The intracellular transfer of information (biological activation/inhibition) through a signal pathway.

Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

The Cryptosporidium "mouse" genotype is conserved across geographic areas. (1/150)

A 298-bp region of the Cryptosporidium parvum 18S rRNA gene and a 390-bp region of the acetyl coenzyme A synthetase gene were sequenced for a range of Cryptosporidium isolates from wild house mice (Mus domesticus), a bat (Myotus adversus), and cattle from different geographical areas. Previous research has identified a distinct genotype, referred to as the "mouse"-derived Cryptosporidium genotype, common to isolates from Australian mice. Comparison of a wider range of Australian mouse isolates with United Kingdom and Spanish isolates from mice and cattle and also an Australian bat-derived Cryptosporidium isolate revealed that the "mouse" genotype is conserved across geographic areas. Mice are also susceptible to infection with the "cattle" Cryptosporidium genotype, which has important implications for their role as reservoirs of infection for humans and domestic animals.  (+info)

The role of an iron-sulfur cluster in an enzymatic methylation reaction. Methylation of CO dehydrogenase/acetyl-CoA synthase by the methylated corrinoid iron-sulfur protein. (2/150)

This paper focuses on how a methyl group is transferred from a methyl-cobalt(III) species on one protein (the corrinoid iron-sulfur protein (CFeSP)) to a nickel iron-sulfur cluster on another protein (carbon monoxide dehydrogenase/acetyl-CoA synthase). This is an essential step in the Wood-Ljungdahl pathway of anaerobic CO and CO2 fixation. The results described here strongly indicate that transfer of methyl group to carbon monoxide dehydrogenase/acetyl-CoA synthase occurs by an SN2 pathway. They also provide convincing evidence that oxidative inactivation of Co(I) competes with methylation. Under the conditions of our anaerobic assay, Co(I) escapes from the catalytic cycle one in every 100 turnover cycles. Reductive activation of the CFeSP is required to regenerate Co(I) and recruit the protein back into the catalytic cycle. Our results strongly indicate that the [4Fe-4S] cluster of the CFeSP is required for reductive activation. They support the hypothesis that the [4Fe-4S] cluster of the CFeSP does not participate directly in the methyl transfer step but provides a conduit for electron flow from physiological reductants to the cobalt center.  (+info)

Purification and catalytic properties of Ech hydrogenase from Methanosarcina barkeri. (3/150)

Methanosarcina barkeri has recently been shown to produce a multisubunit membrane-bound [NiFe] hydrogenase designated Ech (Escherichia coli hydrogenase 3) hydrogenase. In the present study Ech hydrogenase was purified to apparent homogeneity in a high yield. The enzyme preparation obtained only contained the six polypeptides which had previously been shown to be encoded by the ech operon. The purified enzyme was found to contain 0.9 mol of Ni, 11.3 mol of nonheme-iron and 10.8 mol of acid-labile sulfur per mol of enzyme. Using the purified enzyme the kinetic parameters were determined. The enzyme catalyzed the H2 dependent reduction of a M. barkeri 2[4Fe-4S] ferredoxin with a specific activity of 50 U x mg protein-1 at pH 7.0 and exhibited an apparent Km for the ferredoxin of 1 microM. The enzyme also catalyzed hydrogen formation with the reduced ferredoxin as electron donor at a rate of 90 U x mg protein-1 at pH 7.0. The apparent Km for the reduced ferredoxin was 7.5 microM. Reduction or oxidation of the ferredoxin proceeded at similar rates as the reduction or oxidation of oxidized or reduced methylviologen, respectively. The apparent Km for H2 was 5 microM. The kinetic data strongly indicate that the ferredoxin is the physiological electron donor or acceptor of Ech hydrogenase. Ech hydrogenase amounts to about 3% of the total cell protein in acetate-grown, methanol-grown or H2/CO2-grown cells of M. barkeri, as calculated from quantitative Western blot experiments. The function of Ech hydrogenase is ascribed to ferredoxin-linked H2 production coupled to the oxidation of the carbonyl-group of acetyl-CoA to CO2 during growth on acetate, and to ferredoxin-linked H2 uptake coupled to the reduction of CO2 to the redox state of CO during growth on H2/CO2 or methanol.  (+info)

Molecular cloning and cell-cycle-dependent expression of the acetyl-CoA synthetase gene in Tetrahymena cells. (4/150)

To identify transcriptionally regulated mediators associated with the cell cycle, we adopted the differential mRNA display technique for cell cultures of Tetrahymena pyriformis synchronized by cyclic heat treatment. One cDNA fragment that was expressed differently during synchronous cell division had a greatly decreased expression at 30 min after the end of heat treatment (EHT). Using this fragment as a probe, we isolated the full-length cDNA for T. pyriformis acetyl-CoA synthetase (TpAcs) which encodes a 651 amino acid polypeptide with a predicted molecular mass of 72.8 kDa. The deduced amino acid sequence of T. pyriformis ACS shows 42% sequence identity compared with that of Lysobacter sp. acetyl-CoA synthetase (ACS), an enzyme which catalyses the formation of acetyl-CoA from acetate via an acetyl-adenylate intermediate. The deduced sequence is also 41% and 40% identical compared with those of Pseudomonas putida and Coprinus cinereus ACS, respectively. The deduced sequence of T. pyriformis ACS also shares similar characteristics of the conserved motifs I and II in the ACS family. To further investigate the actions of the gene encoding this enzyme, mRNA expression was determined during the course of synchronized cell division in T. pyriformis. Northern blot results show that the mRNA level was dramatically decreased at 30 min after EHT prior to entering synchronous cell division (which occurs 75 min after EHT), suggesting that mRNA expression of the TpAcs was associated with the cell cycle and that the down-regulated expression of TpAcs at 30 min after EHT would be required for the initiation of the oncoming synchronous cell division in T. pyriformis.  (+info)

Oxalic acid production by Aspergillus niger: an oxalate-non-producing mutant produces citric acid at pH 5 and in the presence of manganese. (5/150)

The external pH appeared to be the main factor governing oxalic acid production by Aspergillus niger. A glucose-oxidase-negative mutant produced substantial amounts of oxalic acid as long as the pH of the culture was 3 or higher. When pH was decreased below 2, no oxalic acid was formed. The activity of oxaloacetate acetylhydrolase (OAH), the enzyme believed to be responsible for oxalate formation in A. niger, correlated with oxalate production. OAH was purified from A. niger and characterized. OAH cleaves oxaloacetate to oxalate and acetate, but A. niger never accumulated any acetate in the culture broth. Since an A. niger acuA mutant, which lacks acetyl-CoA synthase, did produce some acetate, wild-type A. niger is apparently able to catabolize acetate sufficiently fast to prevent its production. An A. niger mutant, prtF28, previously isolated in a screen for strains deficient in extracellular protease expression, was shown here to be oxalate non-producing. The prtF28 mutant lacked OAH, implying that OAH is the only enzyme involved in oxalate production in A. niger. In a traditional citric acid fermentation low pH and absence of Mn2+ are prerequisites. Remarkably, a strain lacking both glucose oxidase (goxC) and OAH (prtF) produced citric acid from sugar substrates in a regular synthetic medium at pH 5 and under these conditions production was completely insensitive to Mn2+.  (+info)

sigma(70) is the principal sigma factor responsible for transcription of acs, which encodes acetyl coenzyme A synthetase in Escherichia coli. (6/150)

Cells of Escherichia coli undergo a metabolic switch associated with the production and utilization of acetate. During exponential growth on tryptone broth, these cells excrete acetate via the phosphotransacetylase-acetate kinase (Pta-AckA) pathway. As they begin the transition to stationary phase, they instead resorb acetate, activate it to acetyl coenzyme A (acetyl-CoA) by means of the enzyme acetyl-CoA synthetase (Acs) and utilize it to generate energy and biosynthetic components via the tricarboxylic acid cycle and the glyoxylate shunt, respectively. This metabolic switch depends upon the induction of Acs. As part of our effort to dissect the mechanism(s) underlying induction and to identify the signal(s) that triggers that induction, we sought the sigma factor most responsible for acs expression. Using isogenic strains that carry a temperature sensitivity allele of the gene that encodes sigma(70) and either a wild-type or null allele of the gene that encodes sigma(S), we determined by immunoblotting, reverse transcriptase PCR, and acs::lacZ transcriptional fusion analyses that sigma(70) is the sigma factor primarily responsible for the acs transcription that cells induce during mid-exponential phase. In contrast, sigma(S) partially inhibits that transcription as cells enter stationary phase.  (+info)

Evidence for intersubunit communication during acetyl-CoA cleavage by the multienzyme CO dehydrogenase/acetyl-CoA synthase complex from Methanosarcina thermophila. Evidence that the beta subunit catalyzes C-C and C-S bond cleavage. (7/150)

The carbon monoxide dehydrogenase/acetyl-CoA synthase (CODH/ACS) from Methanosarcina thermophila is part of a five-subunit complex consisting of alpha, beta, gamma, delta, and epsilon subunits. The multienzyme complex catalyzes the reversible oxidation of CO to CO(2), transfer of the methyl group of acetyl-CoA to tetrahydromethanopterin (H(4)MPT), and acetyl-CoA synthesis from CO, CoA, and methyl-H(4)MPT. The alpha and epsilon subunits are required for CO oxidation. The gamma and delta subunits constitute a corrinoid iron-sulfur protein that is involved in the transmethylation reaction. This work focuses on the beta subunit. The isolated beta subunit contains significant amounts of nickel. When proteases truncate the beta subunit, causing the CODH/ACS complex to dissociate, the amount of intact beta subunit correlates directly with the EPR signal intensity of Cluster A and the activity of the CO/acetyl-CoA exchange reaction. Our results strongly indicate that the beta subunit harbors Cluster A, a NiFeS cluster, that is the active site of acetyl-CoA cleavage and assembly. Although the beta subunit is necessary, it is not sufficient for acetyl-CoA synthesis; interactions between the CODH and the ACS subunits are required for cleavage or synthesis of the C-C bond of acetyl-CoA. We propose that these interactions include intramolecular electron transfer reactions between the CODH and ACS subunits.  (+info)

Acetyl-CoA synthetase from the amitochondriate eukaryote Giardia lamblia belongs to the newly recognized superfamily of acyl-CoA synthetases (Nucleoside diphosphate-forming). (8/150)

The gene coding for the acetyl-CoA synthetase (ADP-forming) from the amitochondriate eukaryote Giardia lamblia has been expressed in Escherichia coli. The recombinant enzyme exhibited the same substrate specificity as the native enzyme, utilizing acetyl-CoA and adenine nucleotides as preferred substrates and less efficiently, propionyl- and succinyl-CoA. N- and C-terminal parts of the G. lamblia acetyl-CoA synthetase sequence were found to be homologous to the alpha- and beta-subunits, respectively, of succinyl-CoA synthetase. Sequence analysis of homologous enzymes from various bacteria, archaea, and the eukaryote, Plasmodium falciparum, identified conserved features in their organization, which allowed us to delineate a new superfamily of acyl-CoA synthetases (nucleoside diphosphate-forming) and its signature motifs. The representatives of this new superfamily of thiokinases vary in their domain arrangement, some consisting of separate alpha- and beta-subunits and others comprising fusion proteins in alpha-beta or beta-alpha orientation. The presence of homologs of acetyl-CoA synthetase (ADP-forming) in such human pathogens as G. lamblia, Yersinia pestis, Bordetella pertussis, Pseudomonas aeruginosa, Vibrio cholerae, Salmonella typhi, Porphyromonas gingivalis, and the malaria agent P. falciparum suggests that they might be used as potential drug targets.  (+info)

The core of the Augusta physicians legal challenge was that the RUC is a de facto Federal Advisory Committee, and therefore subject to the stringent accountability requirements of the Federal Advisory Committee Act (FACA). This law ensures that federal bodies have panel compositions that are numerically representative of their constituencies, that their proceedings are open, and that methodologies are scientifically credible. In other words, FACA ensures that advisory practices are aligned with the public interest.. The RUC adheres to none of these and is an object lesson in how special interests can be insinuated into and capture regulatory processes, displacing the public interest. For example, when the legal challenge was first filed, only 3 of 29 RUC panelists (10 percent) represented primary care, even though some 30 percent of US physicians practice primary care. RUC meetings are closed to the public, unless an invitation is extended by the Chair, and admission is tied to the guest ...

Author(s): Zhuang, Wei-Qin; Yi, Shan; Bill, Markus; Brisson, Vanessa L; Feng, Xueyang; Men, Yujie; Conrad, Mark E; Tang, Yinjie J; Alvarez-Cohen, Lisa | Abstract: The acetyl-CoA Wood-Ljungdahl pathway couples the folate-mediated one-carbon (C1) metabolism to either CO2 reduction or acetate oxidation via acetyl-CoA. This pathway is distributed in diverse anaerobes and is used for both energy conservation and assimilation of C1 compounds. Genome annotations for all sequenced strains of Dehalococcoides mccartyi, an important bacterium involved in the bioremediation of chlorinated solvents, reveal homologous genes encoding an incomplete Wood-Ljungdahl pathway. Because this pathway lacks key enzymes for both C1 metabolism and CO2 reduction, its cellular functions remain elusive. Here we used D. mccartyi strain 195 as a model organism to investigate the metabolic function of this pathway and its impacts on the growth of strain 195. Surprisingly, this pathway cleaves acetyl-CoA to donate a methyl group for
Without this transfer of single carbon units involving B12, and its partner B9 (otherwise known as folic acid), heart disease and birth defects might be far more common, explains Ragsdale, a professor of biological chemistry. Similarly, the bacteria that rely on this reaction would be unable to consume carbon dioxide or carbon monoxide to stay alive - and to remove gas from our guts or our atmosphere. So its important on many levels.. In such bacteria, called anaerobes, the reaction is part of a larger process called the Wood-Ljungdahl pathway. Its what enables the organisms to live off of carbon monoxide, a gas that is toxic to other living things, and carbon dioxide, which is a greenhouse gas directly linked to climate change. Ragsdale notes that industry is currently looking at harnessing the Wood-Ljungdahl pathway to help generate liquid fuels and chemicals.. In addition to his Medical School post, Ragsdale is a member of the faculty of the U-M Energy Institute.. In the images created ...
BACKGROUNDMethyltetrahydrofolate, corrinoid iron-sulfur protein methyltransferase (MeTr), catalyzes a key step in the Wood-Ljungdahl pathway of carbon dioxide fixation. It transfers the N5-methyl group from methyltetrahydrofolate (CH3-H4folate) to a cob(I)amide center in another protein, the corrinoid iron-sulfur protein. MeTr is a member of a family of proteins that includes methionine synthase and methanogenic enzymes that activate the methyl group of methyltetra-hydromethano(or -sarcino)pterin. We report the first structure of a protein in this family.RESULTSWe determined the crystal structure of MeTr from Clostridium thermoaceticum at 2.2 A resolution using multiwavelength anomalous diffraction methods. The overall architecture presents a new functional class of the versatile triose phosphate isomerase (TIM) barrel fold. The MeTr tertiary structure is surprisingly similar to the crystal structures of dihydropteroate synthetases despite sharing less than 20% sequence identity. This homology ...

Munca in sine e un lucru normal si chiar amuzant atata timp cat se face rational si cumpatat. Omul poate supravietui cu usurinta depunand o munca simpla si discreta iar jobul este astfel amuzament pur si simplu si placere. Din pacate lacomia congenitala istorica a privilegiatilor social a facut ca o buna parte a societatii sa devina workoholica. Munca a devenit unul dintre cele mai nesuferite lucruri pe care omul clasic si contemporan trebuie sa le faca. Falsele valori educationale si morale sadite sistematic de publicitate sau/si cultura clasica in sufletul omului simplu sunt puse acolo de sistemul social clasic si contemporan tocmai pentru a-l convinge sa munceasca in plus si sa serveasca aceasta lacomie fara margini a acestor cyborgi. Mutilarea spiritului uman este pretul pentru satisfacerea unei lacomii halucinante a privilegiatilor social. Consumul insuficient al sclavului clasic a fost inlocuit de supraconsumul societatii contemporane. In disperarea sa genealogica semisclavul contemporan ...

Syntrophus aciditrophicusis a model syntrophic bacterium that degrades key intermediates in anaerobic decomposition, such as benzoate, cyclohexane-1-carboxylate, and certain fatty acids, to acetate when grown with hydrogen-/formate-consuming microorganisms. ATP formation coupled to acetate production is the main source for energy conservation byS. aciditrophicus. However, the absence of homologs for phosphate acetyltransferase and acetate kinase in the genome ofS. aciditrophicusleaves it unclear as to how ATP is formed, as most fermentative bacteria rely on these two enzymes to synthesize ATP from acetyl coenzyme A (CoA) and phosphate. Here, we combine transcriptomic, proteomic, metabolite, and enzymatic approaches to show thatS. aciditrophicususes AMP-forming, acetyl-CoA synthetase (Acs1) for ATP synthesis from acetyl-CoA.acs1mRNA and Acs1 were abundant in transcriptomes and proteomes, respectively, ofS. aciditrophicusgrown in pure culture and coculture.

Fig. 3 Reconstruction of the complete degradation of n-alkanes and monoaromatic compounds to CO2. The normalized absolute abundances of the genes for each step are given in the respective cells. The selection of the genes for the anaerobic degradation of aromatic compounds was based on the proteogenomics-based reconstruction of their catabolism in the denitrifying Aromatoleum aromaticum EbN1 [78] and the sulfate-reducing Desulfobacula toluolica Tol2 [15]. Only genes with abundances higher than 30 reads in at least one sample are presented. The boxplots depict the log fold changes of the abundances of all genes coding for the enzymes of the anaerobic degradation of phenolic compounds and the Wood-Ljungdahl pathway, respectively. Each sample was compared to the sample at 40-60-cm depth of the same site.

Due to its tendency to recur and acquire chemoresistance quickly, bladder cancer (BC) remains to be an elusive and difficult disease. Patients with recurrent and chemoresistant BC have an extremely poor prognosis. One possible approach that may provide insightful and valuable information regarding resistance mechanisms is looking into the lipid metabolism of BC cells. Metabolism of lipids is essential for cancer cells and is associated with the regulation of a variety of key cellular processes and functions. This study conducted a comparative lipidomic profiling of two isogenic human T24 bladder cancer cell lines, one of which is clinically characterized as cisplatin-sensitive (T24S) and the other as cisplatin-resistant (T24R). Immunohistochemistry analysis revealed that expression of cytosolic acetyl-CoA synthetase 2 (ACSS2) is positively correlated with aggressive BC. Ultra performance liquid chromatography-mass spectrometry (UPLC-MS) analysis profiled a total of 1,864 lipids and levels of
Dysphagia is a common complication following ACSS. While several instruments are available for assessing dysphagia, none are particularly well designed for the ACSS population.3,16 A standardized tool that allows quantifiable assessment of dysphagia is needed to allow evaluation of dysphagia rates between studies. Although validated, the SWAL-QOL is lengthy and cumbersome to complete, particularly for patients undergoing ACSS with relatively minor swallowing impairment. As such, the purpose of this paper was to develop a concise, yet clinically relevant survey for use in patients undergoing ACSS.. The results of this study suggest that the SWAL-QOL survey in its full form is not necessary to detect swallowing changes in the ACSS population. Several sections and individual questions demonstrated little to no change from preoperative to postoperative values, indicating the severity of dysphagia following ACSS is not as extreme as the dysphagia in the population for which the SWAL-QOL was ...

Evie Hamilton are un secret. Unul de care inca nici nu e constienta. Evie este nevasta unui barbat chipes, cu o cariera de succes, si mama unei adolescente cu rezultate exceptionale la invatatura, iar cea mai mare grija a ei pe lumea asta este daca are sau nu timp sa-si programeze o manichiura in timp ce se duce sa-si ia fiica de la lectiile de clarinet. Evie nu se gandeste prea mult la alte lucruri in afara celor legate de rutina zilnica a familiei, si asta pentru ca pur si simplu nu are timp. Insa toata aceasta stare confortabila de liniste - sau monotonie - e pe cale sa se schimbe. Intr-o dimineata insorita, Evie se trezeste cu o scrisoare de la Oxford, care pare sa aiba efectul unei bombe cu ceas.
