NADH-glutamate synthase in alfalfa root nodules. Genetic regulation and cellular expression. (1/1399)

NADH-dependent glutamate synthase (NADH-GOGAT; EC is a key enzyme in primary nitrogen assimilation in alfalfa (Medicago sativa L.) root nodules. Here we report that in alfalfa, a single gene, probably with multiple alleles, encodes for NADH-GOGAT. In situ hybridizations were performed to assess the location of NADH-GOGAT transcript in alfalfa root nodules. In wild-type cv Saranac nodules the NADH-GOGAT gene is predominantly expressed in infected cells. Nodules devoid of bacteroids (empty) induced by Sinorhizobium meliloti 7154 had no NADH-GOGAT transcript detectable by in situ hybridization, suggesting that the presence of the bacteroid may be important for NADH-GOGAT expression. The pattern of expression of NADH-GOGAT shifted during root nodule development. Until d 9 after planting, all infected cells appeared to express NADH-GOGAT. By d 19, a gradient of expression from high in the early symbiotic zone to low in the late symbiotic zone was observed. In 33-d-old nodules expression was seen in only a few cell layers in the early symbiotic zone. This pattern of expression was also observed for the nifH transcript but not for leghemoglobin. The promoter of NADH-GOGAT was evaluated in transgenic alfalfa plants carrying chimeric beta-glucuronidase promoter fusions. The results suggest that there are at least four regulatory elements. The region responsible for expression in the infected cell zone contains an 88-bp direct repeat.  (+info)

The mechanism of rhythmic ethylene production in sorghum. The role of phytochrome B and simulated shading. (2/1399)

Mutant sorghum (Sorghum bicolor [L.] Moench) deficient in functional phytochrome B exhibits reduced photoperiodic sensitivity and constitutively expresses a shade-avoidance phenotype. Under relatively bright, high red:far-red light, ethylene production by seedlings of wild-type and phytochrome B-mutant cultivars progresses through cycles in a circadian rhythm; however, the phytochrome B mutant produces ethylene peaks with approximately 10 times the amplitude of the wild type. Time-course northern blots show that the mutant's abundance of the 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase mRNA SbACO2 is cyclic and is commensurate with ethylene production, and that ACC oxidase activity follows the same pattern. Both SbACO2 abundance and ACC oxidase activity in the wild-type plant are very low under this regimen. ACC levels in the two cultivars did not demonstrate fluctuations coincident with the ethylene produced. Simulated shading caused the wild-type plant to mimic the phenotype of the mutant and to produce high amplitude rhythms of ethylene evolution. The circadian feature of the ethylene cycle is conditionally present in the mutant and absent in the wild-type plant under simulated shading. SbACO2 abundance in both cultivars demonstrates a high-amplitude diurnal cycle under these conditions; however, ACC oxidase activity, although elevated, does not exhibit a clear rhythm correlated with ethylene production. ACC levels in both cultivars show fluctuations corresponding to the ethylene rhythm previously observed. It appears that at least two separate mechanisms may be involved in generating high-amplitude ethylene rhythms in sorghum, one in response to the loss of phytochrome B function and another in response to shading.  (+info)

Identification of D-proline reductase from Clostridium sticklandii as a selenoenzyme and indications for a catalytically active pyruvoyl group derived from a cysteine residue by cleavage of a proprotein. (3/1399)

Highly active D-proline reductase was obtained from Clostridium sticklandii by a modified purification scheme. The cytoplasmic enzyme had a molecular mass of about 870 kDa and was composed of three subunits with molecular masses of 23, 26, and 45 kDa. The 23-kDa subunit contained a carbonyl group at its N terminus, which could either be labeled with fluorescein thiosemicarbazide or removed by o-phenylenediamine; thus, N-terminal sequencing became feasible for this subunit. L-[14C]proline was covalently bound to the 23-kDa subunit if proline racemase and NaBH4 were added. Selenocysteine was detected in the 26-kDa subunit, which correlated with an observed selenium content of 10.6 g-atoms in D-proline reductase. No other non-proteinaceous cofactor was identified in the enzyme. A 4.8-kilobase pair (kb) EcoRI fragment was isolated and sequenced containing the two genes prdA and prdB. prdA coding for a 68-kDa protein was most likely translated as a proprotein that was posttranslationally cleaved at a threonine-cysteine site to give the 45-kDa subunit and most probably a pyruvoyl-containing 23-kDa subunit. The gene prdB encoded the 26-kDa subunit and contained an in frame UGA codon for selenocysteine insertion. prdA and prdB were transcribed together on a transcript of 4.5 kb; prdB was additionally transcribed as indicated by a 0.8-kb mRNA species.  (+info)

Substrate-specific selenoprotein B of glycine reductase from Eubacterium acidaminophilum. Biochemical and molecular analysis. (4/1399)

The substrate-specific selenoprotein B of glycine reductase (PBglycine) from Eubacterium acidaminophilum was purified and characterized. The enzyme consisted of three different subunits with molecular masses of about 22 (alpha), 25 (beta) and 47 kDa (gamma), probably in an alpha 2 beta 2 gamma 2 composition. PBglycine purified from cells grown in the presence of [75Se]selenite was labeled in the 47-kDa subunit. The 22-kDa and 47-kDa subunits both reacted with fluorescein thiosemicarbazide, indicating the presence of a carbonyl compound. This carbonyl residue prevented N-terminal sequencing of the 22-kDa (alpha) subunit, but it could be removed for Edman degradation by incubation with o-phenylenediamine. A DNA fragment was isolated and sequenced which encoded beta and alpha subunits of PBglycine (grdE), followed by a gene encoding selenoprotein A (grdA2) and the gamma subunit of PBglycine (grdB2). The cloned DNA fragment represented a second GrdB-encoding gene slightly different from a previously identified partial grdBl-containing fragment. Both grdB genes contained an in-frame UGA codon which confirmed the observed selenium content of the 47-kDa (gamma) subunit. Peptide sequence analyses suggest that grdE encodes a proprotein which is cleaved into the previously sequenced N-terminal 25-kDa (beta) subunit and a 22-kDa (alpha) subunit of PBglycine. Cleavage most probably occurred at an -Asn-Cys- site concomitantly with the generation of the blocking carbonyl moiety from cysteine at the alpha subunit.  (+info)

Structural characterization of l-aspartate oxidase and identification of an interdomain loop by limited proteolysis. (6/1399)

l-Aspartate oxidase is the first enzyme in the de novo biosynthesis of pyridinic coenzymes in facultative aerobic organisms. The enzyme is FAD dependent and it shares common features with both the oxidase and the fumarate reductase classes of flavoproteins. In this report we focused our attention on the supersecondary structure of the molecule by means of limited proteolysis studies. Moreover the polymerization state of the protein at different pH and the interactions with NAD and its analogues are described. The results suggest that l-aspartate oxidase is a monomer at pH values lower than 4.5 and a dimer at pH values higher than 6.5. The protein is organized in two major domains connected by a flexible loop located in the 120-140 region. The data obtained by limited proteolysis of the holo and the apo form in the presence and in the absence of substrates (fumarate and menadione), inhibitors (succinate) and NAD allows the proposition that both domains are involved in the binding of the flavin coenzyme. Moreover the data reported in this manuscript suggest that NAD inhibits l-aspartate oxidase activity by competing with the flavin for the binding to the enzyme.  (+info)

Control of expression of one-carbon metabolism genes of Saccharomyces cerevisiae is mediated by a tetrahydrofolate-responsive protein binding to a glycine regulatory region including a core 5'-CTTCTT-3' motif. (7/1399)

Expression of yeast genes involved in one-carbon metabolism is controlled by glycine, by L-methionine, and by nitrogen sources. Here we report a novel control element containing a core CTTCTT motif mediating the glycine response, demonstrating that a protein binds this element, that binding is modulated by tetrahydrofolate, and that folate is required for the in vivo glycine response. In an heterologous CYC1 promoter the region needed for the glycine response of GCV2 (encoding the P-subunit of glycine decarboxylase) mediated repression that was relieved by glycine. It was also responsible for L-methionine control but not nitrogen repression. GCV1 and GCV3 have an homologous region in their promoters. The GCV1 region conferred a glycine response on an heterologous promoter acting as a repressor or activator depending on promoter context. A protein was identified that bound to the glycine regulatory regions of GCV1 and GCV2 only if the CTTCTT motif was intact. This protein protected a 17-base pair CATCN7CTTCTT region of GCV2 that is conserved between GCV1 and GCV2. Protein binding was increased by tetrahydrofolate, and use of a fol1 deletion mutant indicated the involvement of a folate in the in vivo glycine response. Tetrahydrofolate or a derivative may act as a ligand for the transcription factor controlling expression of one-carbon metabolism genes.  (+info)

Purification of beef kidney D-aspartate oxidase overexpressed in Escherichia coli and characterization of its redox potentials and oxidative activity towards agonists and antagonists of excitatory amino acid receptors. (8/1399)

The flavoenzyme d-aspartate oxidase from beef kidney (DASPO, EC 1.4. 3.1) has been overexpressed in Escherichia coli. A purification procedure, faster than the one used for the enzyme from the natural source (bDASPO), has been set up yielding about 2 mg of pure recombinant protein (rDASPO) per each gram of wet E. coli paste. rDASPO has been shown to possess the same general biochemical properties of bDASPO, except that the former contains only FAD, while the latter is a mixture of two forms, one active containing FAD and one inactive containing 6-OH-FAD (9-20% depending on the preparation). This results in a slightly higher specific activity (about 15%) for rDASPO compared to bDASPO and in facilitated procedures for apoprotein preparation and reconstitution. Redox potentials of -97 mV and -157 mV were determined for free and l-(+)-tartrate complexed DASPO, respectively, in 0.1 M KPi, pH 7.0, 25 degrees C. The large positive shift in the redox potential of the coenzyme compared to free FAD (-207 mV) is in agreement with similar results obtained with other flavooxidases. rDASPO has been used to assess a possible oxidative activity of the enzyme towards a number of compounds used as agonists or antagonists of neurotransmitters, including d-aspartatic acid, d-glutamic acid, N-methyl-d-aspartic acid, d,l-cysteic acid, d-homocysteic acid, d, l-2-amino-3-phosphonopropanoic acid, d-alpha-aminoadipic acid, d-aspartic acid-beta-hydroxamate, glycyl-d-aspartic acid and cis-2, 3-piperidine dicarboxylic acid. Kinetic parameters for each substrate in 50 mM KPi, pH 7.4, 25 degrees C are reported.  (+info)

The active site and substrate-binding mode of MD-ACO1 (Malus domestica Borkh. 1-aminocyclopropane-1-carboxylate oxidase) have been determined using site-directed mutagenesis and comparative modelling methods. The MD-ACO1 protein folds into a compact jelly-roll motif comprised of eight α-helices, 12 β-strands and several long loops. The active site is well defined as a wide cleft near the C-terminus. The co-substrate ascorbate is located in cofactor Fe2+-binding pocket, the so-called 2-His-1-carboxylate facial triad. In addition, our results reveal that Arg244 and Ser246 are involved in generating the reaction product during enzyme catalysis. The structure agrees well with the biochemical and site-directed mutagenesis results. The three-dimensional structure together with the steady-state kinetics of both the wild-type and mutant MD-ACO1 proteins reveal how the substrate specificity of MD-ACO1 is involved in the catalytic mechanism, providing insights into understanding the fruit ripening ...

The residues L40, A113, V291, and V294, in leucine dehydrogenase (LeuDH), predicted to be involved in recognition of the substrate side chain, have been mutated on the basis of the molecular modeling to mimic the substrate specificities of phenylalanine (PheDH), glutamate (GluDH), and lysine dehydrogenases (LysDH). The A113G and A113G/V291L mutants, imitating the PheDH active site, displayed activities toward -phenylalanine and phenylpyruvate with 1.6 and 7.8% of kcat values of the wild-type enzyme for the preferred substrates, -leucine and its keto-analog, respectively. Indeed, the residue A113, corresponding to G114 in PheDH, affects the volume of the side-chain binding pocket and has a critical role in discrimination of the bulkiness of the side chain. Another two sets of mutants, substituting L40 and V294 of LeuDH with the corresponding residues predicted in GluDH and LysDH, were also constructed and characterized.

To make this vision a reality, we attempted to transfer the plant ethylene biosynthesis pathway into E. coli. Plants produce ethylene through the Yang Cycle, which uses methionine as a base molecule to produce several different products. We studied the enzymes involved and designed a genetic circuit composed of SAM synthase, ACC synthase and ACC oxidase. E coli already possesses a gene for SAM synthase, so we added a second copy to our construct to ramp up production. ACC synthase and ACC oxidase are only found in plants, so we explored enzyme characterisation databases to find the most efficient and specific catalysts from the plant world. Our analysis pointed to apple for ACC synthase and tomato for ACC oxidase. With this in silico work done, our plan was to have all three genes synthesised by Mr. Gene after codon optimising them for E. coli. We would then add ribosome binding sites and link these three genes together in one construct for efficient ethylene production from E. coli. Naturally, ...

retitle 336993 initramfs done by yaird with XFS severity 336993 serious thanks I use XFS on a production system and surely I am not alone in that case, so IMHO, it is a dead serious bug. It seems the initramfs implementation is sensitive to cruft at the end of the cpio.gz file. Also, it seems like yaboot might be loading extra data and appending them to the end of the image causing the kernel to fail to unpack the image. Most probably, the issue is located in the xfs_read code of yaboot. We will investigate that... Cheers, -- ((__,--,__)) Aurélien GÉRÔME .---. `--)~ ~(--` Free Software Developer / \ .-( )`-.

XFS filesystem is fragmented into subgroups. These groups are something like smaller partitions in a bigger one. This allows kernel to use paralellism - it can write to several parts of filesystem at the same time. Offcourse, disk head will still write data in one place after another, because disks have only one head - so this technology gives benefits before data is sent to a disk. If you have too much a. groups, your FS will be divided in many sections, and then its very likely files will get fragmented in between two or even three section. Next bad thing is that when you fill up your FS, itll start to use too much CPU. Those things slows things down dramaticly... It has been tought that at least 1 a. group is needed per 4GB, but some XFS developers denied that information, and marked it as obsolete on LKML recently. So, what to choose here? Depends on how much parallelism do you really need. This thing has its benefits in server usage, but for desktop, 2 allocation groups per one CPU seems ...
Chemical exfoliation is an indispensible step in your skincare routine, credited for absolving issues that range from acne to pore troubles. Heres a guide.
In the conceptualization and planning stages of this feature we were certain it was going to be among the best coverage we have offered in regards to exfoliation. Indeed I think the information in this feature as well as the supporting articles is very informative and well written. What I know now that I didnt know before we began the process of talking to potential writers, is how difficult it would be to find four people who were willing to contribute to this feature, primarily because of the title. I can only imagine what they would have said if they had seen the cover and opening art for this feature. Their reaction might have been similar to your own and even ours when we first looked at these images - a bit shocked and taken aback. But lets stay focused, and I will get back to the art in a minute. ...

Glycine decarboxylase is a mitochondrial enzyme complex, which is the site of photorespiratory CO2 and NH3 release. Although the proteins that constitute the complex are located within the mitochondria, because of their intimate association with photosynthesis their expression is controlled by light. Comparisons of the kinetics of mRNA accumulation between the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase and the H-protein of glycine decarboxylase during the greening of etiolated Arabidopsis thaliana suggest that their expression is controlled in parallel. A genomic clone for the H-protein (gdcH) was isolated from Arabidopsis and sequenced. The upstream region from -856 to +62 was fused to the β-glucuronidase (GUS) reporter gene, and this construct was transformed into tobacco. This 5′ upstream regulatory region appears to control GUS expression in a manner very similar to that of the endogenous H-protein gene. Constructs with deletions in the 5′ upstream region were ...
Purpose: To evaluate plasma total homocysteine (tHcy) and nitric oxide (NO) marker levels in patients with pseudoexfoliation syndrome (PXS), pseudoexfoliation glaucoma (PXG), primary open-angle glaucoma (POAG), and normal controls. Methods: This cross-sectional, prospective study involved 19 patients with POAG, 18 with PXS, 22 with PXG, and 20 control subjects. Fasting tHcy levels of all study participants were determined using a fluorescence polarization immunoassay method. Quantitation of total nitrate was based on the Griess reaction, in which a chromophore with a strong absorbance at 545 nm is formed by reaction of nitrite with a mixture of naphthylethylenediamine and sulphanilamide. Results: The mean plasma homocysteine level was statistically significantly elevated in the PXS (p=0.033) and the PXG (p=0.023) groups but not in the POAG group (p=0.996) when compared with the control group. Multiple logistic regression analyses comparing the various patient groups with the single control group ...
Introduction. Bothrops pirajai snake is an endemic species from the South region of Bahia state, Brazil, and it belongs nowadays to a national list of Brazilian fauna species threatened of extinction (Martins & Molina, 2008). Its venom is rich in proteins such as phospholipases A2, desintegrins, metalloproteases, serinoproteases, L-amino acid oxidases and others (Rodrigues et al., 2009). L-amino acid oxidases (LAAO, EC are enantioselective flavoenzymes catalyzing the oxidative deamination of a wide range of L-amino acids (Stábeli et al., 2007). During the reductive half-reaction, the amino acid substrate is oxidized to the imino acid with concomitant reduction of the flavin adenine dinucleotide (FAD) cofactor. The imino acid product of oxidation undergoes a non-enzymatic hydrolysis to give the respective α-keto acid and ammonia. An oxidative half-reaction completes the catalytic cycle re-oxidizing the FAD with molecular oxygen and producing hydrogen peroxide (Moustafa et al., ...
Purpose.: We examined the association between caffeine and caffeinated beverage consumption in relation to the risk of exfoliation glaucoma or exfoliation glaucoma suspect (EG/EGS). Methods.: We followed 78,977 women from the Nurses Health Study (NHS) and 41,202 men from the Health Professionals Follow-up Study (HPFS) who were at least 40 years of age, did not have glaucoma, and reported undergoing eye examinations from 1980 (NHS) or 1986 (HPFS) to 2008. Information on consumption of caffeine-containing beverages and potential confounders were repeatedly ascertained in validated follow-up questionnaires. Confirmation with medical record review revealed 360 incident EG/EGS cases. Multivariate rate ratios (RRs) for EG/EGS were calculated in each cohort and then pooled using meta-analytic techniques. Results.: Compared with participants whose cumulatively updated total caffeine consumption was ,125 mg/day, participants who consumed ≥500 mg/day had a trend toward increased risk of EG/EGS that was ...
1.Nitric oxide is a potent vasodilator which plays a major role in the control of blood pressure. The hyperdynamic circulation of cirrhosis has been linked to nitric oxide.. 2.We measured neutrophil nitric oxide synthase activity in relation to the level of hepatic dysfunction in patients with liver disease of varying aetiology and severity.. 3.Neutrophils were isolated from 21 patients (7 Child-Pugh score A, 6 grade B and 8 grade C) aged 28-76 (median 49) years. Nitric oxide synthase activity was measured using the conversion of oxyhaemoglobin to methaemoglobin by nitric oxide and expressed in terms of cell protein. Blood pressure and biochemical indices were recorded. Data were assessed using Kruskal-Wallis one-way analysis of variance, Mann-Whitney U-test or Pearson correlation as appropriate.. 4.Systolic, mean arterial and diastolic blood pressures decreased with increasing hepatic damage (P = 0.031, P = 0.01 and P = 0.038 respectively). Nitric oxide synthase activity increased with the ...

Abstract Background The identification of new serum biomarkers with high sensitivity and specificity is an important priority in pancreatic cancer research. Through an extensive proteomics analysis of pancreatic cancer cell lines and pancreatic juice, we previously generated a list of candidate pancreatic cancer biomarkers. The present study details further validation of four of our previously identified candidates: regenerating islet-derived 1 beta (REG1B), syncollin (SYCN), anterior gradient homolog 2 protein (AGR2), and lysyl oxidase-like 2 (LOXL2). Methods The candidate biomarkers were validated using enzyme-linked immunosorbent assays in two sample sets of serum/plasma comprising a total of 432 samples (Sample Set A: pancreatic ductal adenocarcinoma (PDAC, n = 100), healthy (n = 92); Sample Set B: PDAC (n = 82), benign (n = 41), disease-free (n = 47), other cancers (n = 70)). Biomarker performance in distinguishing PDAC from each control group was assessed individually in the two sample sets.

The transcriptional activator IFN regulatory factor 1 (IRF-1) and its antagonistic repressor IRF-2 are regulators of the IFN system. IRF-1 also manifests tumor suppressive activity, and its inactivation could contribute to the development of human hematopoietic malignancies. Here, we report the identification of the lysyl oxidase gene as a target gene of IRF-1. An IRF response element was identified in the lysyl oxidase gene promoter. We also demonstrate that the transformed phenotype of ras-expressing embryonic fibroblasts with a null mutation in the IRF-1 allele could be suppressed by the expression of the lysyl oxidase cDNA, implicating its potential role in tumor suppression. Thus, the regulation of the lysyl oxidase gene by IRF-1 could contribute to the multistep process of malignant transformation.. ...
