Project description:Using Mycoplasma pneumoniae as a model organism, we conditionally depleted the two essential ATP-dependent proteases (Lon and FtsH) of this bacterium, by engineering three strains carrying a Lon and/or FtsH inducible expression locus. An integrative comparative study combining label-free shotgun proteomics and RNA-seq allowed us to decipher the global cellular response to Lon and FtsH depletion and to define protease substrates in this genome-reduced organism.
Project description:RNA-seq was performed in this study in order to identify whether the introduction of a gene mutation in S. pneumoniae, has any effect increase or decrease expression of any S. pneumoniae genes in the mutant strains that previous publications suggest might affect the safe use of these strains in humans.

Project description:Investigation of whole genome gene expression level changes in S. pneumoniae KCTC 5080T, S. mitis KCTC 3556T, S. oralis KCTC 13048T, and S. pseudopneumoniae CCUG 49455T. This proves that transcriptional profiling can facilitate in elucidating the genetic distance between closely related strains. A one chip study using total RNA recovered from S. pseudopneumoniae CCUG 49455T with three strain. For the the transcriptome of S. pseudopneumoniae CCUG 49455T was analyzed using the S. pneumoniae R6 microarray platform and compared with those of S. pneumoniae KCTC 5080T, S. mitis KCTC 3556T, and S. oralis KCTC 13048T strains.

Project description:The Antibiotic Resistant Sepsis Pathogens Framework Initiative aims to develop a framework dataset of 5 sepsis pathogens (Escherichia coli, Klebsiella pneumoniae complex, Staphylococcus aureus, Streptococcus pneumoniae and Streptococcus pyogenes, 5 strains each) using an integrated application of genomic, transcriptomic, metabolomic and proteomic technologies. This submission contains the results from five Streptococcus pneumoniae strains (4496, 947, 4559, 180-2, 180-15) grown under three conditions: RPMI supplemented with glucose, RPMI supplemented with galactose, or pooled human sera. Six replicates of each condition were subjected to shotgun proteomics and label-free MS1-based quantitation.

An integrative comparative study combining label-free shotgun proteomics and RNA-seq allowed us to decipher the global cellular response to Lon and FtsH depletion and to define protease substrates in this genome-reduced organism. This particular dataset corresponds to the analysis of the Triton X-100 insoluble fractions of Lon and FtsH mutants grown under inducing and depleting conditions. The dataset for the whole cell lysate is available under the identifier PXD016343.
