small group of phosphorylation events, almost exclusively at threonine residues, was strongest during growth and decreased during stationary phase. These included phosphorylation sites of the PASTA kinase SP-STK and its putative substrates suggesting that the PASTA kinase-dependent processes regulating the cell cycle in related bacteria are also conserved in S. pyogenes. Most phosphorylation events occurred preferentially at serine residues in the stationary growth phase and under starvation conditions. The elucidation of the physiological significance and the responsible kinases of these phosphorylations require further investigations. In addition to phosphorylation events at S/T/Y residues, phosphoglycerylation of lysine (PGK) occurred frequently among the enriched phosphopeptides.

In this study, we examined the global half-lives of S. pyogenes mRNAs and explored the role RNase Y played in mRNA metabolism with microarray analysis. key word: genetic modification Streptococcus pyogenes NZ131 wild-type cells and ?rny strains were grown in C-medium until late exponential phase. Rifampicin was added to the cell culture and samples were collected before and after rifampicin addition. The transcriptional profile of the whole genome before and after rifampicin addition was examined with microarray. Please note that mRNA decay assay resulted in considerable variations in the datasets. Samples were taken after rifampicin addition and subsequent incubation for different time intervals. During that time no new RNA is produced and the remaining RNA is degraded to various degrees.

Project description:The Antibiotic Resistant Sepsis Pathogens Framework Initiative aims to develop a framework dataset of 5 sepsis pathogens (5 strains each) using an integrated application of genomic, transcriptomic, metabolomic and proteomic technologies. The pathogens included in this initiative are: Escherichia coli, Klebsiella pneumoniae complex, Staphylococcus aureus, Streptococcus pyogenes, and Streptococcus pneumoniae. This submission pertains to Streptococcus pyogenes strains 5448, SP444, HKU419, PS003 and PS006.
