Enteropathogenic and enterohaemorrhagic Escherichia coli are related pathotypes of bacteria that cause acute watery diarrhoea and haemorrhagic colitis, respectively, and enterohaemorrhagic E. coli can lead to a serious complication known as haemolytic uraemic syndrome. In both bacteria the global regulatory protein Ler controls virulence. The ler gene is found within the locus of enterocyte effacement, or LEE, encoding a type III secretion system necessary for injecting effector proteins into intestinal epithelial cells and causing net secretory diarrhoea. The nucleoid-associated protein H-NS silences, whereas Ler serves as an anti-silencer of, multiple LEE operons. Although Ler has a higher affinity for DNA than does H-NS, the precise molecular mechanism by which Ler increases LEE transcription remains to be determined. In this report we investigate the oligomerization activity of Ler. In solution, Ler forms dimers and soluble aggregates of up to 5000 kDa molecular mass, and appears to oligomerize more
TY - JOUR. T1 - A gram-negative characteristic segment in Escherichia coli DnaK is essential for the ATP-dependent cooperative function with the co-chaperones DnaJ and GrpE. AU - Sugimoto, Shinya. AU - Higashi, Chihana. AU - Saruwatari, Kozue. AU - Nakayama, Jiro. AU - Sonomoto, Kenji. PY - 2007/6/26. Y1 - 2007/6/26. N2 - We describe importance of the characteristic segment in ATPase domain of DnaK chaperone which is present in all gram-negative bacteria but is absent in all gram-positive bacteria. In vitro studies, ATPase activity, luciferase-refolding activity, and surface plasmon resonance analyses, demonstrated that a segment-deletion mutant DnaKΔ74-96 became defective in the cooperation with the co-chaperones DnaJ and GrpE. In addition, in vivo complementation assay showed that expression of DnaKΔ74-96 could not rescue the viability of Escherichia coli ΔdnaK mutant at 43 °C. Consequently, we suggest evolutionary significance for this DnaK ATPase domain segment in gram-negative bacteria ...
In the study described here, we have taken steps to characterize the YjeE protein, an Escherichia coli protein of unknown function that is essential for bacterial viability. YjeE represents a protein family whose members are broadly conserved in bacteria, absent from eukaryotes and contain both Walker A and B motifs, characteristic of P-loop ATPases. We have revisited the dispensability of the yjeE gene in E. coli and describe efforts to probe the function of the YjeE protein with in vitro biochemistry. We have looked critically for ATPase activity in the recombinant E. coli protein and have made vigilant use of site-directed variants in the Walker A [K41A (Lys41→Ala) and T42A] and putative Walker B (D80Q) motifs. We noted that any hydrolysis of ATP by the wild-type E. coli protein might be attributed to background ATPase, since it was not appreciably different from that of the variants. To overcome potential contaminants, we turned to crystalline pure YjeE protein from Haemophilus influenzae ...
What is Escherichia coli?. Escherichia coli (abbreviated as E. coli) are a large and diverse group of bacteria. Although most strains of E. coli are harmless, others can make you sick. Some kinds of E. coli can cause diarrhea, while others cause urinary tract infections, respiratory illness and pneumonia, and other illnesses. Still other kinds of E. coli are used as markers for water contamination-so you might hear about E. coli being found in drinking water, which are not themselves harmful, but indicate the water is contaminated. It does get a bit confusing-even to microbiologists.. What are Shiga toxin-producing E. coli? Some kinds of E. coli cause disease by making a toxin called Shiga toxin. The bacteria that make these toxins are called "Shiga toxin-producing" E. coli, or STEC for short. You might hear them called verocytotoxic E. coli (VTEC) or enterohemorrhagic E. coli (EHEC); these all refer generally to the same group of bacteria. The most commonly identified STEC in North America is ...

This protocol was developed in a project aimed to identify the inner membrane proteins localizing to cell poles in Escherichia coli (E. coli). By using a known polar protein Tar as a tag, we isolated pole-derived inner membrane vesicles by affinity capture. The specificity of the polar vesicle isolation was confirmed by mass spectrometry that identified more than one hundred proteins, most of which are known inner membrane proteins, including other known polar proteins. This protocol, or if adapted properly by choosing other affinity targets, is well suited to isolate other membrane domains of interest for identification of proteins or lipid composition.

The mechanism of transport of KP-736, a novel cephalosporin with a 1,5-dihydroxy-4-pyridone moiety at the C-7 position, into the Escherichia coli K-12 cell was investigated by determining the susceptibilities of iron transport mutants to KP-736. The tonB mutant showed a higher degree of resistance to KP-736, indicating that KP-736 was incorporated into E. coli cells via the tonB-dependent iron transport system. The product of the exbB gene was also necessary for the maximal antibacterial potency of KP-736. Cir-lacking and Fiu-lacking mutants showed a moderate level of resistance to KP-736. However, mutants lacking any one of the proteins FepA, FecA, FhuA, and FhuE did not show any increased resistance to KP-736. Two types of spontaneous mutants (e.g., KT1004 and KT1011) could be isolated from cir and fiu mutants by selection for KP-736 resistance and showed the same level of resistance to KP-736 as a tonB mutant. KT1004 showed tonB phenotypes, resistance to phage phi 80, and loss of FecA, ...
Abstract : Escherichia coli (E. coli) infections are the major health concern, as it causes infections in human mainly in urinarytract, ear, and wound infections. The present study evaluates the impact of biofield energy treatment on E. coli regardingantimicrobial sensitivity assay, biochemical study and biotype number. Four multidrug resistant (MDR) clinical lab isolates (LSs)of E. coli (LS 12, LS 13, LS 42, and LS 51) were taken in two groups i.e. control and treated. After treatment, above mentionedparameter were evaluated on day 10 in control and treated samples using MicroScan Walk-Away® system. The antimicrobialsensitivity assay was reported with 46.67% alteration (14 out of 30 tested antimicrobials) in treated group of MDR E. coli isolates.The minimum inhibitory concentration (MIC) study showed the alteration in MIC values of about 34.37% (11 out of 32) testedantimicrobials, after biofield treatment in clinical isolates of E. coli. Piperacillin/tazobactam was reported with ...
Inhibition of disulfide bond formation in Escherichia coli implicates an intricate collaboration of proteins which comprise the glutathione and thioredoxin reducing pathways. Bioengineers have successfully engineered E. coli possessing mutated reducing pathways that promote, rather than inhibit, disulfide bond formation in the cytoplasm. The transcriptome of six such mutant E. coli strains have been characterized using Microarray technology. We find that all mutant strains, exhibit a unique response to oxidative stress, not observed in wild type. Statistical analyses revealed the expression of more than 200 genes that are affected by mutations within the reducing pathways. Significantly up-regulated biological processes include cysteine biosynthesis, histidine biosynthesis, NADH Dehydrogenase I biosynthesis, sugar catabolic processes, and activation of stress responses . The second part of this work describes the construction of an E. coli strain that promotes the complete conversion of ...

Nucleotide sequences of translated regions of the trp operon in 12 wild strains of Escherichia coli reveal striking uniformity among eight strains (suggesting recent common ancestry and supporting the importance of periodic selection in natural populations) and clustered substitutions in four strains (implicating events affecting runs of nucleotides).
The ability of salt to rescue division in an FtsEX null mutant is enigmatic if FtsEX is needed for proper assembly or stability of the septal ring. Presumably, the downstream essential division proteins, FtsK through FtsN, all of which are required for division even on media containing salt, have some ability to localize in the absence of FtsEX. Consistent with this, RG60 is sensitive to β-lactams that target FtsI (D. Weiss, unpublished data) and we observed localization of FtsN, which is a late recruit to the division site (1), when RG60 was grown under permissive conditions. It is tempting to speculate that the ability of downstream proteins to localize independently of FtsEX is why we observed some residual localization of FtsK, FtsQ, and FtsI in filaments depleted of FtsEX in LB with no salt, but we cannot exclude the less interesting possibility that there is residual FtsEX in these filaments. Our depletion strains express ftsEX from a multicopy plasmid, so we sought to reduce the ...
Slipped-strand mispairing (SSM) has not been identified as a mechanism of phase variation in Escherichia coli. Using a reporter gene, we show that sequences that cause phase variation by SSM in Haemophilus influenzae also lead to phase variation when introduced onto the chromosome of E. coli, and the frequencies of switching are in the biologically relevant range. Thus, the absence of SSM-mediated phase variation in E. coli does not appear to be due to a mechanistic constraint. ...
The bacterium Escherichia coli is making rounds around the world. The bacteria, previously considered far less harmeless has come under in recent months. To be fair, most of the bacteria is commonly found among humans and animals alike. However, its contact with people with antibacterial resistance can lead to severe illnesses. These include cases of blood poisoning or even resulting in septic shocks. The recent breakout of these illnesses due to anti-bacterial resistance lead researchers to look a bit closer. The outbreak of E.Coli happens as some people may eat bad case of raw meat or a poor personal hygiene. If one doesnt wash his hands after visiting a restroom, they are more likely to be at risk from possible infections. This lead scientists to ask which one is more dangerous as a source of infection. Researchers from University of East Anglia in United Kingdom started this discovery on an unclear note. They were puzzled as the healthy bacteria lives in the intestine of most individuals. ...

Mono- and Stereopictres of 5.0 Angstrom coordination sphere of Iron atom in PDB 1fft: The Structure of Ubiquinol Oxidase From Escherichia Coli
The efficient redesign of bacteria for biotechnological purposes, such as biofuel production, waste disposal or specific biocatalytic functions, requires a quantitative systems-level understanding of energy supply, carbon and redox metabolism. The measurement of transcript levels, metabolite concentrations and metabolic fluxes per se gives an incomplete picture. An appreciation of the interdependencies between the different measurement values is essential for systems-level understanding. Mathematical modeling has the potential to provide a coherent and quantitative description of the interplay between gene expression, metabolite concentrations and metabolic fluxes. Escherichia coli undergoes major adaptations in central metabolism when the availability of oxygen changes. Thus, an integrated description of the oxygen response provides a benchmark of our understanding of carbon, energy and redox metabolism. We present the first comprehensive model of the central metabolism of E. coli that describes steady
Bacterial adhesion to other bacteria, to eukaryotic cells, and to extracellular matrix proteins is frequently mediated by cell surface-associated polymers (fimbriae) consisting of one or more subunit proteins. We have found that polymerization of curlin to fimbriae-like structures (curli) on the surface of Escherichia coli markedly differs from the prevailing model for fimbrial assembly in that it occurs extracellularly through a self-assembly process depending on a specific nucleator protein. The cell surface-bound nucleator primes the polymerization of curlin secreted by the nucleator-presenting cell or by adjacent cells. The addition of monomers to the growing filament seems to be driven by mass action and guided only by the diffusion gradient between the source of secreted monomer and the surface of monomer condensation.. ...
Nitric oxide (NO) is a by-product of normal metabolic processes in some bacteria, and part of the arsenal of toxic compounds mammalian cells use to kill invading pathogens. In self-defense, Escherichia coli synthesizes several enzymes that detoxify it. In some cases, these enzymes are made only in cells that have been exposed to NO. Several NO-sensitive regulatory proteins in E. coli have been previously characterized. Now Diane Bodenmiller and Stephen Spiro of Georgia Institute of Technology in Atlanta describe a new NO-responsive regulator, of previously unknown function, which switches off gene expression in the absence of NO.

EINLEITUNG Der Zusammenhang von veränderten intestinalen Mikrobiota und chronisch entzündlichen Darmerkrankungen (CED) wird seit langem diskutiert. Neben einer verringerten bakteriellen Diversität konnte auch die Zunahme einzelner Bakteriengruppen diesen Erkrankungen zugeordnet werden. Die Rolle einer möglicherweise kolitogenen Mikrobiota ist in diesem Zusammenhang jedoch weiter unklar. Kürzlich konnte gezeigt werden, dass α-Hämolysin (HlyA)-produzierende Escherichia coli (E. coli) an einem Enterozytenzellmodell Läsionen, so genannte Focal Leaks, induzieren können. Daher sollte in dieser Arbeit eine intestinale Kolonisation mit HlyA-produzierenden Bakterien in einem in vivo Modell untersucht und ihr möglicher Einfluss auf CED geprüft werden.

One thing that surprises me is how difficult it is to find an Escherichia coli strain that meets a certain set of specifications. For instance, I want a strain with the lactose permease knocked out and the arabinose permease under the control of a constitutive promoter so that I can get linear induction with both lactose and arabinose. I dont think one exists (if it does please email me!). I also cant find a strain that is lacIq and has the lactose permease deleted (again email me if you have this strain!). I find this situation mildly frustrating. I also find the nomenclature of Escherichia coli genotype information to be unnecessarily confusing but I am willing to let it slide as a historical artifact. (See the attempt to decipher the code.) However, in my mind what is truly astonishing is the dearth of information available on existing strains and the fact that some of this information is wrong! Case in point: I was interested in using a strain of Escherichia coli with the lacIq mutation. I ...

In this thesis, we characterize mechanisms responsible for functional and morphological asymmetries in division in E. coli cells, using live, single-cell, single-molecule imaging techniques and detailed stochastic models. First, to understand the functional asymmetries due to the heterogeneous spatial distribution of large, inert protein complexes, we study the kinetics of segregation and retention of such complexes by observing these events, one event at a time. For that, we track individual MS2-GFP tagged RNA complexes, as they move in the cell cytoplasm, and characterize the mechanisms responsible for their long-term spatial distribution and resulting partitioning. Next, to understand the morphological asymmetries, we study the difference in cell sizes between sister cells at division under different environmental conditions. Finally, we present the models and simulators developed to characterize and mimic these processes, as well as to explore their functional consequences ...

Microorganisms of the gastrointestinal (GI) tract were recently shown to communicate and consequently influence the metabolism, immunity, and behavior of animal hosts. Increasing evidence suggest that communication can also occur in the opposite direction, with hormones and other host-secreted compo.... Full description. ...
Antibiotická rezistencia (Antimicrobial Resistance, AMR) je rozšírený jav, pri ktorom antibiotiká prestávajú byť účinné proti pôvodcom infekčných ochoreni, baktérie nadobúdajú voči antibiotikám odolonosť. Rezistencia síce nie je nijak nová skutočnosť, ale jej význam z viacerých dôvodov narastá. Jednak sa neustále zvyšuje jej celkový rozsah a na druhej strane neboli objavené… Read more. ...

Behandlung bei Escherichia coli Die Erkrankung verläuft meist selbstlimitierend, daher reicht der Ausgleich des Elektrolyt- und Wasserhaushalts aus. Die Behandlung mit Antibiotika gilt im Allgemeinen als kontraindiziert, da die Bakterien durch diese Behandlung vermehrt Toxine produzieren.
Our lab is trying to overexpress and isolate a rather large yeast (S. cerevisiae) protein in E.coli. The gene is ca. 4 kb and encodes a protein of 1,433 a.a. We transformed DH5alpha with a plasmid containing the gene, but are unable to see it. Also, when the expression is induced (IPTG), the E.coli become sick (grow slower). Does anyone have any experience expressing large or toxic proteins in E.coli? Any help would be greatly appreciated. -Al (plummer at em.uni-frankfurt.de ...
Escherichia coli is a gram-negative, rod-shaped bacterium. It is a commensal that colonises the gastrointestinal tract within a few hours of birth. E coli becomes pathogenic by acquiring virulence factors or genetic mutations, leading to a broad spectrum of disease. Infection by pathogenic strains occurs through ingestion, usually via contaminated food or water. ...
