Probing the protein inventory of the human pathogen Clostridium difficile

ABSTRACT: The anaerobic and spore-forming bacterium Clostridium difficile has turned into an intensively studied species which can be attributed to increasing numbers of infections and rising costs for the health care system. This dataset represents a benchmark proteome of reference strain C. difficile 630erm and provides mass spectrometry based details on identified proteins which was generally missing from hitherto published datasets. An elaborate annotation and visualization of the 3764 open reading frames will serve as a valuable base for researchers trying to evaluate results of global expression studies. Furthermore, protein expression of late exponentially growing cells in the complex medium BHI and in C. difficile minimal medium was compared. Whereas abundance of proteins of DNA metabolism, protein synthesis and cell envelope showed no variation, enzymes for the biosynthesis of some vitamins and purine as well as proteins involved in butanoate fermentation differed significantly depending on the growth medium.

Dynamic profiling of the protein life cycle in response to pathogens (protein)

Project description:Protein expression is regulated by production and degradation of mRNAs and proteins, but their specific relationships remain unknown. We combine measurements of protein production and degradation and mRNA dynamics to build a quantitative genomic model of the differential regulation of gene expression in LPS stimulated mouse dendritic cells. Changes in mRNA abundance play a dominant role in determining most dynamic fold changes in protein levels. Conversely, the preexisting proteome of proteins performing basic cellular functions is remodeled primarily through changes in protein production or degradation, accounting for over half of the absolute change in protein molecules in the cell. Thus, the proteome is regulated by transcriptional induction of novel cellular functions and remodeling of preexisting functions through the protein life cycle. Mouse primary dendritic cells were treated with LPS or mock stimulus and profiled over a 12-hour time course. Cells were grown in M-labeled SILAC media, which was replaced with H-labeled SILAC media at time 0. Aliquots were taken at 0, 0.5, 1, 2, 3, 4, 5, 6, 9, and 12 hours post-stimulation and added to equal volumes of a master mix of unlabeled (L) cells for the purpose of normalization. RNA-Seq was performed at 0, 1, 2, 4, 6, 9, and 12 hours post-stimulation.

Virulence induction in Pseudomonas aeruginosa under inorganic phosphate limitation: a proteomics perspective

Project description:Inorganic phosphate (Pi) is a central nutrient and signal molecule for bacteria. Pi limitation was shown to increase the virulence of a number of phylogenetically diverse pathogenic bacteria with different in lifestyles. Hypophosphatemia enhances the risk of death in patients due to general bacteremia and was observed after the surgical injury in humans and animals. Phosphate therapy, or the reduction of bacterial virulence by the administration of Pi or phosphate-containing compounds, is a promising anti-infective therapy approach that will not cause cytotoxicity nor the emergence of antibiotic-resistant strains. The proof of concept of phosphate therapy has been obtained using primarily Pseudomonas aeruginosa (PA) as a model. However, a detailed understanding of Pi-induced changes at protein levels is missing. Using pyocyanin production as proxy, we show that the Pi-mediated induction of virulence is a highly cooperative process that occurs between 0.2 to 0.6 mM Pi. We present a proteomics study of PA grown in minimal medium supplemented with either 0.2 or 1 mM Pi and rich medium. About half of the predicted PA proteins could be quantified. Among the 1,471 dysregulated proteins comparing growth in 0.2 mM to 1 mM Pi, 1100 were depleted under Pi-deficient conditions. Most of these proteins are involved in general and energy metabolism, different biosynthetic and catabolic routes, or transport. Pi depletion caused accumulation of proteins that belong to all major families of virulence factor categories, including pyocyanin synthesis, secretion systems, quorum sensing, chemosensory signaling and the secretion of proteases, phospholipases and phosphatases.

The in vivo responses elicited by Clostridium difficile in response to the gut commensal B. thetaiotaomicron and diet

Project description:Analysis of Clostridium difficile (Cd) from the cecal contents of germ-free mice or Bacteroides thetaiotaomicron (Bt)-monocolonized mice on a standard, polysaccharide rich diet or polysaccharide deficient diet 5 days after infection. Results identify genes that are involved in the Cd response to diet, in vivo colonization and in interactions with Bt. In vitro transcriptional profiles of Clostridium difficile obtained from cecal contents of germ-free or Bt-monocolonized mice on a standard, polysaccharide rich or polysaccharide deficient diet. 4 samples/group. 2 control genomic DNA samples for Clostridium difficile and 2 reference genomic DNA samples for Bacteroides thetaiotaomicron Please note that 4 control samples (genomic DNA) were used to determine whether the genomic DNA correctly bound to the probes and thus, were not included in data processing (i.e no processed/normalized data).

A metabolic labeling strategy for relative protein quantification in Clostridioides difficile

Project description:Clostridioides difficile (formerly Clostridium difficile) is a Gram-positive, spore-forming pathogen which cases drug-induced Clostridioides difficile-associated diseases in hospitals worldwide. A detailed analysis of the proteome may provide new targets for drug development or therapy strategies to combat this pathogen. So far, quantitative proteome analyses could only be carried out by label-free or chemical labeling methods. However, the application of metabolic labeling would allow for accurate quantification of significant differences, even in the case of very small changes. Additionally, it would be possible to perform bias free studies of the membrane or surface proteome which require elaborated preparations and are therefore prone to higher standard deviations during the quantification. Up to now, the implementation of metabolic labeling strategies of C. difficile was hampered by the very specific metabolic requirements of this anaerobic pathogen. To solve this problem, media were evaluated and the cultivation procedure with 15N labeled media for the C. difficile 630Δerm strain was optimized to gain a high incorporation rate. In the following proof-of-principle experiment, the cytosolic sub-proteomes of C. difficile cells of three different cultivation media and two growth phases were analyzed resulting in reproducible data which are shown in detail.

Escherichia coli can adapt its protein translocation machinery for enhanced periplasmic recombinant protein production

Project description:Recently, we engineered a tunable rhamnose promoter-based setup for the production of recombinant proteins in E. coli. This setup enabled us to show that being able to precisely set the production rate of a secretory recombinant protein is critical to enhance protein production yields in the periplasm. It is assumed that precisely setting the production rate of a secretory recombinant protein is required to harmonize its production rate with the protein translocation capacity of the cell. Here, using proteome analysis we show that enhancing periplasmic production of human Growth Hormone (hGH) using the tunable rhamnose promoter-based setup is accompanied by increased accumulation levels of at least three key players in protein translocation; the peripheral motor of the Sec-translocon SecA, leader peptidase (LepB) and the cytoplasmic membrane protein integrase/chaperone YidC. Thus, enhancing periplasmic hGH production leads to increased Sec-translocon capacity, increased capacity to cleave signal peptides from secretory proteins and an increased capacity of an alternative membrane protein biogenesis pathway, which frees up Sec-translocon capacity for protein secretion. When cells with enhanced periplasmic hGH production yields were harvested and subsequently cultured in the absence of inducer, SecA, LepB and YidC levels went down again. This indicates that when using the tunable rhamnose-promoter system to enhance the production of a protein in the periplasm, E. coli can adapt its protein translocation machinery for enhanced recombinant protein production in the periplasm.

Differential view on the bile acids stress response of Clostridioides difficile_longterm stress

Project description:In this study, we aimed at the characterization of C. difficile’s stress response to the main four human bile acids. Although, a phenotypically description of growth differences upon challenge with different bile acids has been described (Lewis 2016, Thanissery 2017), there is no information on the adaptation of gene expression available. We employed a comprehensive proteomics approach to record stress signatures of the unconjugated bile acids CA, CDCA, DCA and LCA during long-term-stress conditions and could depict a general stress response concerning all four bile acids, but also specific responses to only a single or a few of the different bile acids. Our results are a starting point for the understanding of how the individual bile acids cocktail of a patient can decide on the outcome of a C. difficile infection

Hfq is involved in global protein expression and stress response in Bordetella pertussis

Project description:In this study, we used gel-free nanoLC-MS/MS-based proteomics to compare the protein profile of B. pertussis wild type and an isogenic hfq defective mutant strain under control an iron limited conditions. We found that Hfq affects the abundance of 302 proteins, which represents 8% of the total B. pertussis coding sequence. The absence of Hfq induced changes in the abundance of proteins involved in metabolic pathways, stress response and virulence. Hfq was also found involved in B. pertussis adaptation to iron starvation, one of the main stresses this pathogen faces inside the host. Altogether, these results indicate that B. pertussis Hfq is involved in bacterial physiological processes as well as bacterial pathogenesis.

A redirected protein secretion stress response in the genome-engineered midiBacillus-II

Project description:Genome engineering offers the possibility to create completely novel cell factories with enhanced properties for biotechnological application. In recent years, the possibilities for genome engineering have been extensively explored in the Gram-positive bacterial cell factory Bacillus subtilis, where up to 42% of the genome, encoding dispensable functions has been removed. Such studies have shown that some strains with minimized genomes gained beneficial features, for instance in protein production. However, strains with the most minimal genomes also showed particular growth defects. This has focused our attention on strains with less extensive genome deletions that show close-to-wild-type growth properties, while retaining the acquired beneficial traits in secretory protein production of strains lacking larger genomic segments. A strain of the latter category is B. subtilis IIG-Bs27-47-24, here referred to as midiBacillus II, which lacks 30.95% of the parental genome. To date, it was unknown how the altered genomic configuration of midiBacillus II impacts on cell physiology at large, and protein secretion in particular. Therefore, the present study was aimed at bridging this knowledge gap through an in-depth proteomics analysis with special focus on protein secretion stress responses. Interestingly, the results show that the secretion stress response of midiBacillus II as elicited by high-level expression of a staphylococcal antigen is completely different from the secretion stress responses that occur in the parental strain 168. This implies that high-level protein secretion has different implications for wild-type and genome-engineered Bacillus strains, dictated by the altered genomic and proteomic configurations.
