Capillary electrophoresis for detection of inherited disorders of purine and pyrimidine metabolism. (1/51)

BACKGROUND: Measurement of purine and pyrimidine metabolites presents complex problems for separations currently performed by HPLC and thin-layer chromatography in clinical practice. We developed a novel capillary electrophoresis method for this purpose. METHODS: Separations were performed in 60 mmol/L borate-2-amino-2-methyl-1-propanol-80 mmol/L sodium dodecyl sulfate (pH 9.6) at 35 degrees C. RESULTS: The conditions reported allowed separation of all diagnostic metabolites from major urinary constituents in an analysis time of 3 min and with a separation efficiency of 220 000 theoretical plates/m. The clinically important metabolites were detectable at concentrations of 0.85-4.28 micromol/L. The method was linear over the range 5-500 micromol/L (r >0.99). The within-run and intra- and interday imprecision (CV) was <5%. Characteristic abnormalities were detected in the electropherograms of urine samples from patients with purine and pyrimidine enzyme deficiencies. We provide the electrophoretic and spectral characteristics of many intermediates in purine and pyrimidine metabolism and describe common artifacts from medication and ultraviolet-absorbing compounds. CONCLUSION: Capillary electrophoresis is a valuable screening tool in the detection of inborn errors of purine and pyrimidine metabolism.  (+info)

The structure of adenylosuccinate lyase, an enzyme with dual activity in the de novo purine biosynthetic pathway. (2/51)

BACKGROUND: Adenylosuccinate lyase is an enzyme that plays a critical role in both cellular replication and metabolism via its action in the de novo purine biosynthetic pathway. Adenylosuccinate lyase is the only enzyme in this pathway to catalyze two separate reactions, enabling it to participate in the addition of a nitrogen at two different positions in adenosine monophosphate. Both reactions catalyzed by adenylosuccinate lyase involve the beta-elimination of fumarate. Enzymes that catalyze this type of reaction belong to a superfamily, the members of which are homotetramers. Because adenylosuccinate lyase plays an integral part in maintaining proper cellular metabolism, mutations in the human enzyme can have severe clinical consequences, including mental retardation with autistic features. RESULTS: The 1.8 A crystal structure of adenylosuccinate lyase from Thermotoga maritima has been determined by multiwavelength anomalous dispersion using the selenomethionine-substituted enzyme. The fold of the monomer is reminiscent of other members of the beta-elimination superfamily. However, its active tetrameric form exhibits striking differences in active-site architecture and cleft size. CONCLUSIONS: This first structure of an adenylosuccinate lyase reveals that, along with the catalytic base (His141) and the catalytic acid (His68), Gln212 and Asn270 might play a vital role in catalysis by properly orienting the succinyl moiety of the substrates. We propose a model for the dual activity of adenylosuccinate lyase: a single 180 degrees bond rotation must occur in the substrate between the first and second enzymatic reactions. Modeling of the pathogenic human S413P mutation indicates that the mutation destabilizes the enzyme by disrupting the C-terminal extension.  (+info)

Succinylpurinemic autism: increased sensitivity of defective adenylosuccinate lyase towards 4-hydroxy-2-nonenal. (3/51)

We studied the effect of trans-4-hydroxy-2-nonenal on the wild-type human adenylosuccinate lyase and on the enzyme from a patient compound-heterozygous for two missense mutations (P75A/D397Y; McKusick 103050.0003/103050.0004). Both the enzymes were inhibited by 10-50 microM trans-4-hydroxy-2-nonenal in a concentration-dependent manner by means of a mixed-type co-operative mechanism. A significantly stronger inhibition was noticed in the presence of the defective enzyme. Nonanal and trans-2,3-nonenal inhibited the enzymes to a less extent and at about 10-times higher concentrations. Hydroxylamine reversed the inhibition by trans-4-hydroxy-2-nonenal, trans-2,3-nonenal or nonanal in the case of the wild-type enzyme, but it was ineffective to reverse the inhibition by trans-4-hydroxy-2-nonenal on the defective enzyme. Dithiothreitol slightly decreased the inhibition exerted by trans-4-hydroxy-2-nonenal on both the wild-type and the defective adenylosuccinate lyase, while it did not produce practically any change in the presence of trans-2,3-nonenal or nonanal.  (+info)

Human adenylosuccinate lyase (ADSL), cloning and characterization of full-length cDNA and its isoform, gene structure and molecular basis for ADSL deficiency in six patients. (4/51)

Adenylosuccinate lyase (ADSL) is a bifunctional enzyme acting in de novo purine synthesis and purine nucleotide recycling. ADSL deficiency is a selectively neuronopathic disorder with psychomotor retardation and epilepsy as leading traits. Both dephosphorylated enzyme substrates, succinylaminoimidazole-carboxamide riboside (SAICAr) and succinyladenosine (S-Ado), accumulate in the cerebrospinal fluid (CSF) of affected individuals with S-Ado/SAICAr concentration ratios proportional to the phenotype severity. We studied the disorder at various levels in a group of six patients with ADSL deficiency. We identified the complete ADSL cDNA and its alternatively spliced isoform resulting from exon 12 skipping. Both mRNA isoforms were expressed in all the tissues studied with the non-spliced form 10-fold more abundant. Both cDNAs were expressed in Escherichia coli and functionally characterized at the protein level. The results showed only the unspliced ADSL to be active. The gene consists of 13 exons spanning 23 kb. The promotor region shows typical features of the housekeeping gene. Eight mutations were identified in a group of six patients. The expression studies of the mutant proteins carried out in an attempt to study genotype-phenotype correlation showed that the level of residual enzyme activity correlates with the severity of the clinical phenotype. All the mutant enzymes studied in vitro displayed a proportional decrease in activity against both of their substrates. However, this was not concordant with strikingly different concentration ratios in the CSF of individual patients. This suggests either different in vivo enzyme activities against each of the substrates and/or their different turnover across the CSF-blood barrier, which may be decisive in determining disease severity.  (+info)

Clinical, biochemical and molecular genetic correlations in adenylosuccinate lyase deficiency. (5/51)

Adenylosuccinate lyase (ADSL) deficiency (MIM 103050) is an autosomal recessive inborn error of purine synthesis characterized by the accumulation in body fluids of succinylaminoimidazolecarboxamide (SAICA) riboside and succinyladenosine (S-Ado), the dephosphorylated derivatives of the two substrates of the enzyme. Because ADSL-deficient patients display widely variable degrees of psychomotor retardation, we have expressed eight mutated ADSL enzymes as thioredoxin fusions and compared their properties with the clinical and biochemical characteristics of 10 patients. Three expressed mutated ADSL enzymes (M26L, R426H and T450S) were thermolabile, four (A2V, R141W, R303C and S395R) were thermostable and one (del206-218), was inactive. Thermolabile mutations decreased activities with SAICA ribotide (SAICAR) and adenylosuccinate (S-AMP) in parallel, or more with SAICAR than with S-AMP. Patients homozygous for one of these mutations, R426H, displayed similarly decreased ADSL activities in their fibroblasts, S-Ado:SAICA riboside ratios of approximately 1 in their cerebrospinal fluid and were profoundly retarded. With the exception of A2V, thermostable mutations decreased activity with S-AMP to a much more marked extent than with SAICAR. Two unrelated patients homozygous for one of the thermostable mutations, R303C, also displayed a much more marked decrease in the activity of fibroblast ADSL with S-AMP than with SAICAR, had S-Ado:SAICA riboside ratios between 3 and 4 in their cerebrospinal fluid and were mildly retarded. These results suggest that, in some cases, the genetic lesion of ADSL determines the ratio of its activities with S-AMP versus SAICAR, which in turn defines the S-Ado:SAICA riboside ratio and the patients' mental status.  (+info)

Mutation of a nuclear respiratory factor 2 binding site in the 5' untranslated region of the ADSL gene in three patients with adenylosuccinate lyase deficiency. (6/51)

Adenylosuccinate lyase (ADSL; also called "adenylosuccinase") catalyzes two steps in the synthesis of purine nucleotides: (1) the conversion of succinylaminoimidazolecarboxamide ribotide into aminoimidazolecarboxamide ribotide and (2) the conversion of adenylosuccinate into adenosine monophosphate. ADSL deficiency, a recessively inherited disorder, causes variable-but most often severe-mental retardation, frequently accompanied by epilepsy and/or autism. It is characterized by the accumulation, in body fluids, of succinylaminoimidazolecarboxamide riboside and succinyladenosine, the dephosphorylated derivatives of the two substrates of the enzyme. Analysis of the ADSL gene of three unrelated patients with ADSL deficiency, in whom one of the ADSL alleles displayed a normal coding sequence, revealed a -49T-->C mutation in the 5' untranslated region of this allele. Measurements of the amount of mRNA transcribed from the latter allele showed that it was reduced to approximately 33% of that transcribed from the alleles mutated in their coding sequence. Further investigations showed that the -49T-->C mutation provokes a reduction to 25% of wild-type control of promoter function, as evaluated by luciferase activity and mRNA level in transfection experiments. The mutation also affects the binding of nuclear respiratory factor 2 (NRF-2), a known activator of transcription, as assessed by gel-shift studies. Our findings indicate that a mutation of a regulatory region of the ADSL gene might be an unusually frequent cause of ADSL deficiency, and they suggest a role for NRF-2 in the gene regulation of the purine biosynthetic pathway.  (+info)

Splicing graphs and EST assembly problem. (7/51)

MOTIVATION: The traditional approach to annotate alternative splicing is to investigate every splicing variant of the gene in a case-by-case fashion. This approach, while useful, has some serious shortcomings. Recent studies indicate that alternative splicing is more frequent than previously thought and some genes may produce tens of thousands of different transcripts. A list of alternatively spliced variants for such genes would be difficult to build and hard to analyse. Moreover, such a list does not show the relationships between different transcripts and does not show the overall structure of all transcripts. A better approach would be to represent all splicing variants for a given gene in a way that captures the relationships between different splicing variants. RESULTS: We introduce the notion of the splicing graph that is a natural and convenient representation of all splicing variants. The key difference with the existing approaches is that we abandon the linear (sequence) representation of each transcript and replace it with a graph representation where each transcript corresponds to a path in the graph. We further design an algorithm to assemble EST reads into the splicing graph rather than assembling them into each splicing variant in a case-by-case fashion.  (+info)

The characterization of mutant Bacillus subtilis adenylosuccinate lyases corresponding to severe human adenylosuccinate lyase deficiencies. (8/51)

Adenylosuccinate lyase is a homotetramer that catalyzes two discrete reactions in the de novo synthesis of purines: the cleavage of adenylosuccinate and succinylaminoimidazole carboxamide ribotide (SAICAR). Several point mutations in the gene encoding the enzyme have been implicated in human disease. Bacillus subtilis adenylosuccinate lyase was used as a model system in which mutations were constructed corresponding to those mutations associated with severe human adenylosuccinate lyase deficiency. Site-directed mutagenesis was utilized to construct amino acid substitutions in B. subtilis adenylosuccinate lyase; Met(10), Ile(123), and Thr(367) were replaced by Leu, Trp, and Arg, respectively, and the altered enzymes were expressed in Escherichia coli. These purified enzymes containing amino acid substitutions were found to have substantial catalytic activity and exhibit relatively small changes in their kinetic parameters. The major deviations from the wild-type-like behavior were observed upon biophysical characterization. All of these enzymes with amino acid replacements are associated with marked thermal instability. I123W adenylosuccinate lyase exhibits notable changes in the circular dichroism spectra, and a native gel electrophoresis pattern indicative of some protein aggregation. T367R also exhibits alterations at the quarternary level, as reflected in native gel electrophoresis. Experimental results, combined with homology modeling, suggest that the altered enzymes are primarily structurally impaired. The enzyme instability was found to be lessened by subunit complementation with the wild-type enzyme, under mild conditions; these studies may have implications for the in vivo behavior of adenylosuccinate lyase in heterozygous patients. Residues Met(10), Ile(123), and Thr(367) appear to be located in regions of the enzyme important for maintaining the structural integrity required for a stable, functional enzyme.  (+info)

Adenylosuccinate lyase (ASL) catalyzes 2 reactions in the de novo synthesis of purine nucleotides. In humans, point mutations of this enzyme are associated with mental retardation, autism, and muscle wasting. The sequence of B. subtilis ASL is 27% identical and 17% similar to the human enzyme. We have cloned, expressed, and purified B. subtilis ASL; the crystal structure of a 73% homologous bacterial enzyme is known (PDB #lc3u). We separately mutated 2 amino acids in the B. subtilis ASL (M10L & N276C) equivalent to the mutations identified in human ASL deficiency (M26L & R303C). The purified M10L and N276C possess specific activities of 0.86 and 0.38 units/mg, respectively, as compared to 1.56 units/mg for wild type (WT) enzyme. Both enzymes are similar to WT in conformation and oligomeric state as indicated by circular dichroism and light scattering. The Km for adenylosuccinate (SAMP) is not appreciably different between M1OL (5.6 uM) and WT (4.9 uM); and the pH dependence of Vmax is also ...

While the package does not explicitly say that up to speeds are to be outlawed, a statement by Neelie Kroes suggests that this may be the intent no more up to 30 Megabit deals that in practice just offer 3. The UK already has broadband speeds code of practice but it is voluntary and this new set of rules are defining rights enshrined in law. So what actual data speeds really means is important, but for now that is anyones guess, the existing UK code of practice may be enough, but be compulsory rather than voluntary. Certainly the UK moving to a gaining provider led system for migrations in 2015 ticks the switching box.. We know many who will applaud the end to up to speeds since it will expose real performance of ADSL and VDSL2 based services, but it will also make life harder for the various fixed speed connection services such as cable and FTTH/FTTP/FTTB, since contention and shared access on the backhaul networks is the sole reason that mortals can afford broadband connections at ...

17α-hydroxylase/17,20-lyase deficiency is caused by mutations in the CYP17A1 gene. The protein produced from this gene is involved in the formation of steroid hormones. This group of hormones includes sex hormones such as testosterone and estrogen, which are needed for normal sexual development and reproduction; mineralocorticoids, which help regulate the bodys salt and water balance; and glucocorticoids, which are involved in maintaining blood sugar levels and regulating the bodys response to stress.. Steroid hormones are produced through a series of chemical reactions. The CYP17A1 enzyme performs two important reactions in this process. The enzyme has 17 alpha(α)-hydroxylase activity, which is important for production of glucocorticoids and sex hormones. CYP17A1 also has 17,20-lyase activity, which is integral to the production of sex hormones.. 17α-hydroxylase/17,20-lyase deficiency results from a shortage (deficiency) of both enzyme activities.

An improved discrete multi-tone transmission scheme is describe that contemplates encoding digital data and modulating the encoded data onto a discrete multi-tone signal having a total bandwidth of at least 1.6 MHz. The modulation system is capable of dynamically updating the subcarriers used and the amount of data transmitted on each subcarrier during transmission in order to accommodate real time changes in the line quality over particular subcarriers. In one preferred embodiment of the invention the multi-tone encoding and modulation is done in substantial compliance with the ATIS North American Asymmetric Digital Subscriber Lines standard although a total of 512 subchannels each having a bandwidth of approximately 4.3125 kHz are used. In this system, the subchannels that occur at frequencies above those set forth in the standard are treated similarly to those within the standard range in terms of subcarrier selection criteria. This embodiment contemplates the use of a discrete multi-tone signal
Now listen up people. I really dont want to do the Costanza Award this year…Im running out of quotes and I have no more Costanza pictures to use. But if we have a repeat performance of this past weekend you will give me no choice. And Im just warning you now if the Costanza Award comes back he will not be happy. I mean seriously….this was a real shit show this weekend. Here are some lowlights: Flacco 34 points, Trent Edwards 22 points, Roy E. Williams 15.5 points, Thomas Jones 27 points, Tony Romo 37 points, and Fred Jackson 21.5 points. What do these guys all have in common? All of them were on the bench and outscored their starting teammates by 14 points or more! Not the way you want to start the year kids ...
Which should give you the revision number of your modem. If your modem is revision 0 or 2 you will need the KQD6_3.012 file. If your modem is revision 4, then you will require the ZZZL_3.012 file. Both of these files can be located in this tarball here. You will, later, need the firmware-extractor too, which can be found here. Finally you should check this page to find out the VPI/VCI numbers for your country or ISP. Now you have everything, save a copy of this guide too (in text helps), and copy everything to a USB flash drive, floppy disk (if it fits), or a USB external hard drive, so you can use them while offline. NOTE: Unzip isnt supported in a basic Arch Linux installation, you should unzip any .zip files using another computer or operating system first. ...
