Utilization of exogenous purine compounds in Bacillus cereus. Translocation of the ribose moiety of inosine. (1/679)

Intact cells of Bacillus cereus catalyze the breakdown of exogenous AMP to hypoxanthine and ribose 1-phosphate through the successive action of 5'-nucleotidase, adenosine deaminase, and inosine phosphorylase. Inosine hydrolase was not detectable, even in crude extracts. Inosine phosphorylase causes a "translocation" of the ribose moiety (as ribose 1-phosphate) inside the cell, while hypoxanthine remains external. Even though the equilibrium of the phosphorolytic reaction favors nucleoside synthesis, exogenous inosine (as well as adenosine and AMP) is almost quantitatively transformed into external hypoxanthine, since ribose 1-phosphate is readily metabolized inside the cell. Most likely, the translocated ribose 1-phosphate enters the sugar phosphate shunt, via its prior conversion into ribose 5-phosphate, thus supplying the energy required for the subsequent uptake of hypoxanthine in B. cereus.  (+info)

A new synthesis of 5'-deoxy-8,5'-cyclo-adenosine and -inosine: conformationally-fixed purine nucleosides (nucleosides and nucleotides. XVI). (2/679)

A versatile method for the synthesis of 5'-deoxy-8,5'-cycloadenosine, a conformationally-fixed "anti" type of adenosine, was presented. Irradiation of 2', 3'-O-isopropylidene-5'-deoxy-5'-phenylthioadenosine with 60W Hg vapor lamp afforded 2',3'-O-isopropylidene-5'-deoxy-8,5'-cycloadenosine in high yield. The use of other 5'-alkylthio derivatives also gave the cycloadenosine, though the yields were rather poor. Deacetonation of the cyclocompound with 0.1N HCl gave 5'-deoxy-8,5'-cycloadenosine. The cycloinosine derivative was similarly prepared. The nmr, mass and CD spectra of 5'-deoxy-8,5'-cycloadenosine were given and discussed with the previously reported results.  (+info)

DNA contacts stimulate catalysis by a poxvirus topoisomerase. (4/679)

Eukaryotic type 1B topoisomerases act by forming covalent enzyme-DNA intermediates that transiently nick DNA and thereby release DNA supercoils. Here we present a study of the topoisomerase encoded by the pathogenic poxvirus molluscum contagiosum. Our studies of DNA sites favored for catalysis reveal a larger recognition site than the 5'-(T/C)CCTT-3' sequence previously identified for poxvirus topoisomerases. Separate assays of initial DNA binding and covalent complex formation revealed that different DNA sequences were important for each reaction step. The location of the protein-DNA contacts was mapped by analyzing mutant sites and inosine-substituted DNAs. Some of the bases flanking the 5'-(T/C)CCTT-3' sequence were selectively important for covalent complex formation but not initial DNA binding. Interactions important for catalysis were probed with 5'-bridging phosphorothiolates at the site of strand cleavage, which permitted covalent complex formation but prevented subsequent religation. Kinetic studies revealed that the flanking sequences that promoted recovery of covalent complexes increased initial cleavage instead of inhibiting resealing of the nicked intermediate. These data 1) indicate that previously unidentified DNA contacts can accelerate a step between initial binding and covalent complex formation and 2) help specify models for conformational changes promoting catalysis.  (+info)

RNA editing of the human serotonin 5-hydroxytryptamine 2C receptor silences constitutive activity. (5/679)

RNA transcripts encoding the serotonin 5-hydroxytryptamine 2C (5-HT2C) receptor (5-HT2CR) undergo adenosine-to-inosine RNA editing events at up to five specific sites. Compared with rat brain, human brain samples expressed higher levels of RNA transcripts encoding the amino acids valine-serine-valine (5-HT2C-VSV) and valine-glycine-valine (5-HT2C-VGV) at positions 156, 158, and 160, respectively. Agonist stimulation of the nonedited human receptor (5-HT2C-INI) and the edited 5-HT2C-VSV and 5-HT2C-VGV receptor variants stably expressed in NIH-3T3 fibroblasts demonstrated that serotonergic agonists were less potent at the edited receptors. Competition binding experiments revealed a guanine nucleotide-sensitive serotonin high affinity state only for the 5-HT2C-INI receptor; the loss of high affinity agonist binding to the edited receptor demonstrates that RNA editing generates unique 5-HT2CRs that couple less efficiently to G proteins. This reduced G protein coupling for the edited isoforms is primarily due to silencing of the constitutive activity of the nonedited 5-HT2CR. The distinctions in agonist potency and constitutive activity suggest that different edited 5-HT2CRs exhibit distinct responses to serotonergic ligands and further imply that RNA editing represents a novel mechanism for controlling physiological signaling at serotonergic synapses.  (+info)

Metabolism and the triggering of germination of Bacillus megaterium. Concentrations of amino acids, organic acids, adenine nucleotides and nicotinamide nucleotides during germination. (6/679)

A considerable amount of evidence suggests that metabolism of germinants or metabolism stimulated by them is involved in triggering bacterial-spore germination. On the assumption that such a metabolic trigger might lead to relatively small biochemical changes in the first few minutes of germination, sensitive analytical techniques were used to detect any changes in spore components during the L-alanine-triggered germination of Bacillus megaterium KM spores. These experiments showed that no changes in spore free amino acids or ATP occurred until 2-3 min after L-alanine addition. Spores contained almost no oxo acids (pyruvate, alpha-oxoglutarate, oxaloacetate), malate or reduced NAD. These compounds were again not detectable until 2-3 min after addition of germinants. It is suggested, therefore, that metabolism associated with these intermediates is not involved in the triggering of germination of this organism.  (+info)

Long RNA hairpins that contain inosine are present in Caenorhabditis elegans poly(A)+ RNA. (7/679)

Adenosine deaminases that act on RNA (ADARs) are RNA-editing enzymes that convert adenosine to inosine within double-stranded RNA. In the 12 years since the discovery of ADARs only a few natural substrates have been identified. These substrates were found by chance, when genomically encoded adenosines were identified as guanosines in cDNAs. To advance our understanding of the biological roles of ADARs, we developed a method for systematically identifying ADAR substrates. In our first application of the method, we identified five additional substrates in Caenorhabditis elegans. Four of those substrates are mRNAs edited in untranslated regions, and one is a noncoding RNA edited throughout its length. The edited regions are predicted to form long hairpin structures, and one of the RNAs encodes POP-1, a protein involved in cell fate decisions.  (+info)

Editing of messenger RNA precursors and of tRNAs by adenosine to inosine conversion. (8/679)

The double-stranded RNA-specific adenosine deaminases ADAR1 and ADAR2 convert adenosine (A) residues to inosine (I) in messenger RNA precursors (pre-mRNA). Their main physiological substrates are pre-mRNAs encoding subunits of ionotropic glutamate receptors or serotonin receptors in the brain. ADAR1 and ADAR2 have similar sequence features, including double-stranded RNA binding domains (dsRBDs) and a deaminase domain. The tRNA-specific adenosine deaminases Tad1p and Tad2p/Tad3p modify A 37 in tRNA-Ala1 of eukaryotes and the first nucleotide of the anticodon (A 34) of several bacterial and eukaryotic tRNAs, respectively. Tad1p is related to ADAR1 and ADAR2 throughout its sequence but lacks dsRBDs. Tad1p could be the ancestor of ADAR1 and ADAR2. The deaminase domains of ADAR1, ADAR2 and Tad1p are very similar and resemble the active site domains of cytosine/cytidine deaminases.  (+info)

Combinations of thymidine and inosine (ranging from 0 to 7.5 mg/hr) were co-administered during a 72-hr continuous i.v. infusion of 3 μg/hr methotrexate in normal and P388 solid tumor-bearing DBA/2 mice. Methotrexate alone was lethal to all normal mice. Inosine at 1.0-7.5 mg/hr could reverse toxicity up to 100% while ... read more thymidine at 0.5-7.5 mg/hr was less effective (86% survival). Combinations of the nucleosides averted toxicity more effectively than either compound alone and in a synergistic manner. From P388 tumor-bearing mice 27% survived methotrexate and eventually died of tumor. Co-infusion of thymidine or inosine decreased the percentage of toxic deaths and caused an increase in life span of more than 50% as compared to untreated tumor-bearing mice. However, the diminishing effect on survival with thymidine and inosine doses above 0.5 mg/hr indicated loss of the antitumor effect of methotrexate. This was also observed with combinations of the nucleosides. The influence of ...

Historically, the first universal base employed was 2-deoxyInosine (dI). DeoxyInosine is a naturally occurring base that, while not truly universal, is less destabilizing than mismatches involving the four standard bases. Hydrogen bond interactions between dI and dA, dG, dC and dT are weak and unequal, with the result that some base-pairing bias does exist with dI:dC , dI:dA , dI:dG , dI:dT. When present in a DNA template, deoxyInosine preferentially directs incorporation of dC in the growing nascent strand by DNA polymerase.. ...

Although many editing sites have recently been discovered2,3,4,5,6,7, the extent to which most sites are edited and how the editing is regulated in different biological contexts are not fully understood8,9,10. Here we report dynamic spatiotemporal patterns and new regulators of RNA editing, discovered through an extensive profiling of A-to-I RNA editing in 8,551 human samples (representing 53 body sites from 552 individuals) from the Genotype-Tissue Expression (GTEx) project and in hundreds of other primate and mouse samples. We show that editing levels in non-repetitive coding regions vary more between tissues than editing levels in repetitive regions. Globally, ADAR1 is the primary editor of repetitive sites and ADAR2 is the primary editor of non-repetitive coding sites, whereas the ...
Double-stranded RNA triggers various profound cellular reactions, which depend not only on different intracellular dsRNA locations, but also on the intrinsic structure and length of the duplex. One of the major cellular responses to nuclear dsRNA is the covalent base modification of the target dsRNA by a ubiquitously expressed enzyme, ADAR. ADAR works on dsRNA and alters adenosines to inosines in the RNA duplex. Two types of ADAR editing of dsRNA have been found, selective editing and the promiscuous hyperediting. Hyperedited RNA has been suggested to undergo a novel regulatory pathway. How do cells discriminate between selectively edited mRNAs that encode new protein isoforms, and dsRNA-induced, promiscuously edited RNAs that encode nonfunctional, mutant proteins? We have developed a Xenopus oocyte model system which shows that a variety of hyperedited, inosine-containing RNAs are specifically retained in the nucleus. To uncover the mechanism of inosine-induced retention, HeLa cell nuclear extracts

A water bridge is observed in the minor groove side of the base tetrad. Even though it is sandwiched by guanine tetrads (G tetrads), the I tetrad is buckled towards the 3′ side of the tetrad plane, which results from the different interaction strength with K ions on two sides of the tetrad plane. Comparison with both G tetrad and adenine tetrad indicates that lack of NH2 in the C2 position makes the I ...

RNA editing is a regulatory mechanism in which nucleotides are altered posttranscriptionally and most frequently involves conversion of adenosine to inosine, which is recognized as a guanosine during translation. Chen and colleagues performed RNA sequencing analysis to identify molecular changes in hepatocellular carcinoma (HCC) samples that might contribute to disease progression, and they detected elevated adenosine-to-inosine RNA editing of antizyme inhibitor 1 (AZIN1) in HCC samples compared with adjacent normal tissues. The frequency of AZIN1 editing increased during HCC progression and was correlated with liver cirrhosis, tumor recurrence, and poor prognosis, suggesting that this recoding event may promote HCC pathogenesis. AZIN1 RNA modification was mediated by the p110 isoform of adenosine deaminase, RNA-specific (ADAR1), but not by other ADAR family members, and resulted in substitution of glycine for serine at residue 367 in the AZIN1 protein, which was predicted to induce a ...

N2 - Liver ischemia represents a common clinical problem. In the present study, using an in vitro model of hepatic ischemia-reperfusion injury, we evaluated the potential cyto-protective effect of the purine metabolites, such as adenosine and inosine, and studied the mode of their pharmacological actions. The human hepatocellular carcinoma-derived cell line HepG2 was subjected to combined oxygen-glucose deprivation (COGD; 0-14-24 h), followed by re-oxygenation (0-4-24 h). Adenosine or inosine (300-1,000 μM) were applied in pretreatment. Cell viability and cytotoxicity were measured by the 3-(4,5-dimethyl-2-thiazolyl)-2, ...
Adenosine deaminase (ADA) is a purine catabolic enzyme ubiquitous in mammalian tissue which catalyzes deamination of both adenosine and 2-deoxyadenosine to inosine and 2-deoxyinosine respectively. ...
The pyrimidine-specific nucleoside hydrolase Yeik (CU-NH) from Escherichia coli cleaves the N-glycosidic bond of uridine and cytidine with a 102~104-fold faster than that of purine nucleoside substrates such as inosine. Such remarkable substrate specificity and the plausible hydrolytic mechanisms of uridine have been explored by using QM/MM and MM MD simulations. The present calculations show that the relatively stronger hydrogen bond interactions between uridine and the active-site residues Gln227 and Tyr231 in CU-NH play an important role in enhancing the substrate binding and thus promoting the N-glycosidic bond cleavage, in comparison with inosine ...
Isoprinosine is a nucleoside an alkylamino-alcohol complex of inosine used in the treatment of a variety of viral infections CAS: 36703-88-5. 4-acetamidobenzoic acid compound with 9-((2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-1,9-dihydro-6H-purin-6-one and 1-(dimethylamino)propan-2-ol (3:1:3).
Running the UV-vis scan for each reagent showed that the increasing trend observed on the ADA kinetic assays was inosine not adenosine. This was verified by recalculating the molar absorptivities. The molar absortivity of inosine at 235 is greater than adenosine. This explains the increase over time since as ADA catalyzes the formation of inosine from adenosine; the catalysis increases the concentration of inosine so as its absorbance ...

Benzo[a]pyrene, a potent human carcinogen, is metabolized in vivo to a diol epoxide that reacts with the N -position of guanine to produce N -BP-dG adducts. These adducts are mutagenic causing G to T transversions. These adducts block replicative polymerases but can be bypassed by the Y-family translesion synthesis polymerases. The mechanisms by which mutagenic bypass occurs is not well-known. We have evaluated base pairing structures using atomic substitution of the dNTP with two stereoisomers, 2-deoxy-N-[(7R,8S,9R,10S)-7,8,9,10-tetrahydro-7,8,9-trihydroxybenzo[a]pyren-10-yl]guanosine and 2-deoxy-N-[(7S,8R,9S,10R)-7,8,9,10-tetrahydro-7,8,9-trihydroxybenzo[a]pyren-10-yl]guanosine. We have examined the kinetics of incorporation of 1-deaza-dATP, 7-deaza-dATP, 2-deoxyinosine triphosphate, and 7-deaza-dGTP, analogues of dATP and dGTP in which single atoms are changed. Changes in rate will occur if that atom provided a critical interaction in the transition state of the reaction. We examined two ...

Adenosine-to-inosine (A-to-I) deamination is a functionally important modification of RNA that occurs in many metazoan nuclear transcripts, in several types tRNAs, and in mitochondrial...
RNA editing is the post-transcriptional modification of RNA nucleotides from their genome encoded sequence. The most common type of editing in metazoans is deamination of Adenosine into Inosine catalyzed by the ADAR family of proteins. Subsequently, Inosine is interpreted as Guanosine by the cellular machinery.. The development of high-throughput sequencing technologies has enabled the transcriptome-wide identification of A-to-I editing sites. This database aims to present a comprehensive collection of A-to-I editing sites in human, mouse, and fly transcripts. Useful annotations were incorporated as described in the tutorial.. News:. December 24, 2014: RADAR has been updated to version 2! We have added 8 additional papers to the database. We also removed ~3,000 human genomic SNPs from the database..

Clinical Trial Considers Inosine Safe and May Lead to Future Treatments to Slow the Progression of PARKINSONS DISEASE. Michael Schwarzschild, M.D., Ph.D. who is connected to the Harvard School of Public Health and Massachusetts General Hospital has been conducting research with urate levels for many years. In a report issued in May 2012, he stated that they had rather unexpectedly found that people who had higher levels of urate (uric acid) also had a lower than average chance of developing PARKINSONS DISEASE. In that study, they found that urate served as an antioxidant that could protect cells from cell death, however it required the assistance or cooperation of neighboring cells, called astrocytes. Astrocytes are cells that provide both structural and metabolic support to neurons and it is their intervention that determines how the urate is used within the neural cells. The next question was to find out if urate increased artificially would provide the same protection as urate produced ...
