Transcriptome analysis of E.coli MG1655 under multiple growth conditions

ABSTRACT: Investigation of comprehensive information about the expression level of RNA transcripts across the entire E.coli genome in mulitple growth conditions, including log-phase; stationary phase, heat shock and nitrogen-limiting condition. A fourteen chip study using total RNA recovered from four separate culture conditions of E.coli K12 MG1655. E.coli strains were harvested at mid-exponential phase with exception of stationary phase experiments. The high-density oligonucleotide tiling arrays used were consisted of 371,034 oligonucleotide probes spaced 25 bp apart (25-bp overlap between two probes) across the E. coli genome (NimbleGen). Experiments were conducted as three or more biological replicates (different cultures)

Bacterial genomes are organized by structural and functional elements, including promoters, transcription start and termination sites, open reading frames, regulatory noncoding regions, untranslated regions and transcription units. Here, we iteratively integrate high-throughput, genome-wide measurements of RNA polymerase binding locations and mRNA transcript abundance, 5' sequences and translation into proteins to determine the organizational structure of the Escherichia coli K-12 MG1655 genome. ...[more]

ChIP-chip of MG1655 with antibody against E. coli RNAP beta subunit under various conditions

Project description:We integrated RNAP binding regions (RBRs) and mRNA transcript abundance to determine segments of contiguous transcription originating from promoter regions. To measure RBRs at a genome scale, we employed a ChIP-chip method to E. coli K-12 MG1655 grown in the presence or absence of rifampicin under multiple growth conditions using antibody against E. coli RNAP beta subunit. A twelve ChIP-chip study using immunoprecipitated DNA (IP-DNA) from four separate culture conditions with and/or without rifampicin treatment. The high-density oligonucleotide tiling arrays used were consisted of 371,034 oligonucleotide probes spaced 25 bp apart (25-bp overlap between two probes) across the E. coli genome (NimbleGen). Experiments were conducted as biological duplicates or triplicates (different cultures).

Proteome dynamics in persisting and resuscitating bacterial cells

Project description:Bacterial persister cells become transiently tolerant to antibiotics by restraining their growth and metabolic activity. Detailed molecular characterization of bacterial persistence is hindered by low count of persisting cells and the need for their isolation. Here we used sustained addition of stable isotope-labeled lysine to selectively label the proteome of hipA-induced persisting and hipB-induced resuscitating E. coli cells in minimal medium after antibiotic treatment. Time-resolved, 24-hour measurement of label incorporation allowed detection of more than 500 newly synthetized proteins in persister cells, demonstrating low but widespread protein synthesis during persistence. Many essential proteins were newly synthesized; several ribosome-associated proteins showed unusually high synthesis levels and are involved in maintenance of persistence. At the onset of resuscitation, cells synthesized ABC transporters, restored translation machinery and resumed metabolism by inducing glycolysis and biosynthesis of amino acids. This dataset provides an unprecedented insight into the processes governing persistence and resuscitation of bacterial cells.

Fermentative and nitrate respiratory transcriptome analysis of E. coli K12 MG1655

Project description:Determining how facultative anaerobic organisms sense and direct cellular responses to electron acceptor availability has been a subject of intense study. However, even in the model organism Escherichia coli, established mechanisms only explain a small fraction of the hundreds of genes that are regulated during shifts in electron acceptor availability. Here we propose a qualitative model that accounts for the full breadth of regulated genes by detailing how two global transcription factors (TFs), ArcA and Fnr of E. coli, sense key metabolic redox ratios and act on a genome-wide basis to regulate anabolic, catabolic, and energy generation pathways. We first fill gaps in our knowledge of this transcriptional regulatory network by carrying out ChIP-chip and gene expression experiments to identify 463 regulatory events. We then interfaced this reconstructed regulatory network with a highly curated genome-scale metabolic model to show that ArcA and Fnr regulate > 80% of total metabolic flux and 96% of differential gene expression across fermentative and nitrate respiratory conditions. Finally, based on the data we propose a feedforward with feedback trim regulatory scheme by showing extensive repression of catabolic genes by ArcA and extensive activation of chemiosmotic genes by Fnr. We further corroborated this regulatory scheme by showing a 0.71 r2 (p < 1e-6) correlation between changes in metabolic flux and changes in regulatory activity across fermentative and nitrate respiratory conditions. We also are able to relate the proposed model to a wealth of previously generated data by contextualizing the existing transcriptional regulatory network. Biological replicates were performed in triplicate for M-NM-^Tfnr, M-NM-^TarcA, and wild type Escherichia coli K12 MG1655 strains under both fully fermentative and nitrate respiratory conditions. An 18 chip study with three different strains under two different culture conditions.

On the mechanism and origin of isoleucyl-tRNA synthetase editing against norvaline

Project description:Aminoacyl-tRNA synthetases (aaRSs), the enzymes responsible for coupling tRNAs to their cognate amino acids, minimize translational errors by intrinsic hydrolytic editing. Here, we compared the propensity of norvaline (Nva), a linear amino acid not coded for protein synthesis, to the proteinogenic, branched valine (Val) to mistranslate isoleucine (Ile) in proteins. We show that in the synthetic site of isoleucyl-tRNA synthetase (IleRS), aminoacylation and pre-transfer editing with Nva and Val occur at similar rates. Post-transfer editing was, however, more efficient with Nva as IleRS misaminoacylates Nva-tRNAIle at slower rate than Val-tRNAIle. Accordingly, an Escherichia coli strain lacking IleRS post-transfer editing misincorporated Nva and Val in the proteome to a similar extent and at the same Ile positions. However, Nva mistranslation inflicted higher toxicity than Val, in agreement with IleRS post-transfer editing domain being optimized for hydrolysis of Nva-tRNAIle. Furthermore, we found that the evolutionary related IleRS, leucyl- and valyl-tRNA synthetases (I/L/VRSs), all efficiently hydrolyze Nva-tRNAs even when editing of Nva seems redundant. Thus, we hypothesize that editing of Nva-tRNAs had already existed in the last common ancestor of I/L/VRSs, and that the editing domain of I/L/VRSs had primarily evolved to prevent infiltration of Nva into modern proteins.

Transcriptional pattern of E. coli BW25113 and its ptsA, glpK and dhaKLM isogenic mutants growing on DHA (dihydroxyacetone).

Project description:Dihydroxyacetone (DHA) is an attractive molecule produced in a wide range of industries . DHA is found among all the kingdoms as an intermediate of various metabolic pathways and can be used as a carbon source by many organisms. The bacterium Escherichia coli is able to grow on DHA as the sole carbon source albeit at a low growth rate (0.1 h-1). If the topology of DHA metabolic network has been characterized, the function and regulation of the metabolic pathways involved in DHA metabolism remain unsolved. Here, we aimed to better understand DHA metabolism in E. coli BW25113 by exploring its transcriptional pattern on DHA versus glucose. We also studied the pattern of three DHA pathway mutants (dhaKLM, ptsA and glpK).

Effect of enzyme IIANtr on gene expression in Escherichia coli

Project description:Enzyme IIANtr (encoded by ptsN gene) is a component of the nitrogen phosphotransferase system (PTS). It has previously been shown that the dephosphorylated form of EIIANtr is required for the derepression of ilvBN encoding acetohydroxy acid synthase I (AHAS I) catalyzing the first step common to biosynthesis of branched-chain amino acids. Here we examine the effect of deletion of ptsN gene on global gene expression by microarray analysis. Most of the genes down-regulated in a ptsN mutant are controlled by sigma 70, while all the up-regulated genes are controlled by sigma S. As intracellular levels of sigma factors in the ptsN mutant were similar to those of the wild-type strain, this implied that the balance of sigma activities is modified by ptsN deletion. The E. coli K12 strain MG1655 and its isogenic ptsN mutant were used in all experiments. Overnight bacterial cultures were incubated in M9 minimal medium containing 0.5% glucose as carbon source. Cells from duplicate experiments were harvested in exponential growth phase when cultures reached an A600 of 0.4. RNA was extracted from each sample using a QIAGEN RNA extraction kit according to the manufacturer's instruction.

Differential proteome analysis of Escherichia coli grown on acetate vs. glucose

Project description:Relative protein abundances of Escherichia coli growing exponentially on minimal medium with acetate or glucose as the sole carbon source were investigated in a quantitative shotgun proteome analysis with TMT6-plex isobaric tags. Peptides were separated by high resolution high/low pH 2D-LC, using an optimized fraction pooling scheme followed by mass spectrometric analysis. Quantitative data were acquired for 1,994 proteins covering 46 % of the predicted E. coli proteins and 361 differentially abundant proteins were discovered. Differences in protein abundance were observed for proteins in central carbon metabolism, in particular for proteins involved in TCA cycle and glyoxylate shunt, fatty acid metabolism, glycolysis/gluconeogenesis and anaplerotic pathways. Significant changes were observed in proteins relevant for amino acid and protein synthesis, proteins necessary to process environmental information and scavenge for a variety of alternate carbon sources.
