Cloning and over-expression of thermostable Bacillus sp. YM55-1 aspartase and site-directed mutagenesis for probing a catalytic residue. (1/36)

A thermostable aspartase gene (aspB) from Bacillus sp. YM55-1 was cloned and the gene sequenced. The aspB gene (1407 bp ORF) encodes a protein with a molecular mass of 51 627 Da, consisting of 468 amino-acid residues. An amino-acid sequence comparison revealed that Bacillus YM55-1 aspartase shared 71% homology with Bacillus subtilis aspartase and 49% with Escherichia coli and Pseudomonas fluorescens aspartases. The E. coli TK237/pUCASPB strain, which was obtained by transforming E. coli TK237 (aspartase-null strain) with a vector plasmid (pUCASPB) containing the cloned aspB gene, produced a large amount of the enzyme corresponding to > 10% of the total soluble protein. The over-expressed recombinant enzyme (native molecular mass: 200 kDa) was purified effectively and rapidly using heat treatment and affinity chromatography. In order to probe the catalytic residues of this enzyme, two conserved amino-acid residues, Lys183 and His134, were individually mutated to alanine. Although the tertiary structure of each mutant was estimated to be the same as that of wild-type aspartase in CD and fluorescence measurements, the Lys183Ala mutant lost its activity completely, whereas His134Ala retained full activity. This finding suggests that Lys183 may be involved in the catalytic activity of this thermostable Bacillus YM55-1 aspartase.  (+info)

A monomeric L-aspartase obtained by in vitro selection. (2/36)

By mimicking the partial spatial structure of the dimer of the l-aspartase subunit, the central ten-helix bundle, and an "active site" between the cleft of domain 1 (D1) and domain 3 (D3) from different subunits, we designed l-aspartase variants, in which D1D2 and D2D3 were ligated with a random hexapeptide loop. As expected, we obtained the variant with the highest activity (relative activity is 21.3% of the native enzyme, named as drAsp017) by in vitro selection. The molecular weight of this variant, obtained from size-exclusion column chromatography, is about 81 kDa, which indicates that it is indeed a monomer, whereas native l-aspartase is a tetramer. The activity-reversibility of drAsp017 (10(-7) m) was 80% after incubation for 30 min at 50 degrees C, while native enzyme only retained about 17% under the same conditions. Reactivation of drAsp017 denatured in 4 m guanidine HCl was independent of protein concentration at up to 20 x 10(-8) m at 25 degrees C, whereas the protein concentration of native enzyme strongly affected its reactivation under the above conditions. The sensitivity of drAsp017 (10(-7) m) to effective factors in the fumarate-amination reaction compared with native enzyme was also determined. Half-saturating concentrations of the activator l-aspartate and Mg2+ for drAsp017 (0.8 and 0.5 mm, respectively) are much higher than that of the native enzyme (0.10 and 0.15 mm, respectively). The data show that a monomeric l-aspartase is obtained by in vitro selection. Thus, the conversion of oligomeric proteins into their functional monomers could have important applications.  (+info)

Thermostable aspartase from a marine psychrophile, Cytophaga sp. KUC-1: molecular characterization and primary structure. (3/36)

We found that a psychrophilic bacterium isolated from Antarctic seawater, Cytophaga sp. KUC-1, abundantly produces aspartase [EC4.3.1.1], and the enzyme was purified to homogeneity. The molecular weight of the enzyme was estimated to be 192,000, and that of the subunit was determined to be 51,000: the enzyme is a homotetramer. L-Aspartate was the exclusive substrate. The optimum pH in the absence and presence of magnesium ions was determined to be pH 7.5 and 8.5, respectively. The enzyme was activated cooperatively by the presence of L-aspartate and by magnesium ions at neutral and alkaline pHs. In the deamination reaction, the K(m) value for L-aspartate was 1.09 mM at pH 7.0, and the S(1/2) value was 2.13 mM at pH 8.5. The V(max) value were 99.2 U/mg at pH 7.0 and 326 U/mg at pH 8.5. In the amination reaction, the K(m) values for fumarate and ammonium were 0.797 and 25.2 mM, respectively, and V(max) was 604 U/mg. The optimum temperature of the enzyme was 55 degrees C. The enzyme showed higher pH and thermal stabilities than that from mesophile: the enzyme was stable in the pH range of 4.5-10.5, and about 80% of its activity remained after incubation at 50 degrees C for 60 min. The gene encoding the enzyme was cloned into Escherichia coli, and its nucleotides were sequenced. The gene consisted of an open reading frame of 1,410-bp encoding a protein of 469 amino acid residues. The amino acid sequence of the enzyme showed a high degree of identity to those of other aspartases, although these enzymes show different thermostabilities.  (+info)

Possible physiological roles of aspartase, NAD- and NADP-requiring glutamate dehydrogenases of Pseudomonas fluorescens. (4/36)

The levels of aspartase, NADP- and NAD-requiring glutamate dehydrogenases (GDHs) in Pseudomonas fluorescens grown under various nutritional conditions were determined. NADP-GDH showed the highest value on glucose-ammonium sulfate medium and markedly lower values on amino-acid and casamino-acids media, while the reverse was found for the NAD-GDH, as in the case of other microorganisms with two GDHs. Aspartase did not show a marked variation between the media examined. Glucose nutritionally induced NADP-GDH but suppressed NAD-GDH; and it had no effect on aspartase, which was slightly induced by casamino acids. Transfer of the cells grown on glucose-ammonium sulfate medium to casamino-acids medium clearly increased the levels of NAD-GDH and aspartase, while addition of chloramphenicol to the media abolished the increases, suggesting that the increases were due to de novo synthesis of the enzyme proteins. These results indicate that the aspartase of this microorganism has a different function from those in others, including Escherichia coli.  (+info)

Enzymes involved in anaerobic respiration appear to play a role in Actinobacillus pleuropneumoniae virulence. (5/36)

Actinobacillus pleuropneumoniae, the etiological agent of porcine pleuropneumonia, is able to survive on respiratory epithelia, in tonsils, and in the anaerobic environment of encapsulated sequesters. It was previously demonstrated that a deletion of the anaerobic dimethyl sulfoxide reductase gene (dmsA) results in attenuation in acute disease (N. Baltes, S. Kyaw, I. Hennig-Pauka, and G. F. Gerlach, Infect. Immun. 71:6784-6792, 2003). In the present study, using two-dimensional polyacrylamide gel electrophoresis and quadrupole time-of-flight mass spectrometry, we identified an aspartate ammonia-lyase (AspA) which is upregulated upon induction with bronchoalveolar lavage fluid (BALF). This enzyme is involved in the production of fumarate, an alternative electron acceptor under anaerobic conditions. The coding gene (aspA) was cloned and shown to be present in all A. pleuropneumoniae serotype reference strains. The transcriptional start point was identified downstream of a putative FNR binding motif, and BALF-dependent activation of aspA was confirmed by construction of an isogenic A. pleuropneumoniae mutant carrying a chromosomal aspA::luxAB transcriptional fusion. Two aspA deletion mutants, A. pleuropneumoniae DeltaaspA and A. pleuropneumoniae DeltaaspADeltadmsA, were constructed, both showing reduced growth under anaerobic conditions in vitro. Pigs challenged with either of the two mutants in an aerosol infection model showed a lower lung lesion score than that of the A. pleuropneumoniae wild-type (wt) controls. Pigs challenged with A. pleuropneumoniae DeltaaspADeltadmsA had a significantly lower clinical score, and this mutant was rarely reisolated from unaltered lung tissue; in contrast, A. pleuropneumoniae DeltaaspA and the A. pleuropneumoniae wt were consistently reisolated in high numbers. These results suggest that enzymes involved in anaerobic respiration are necessary for the pathogen's ability to persist on respiratory tract epithelium and play an important role in A. pleuropneumoniae pathogenesis.  (+info)

Deletion of the anaerobic regulator HlyX causes reduced colonization and persistence of Actinobacillus pleuropneumoniae in the porcine respiratory tract. (6/36)

Actinobacillus pleuropneumoniae, the etiological agent of porcine pleuropneumonia, is able to persist on respiratory epithelia, in tonsils, and in the anaerobic environment of encapsulated lung sequesters. We have demonstrated previously that putative HlyX-regulated genes, coding for dimethyl sulfoxide (DMSO) reductase and aspartate ammonia lyase, are upregulated during infection and that deletions in these genes result in attenuation of the organism. The study presented here investigates the role of HlyX, the fumarate nitrate reductase regulator (FNR) homologue of A. pleuropneumoniae. By constructing an isogenic A. pleuropneumoniae hlyX mutant, the HlyX protein is shown to be responsible for upregulated expression of both DMSO reductase and aspartate ammonia lyase (AspA) under anaerobic conditions. In a challenge experiment the A. pleuropneumoniae hlyX mutant is shown to be highly attenuated, unable to persist in healthy lung epithelium and tonsils, and impaired in survival inside sequestered lung tissue. Further, using an A. pleuropneumoniae strain carrying the luxAB genes as transcriptional fusion to aspA on the chromosome, the airway antioxidant glutathione was identified as one factor potentially responsible for inducing HlyX-dependent gene expression of A. pleuropneumoniae in epithelial lining fluid.  (+info)

Cloning, nucleotide sequence, and expression of the Bacillus subtilis ans operon, which codes for L-asparaginase and L-aspartase. (7/36)

L-Aspartase was purified from Bacillus subtilis, its N-terminal amino acid sequence was determined to construct a probe for the aspartase gene, and the gene (termed ansB) was cloned and sequenced. A second gene (termed ansA) was found upstream of the ansB gene and coded for L-asparaginase. These two genes were in an operon designated the ans operon, which is 80% cotransformed with the previously mapped aspH1 mutation at 215 degrees. Primer extension analysis of in vivo ans mRNA revealed two transcription start sites, depending on the growth medium. In wild-type cells in log-phase growth in 2x YT medium (tryptone-yeast extract rich medium), the ans transcript began at -67 relative to the translation start site, while cells in log-phase growth or sporulating (t1 to t4) in 2x SG medium (glucose nutrient broth-based moderately rich medium) had an ans transcript which began at -73. The level of the -67 transcript was greatly increased in an aspH mutant grown in 2x YT medium; the -67 transcript also predominated when this mutant was grown in 2x SG medium, although the -73 transcript was also present. In vitro transcription of the ans operon by RNA polymerase from log-phase cells grown in 2x YT medium and log-phase or sporulating cells grown in 2x SG medium yielded only the -67 transcript. Depending on the growth medium, the levels of asparaginase and aspartase were from 2- to 40-fold higher in an aspH mutant than in wild-type cells, and evidence was obtained indicating that the gene defined by the aspH1 mutation codes for a trans-acting transcriptional regulatory factor. In wild-type cells grown in 2x SG medium, the levels of both aspartase and asparaginase decreased significantly by t0 of sporulation but then showed a small increase, which was mirrored by changes in the level of beta-galactosidase from an ansB-lacZ fusion. The increase in the activities of ans operon enzymes between t2 and t5 of sporulation was found primarily in the forespore, and the great majority of the increased was found in the mature spore. However, throughout sporulation the only ans transcript detected was the -73 form, and no sporulation-specific RNA polymerase tested yielded a -73 transcript in vitro.  (+info)

The nucleotide sequences of two segments of DNA (2250 and 2921 base-pairs) containing the functionally related fumarase (fumC) and aspartase (aspA) genes of Escherichia coli K12 were determined. The fumC structural gene comprises 1398 base-pairs (466 codons, excluding the initiation codon), and it encodes a polypeptide of Mr 50353 that resembles the fumarases of Bacillus subtilis 168 (citG-gene product), rat liver and pig heart. The fumC gene starts 140 base-pairs downstream of the structurally-unrelated fumA gene, but there is no evidence that both genes form part of the same operon. The aspA structural gene comprises 1431 base-pairs (477 codons excluding the initiation codon), and it encodes a polypeptide of Mr 52190, similar to that predicted from maxicell studies and for the enzyme from E. coli W. Remarkable homologies were found between the primary structures of the fumarase (fumC and citG) and aspartase (aspA) genes and their products, suggesting close structural and evolutionary ...

Emed - PeriNAAEmed - PeriNAA
Canavan disease (CD) is a rare leukodystrophy caused by mutations in the ASPA gene, leading to severe neurodegeneration and short life expectancy. To date, the exact disease mechanism is poorly understood and therapeutic options are scarce. The ASPA gene encodes aspartoacylase, an enzyme catalyzing the degradation of N-acetylaspartate (NAA). Despite NAA being the second-most abundant metabolite in the mammalian brain, its functional role is poorly understood. Recently, several independent groups found NAA metabolism to also play important roles in non-nervous tissues, e.g. in adipocytes, immune cells, lung and prostate cancer cells, pointing towards a previously overlooked wide relevance of peripheral NAA metabolism.. In the PeriNAA junior research alliance, clinical, experimental and computational groups are collaborating to generate a computational model around NAA metabolism and inferring model parameters from stable isotope-assisted metabolomics data, RNA-seq data, and other experimental ...

While I understand the obsession, I think many photographers over use it to compensate for their lack of compositional skills and its easy. Just shoot wide open and forget about it.. Photography is about contrasts, its about give and take. And bokeh is also dependent on what is in focus in the image.

Thoughts from IETF 109 | APNIC BlogThoughts from IETF 109 | APNIC Blog
One of the presentations of interest in SIDR OPS WG was on the efforts to perform some form of AS Path validation using the Autonomous System Provider Authorization (ASPA) objects.. This is a variation of the earlier soBGP AS adjacency object, where with ASPAs topological AS adjacency is combined with inter-AS policy. It relies on a coarse taxonomy of inter-AS relationships where, within a particular routed protocol, two ASes can either be peers to each other or one can be a provider for the other. In the ASPA framework, each customer AS lists the complete set of providers that are authorized to propagate routes that this AS has passed to it as a provider.. If you assume that no AS is willing to incur costs on behalf of non-customer AS neighbors, then we can arrive at the valley-free view of AS Paths. If you think about AS Paths as an ordered sequence of paired relationships, and we use the concept of elevation to describe the customer-provider relationship, then we can define a policy ...

Tom Abrahamsson on 35mm LSM lenses
35/1,4 Leica Aspheric: Used to be the bench mark lens for fast 35s. I have had mine since it was announced long time ago. Very sharp and contrasty, but not very well corrected for flare. Mine went back to Solms for a rebuild in 1998 after it started to flare badly enough to be useless. I never got an explanation what had happened, but after 6 months it was back in my hands and has behaved well ever since. Still you have to watch for strong lights at the edges. Wide-open performance is very good, sharp and contrasty, but that also means some burning and dodging when printing black/white as the contrast is almost too high. Less dramatic drop-off of sharpness than the 35/1,2 and a fairly unpleasant Bokeh. It almost looks like digital pixilation and lacks smoothness. The 35/1,4 Asph. weighs less than the 35/1,2, but not by much and it is a bit smaller. However, it does have a focusing tab which makes it quick to focus. I am not sure that the benefits of the 35/1,2 outweighs those of the 35/1,4 ...

diglloyd blog: Leica 35mm f/1.4 Summilux-M ASPH examples added to Leica M9 guide
Geologist Edo V writes:. Striations are scratches into rock surfaces, made by ice (containing rocks), or inside rocks on fault planes (strict geological use of the word). I do not see them in your photo.. The orange and gray bands run down the dip of the rock surface and are probably due to water run-off (melting snow?).. The two bands that run nearly vertical in the photo are intruded sheets (dikes) of late-stage magma, probably aplitic dikes.. The NW-SE bands in the photo are edges of exfoliation sheets, layers of granite that peel off due to repeated expansion and shrinkage with temperature variations and freezing.. You are in good company. Ansel Adams has photo of a rock surface with magmatic inclusions, with dark rims which he described as shadows, but they seem to be magmatic selvedges, which are rims of dark minerals that surround the magmatic inclusions, foreign rocks which sink into a magmatic chamber from the roof of an intrusion.

Production of L-aspartic acid by biotransformation and recovery using reverse micelle and gas hydrate methods | AVESİSProduction of L-aspartic acid by biotransformation and recovery using reverse micelle and gas hydrate methods | AVESİS
L-Aspartic acid (L-Asp) was produced using Escherichia coli (ATCC 11303), and its recovery from the reaction mixture was studied using reverse micelle and gas hydrate methods. The effect of initial substrate concentration on L-Asp production was also investigated, and inhibition was shown to occur above 0.75 mol L-1. The values of the kinetic constants were determined as r(max) = 2.33 x 10(-4) mol L-1 min(-1), K-M = 0.19 mol L-1, and K-ss = 3.98 mol L-1. The reverse micelle phase used for extraction contained Aliquat-336, 1-decanol and isooctane, and a micro-injection technique was used for extraction of L-Asp. The reverse micelle system is a useful technique for obtaining small particle sizes, which can be used for the synthesis of nanoparticle biomolecules. Recovery of L-Asp from reverse micelles using CO2 hydrates was carried out, giving a recovery of 55%. The formation of CO2 hydrate from the reverse micelle solution breaks the micelle by reducing the amount of water in the micelle ...

Ultra-sensitive electrochemical on-line determination of Clarithromycin based on Poly(L-Aspartic Acid)/Graphite Oxide/Pristine...Ultra-sensitive electrochemical on-line determination of Clarithromycin based on Poly(L-Aspartic Acid)/Graphite Oxide/Pristine...
In this work, a novel and extra sensitive method for on-line continues monitoring of Clarithromycin in whole blood sample was introduced based on coupling of electro-membrane extraction (EME) and stripping fast Fourier transform continuous cyclic voltammetry (SFFTCCV). In this method, the potential waveform was continuously applied on a Poly(L-Aspartic Acid)/Graphite Oxide/Pristine Graphene/Glassy Carbon Electrode and the electrode response was obtained by detracting the background current and in the following integrating the current in the specific potential range of oxidation of the analyte. This method was performed by applying a DC potential and migration of Clarithromycin from the sample solution into a layer of 4-methyl-2-pentanol that is immobilized in the pores of the sheet membrane and then migration into the acceptor solution. A low and valuable detection limit of 1.0 ng ml-1 and quantification limit of 6.0 ng ml-1 are considered as a part of the sensible results of this experiment.

Brexit: A boon or a curse for animals used in scientific procedures? - Northumbria Research LinkBrexit: A boon or a curse for animals used in scientific procedures? - Northumbria Research Link
The UK has long been hailed as one of the world leaders in animal welfare. Within the UK, animals used in experiments are provided some protection under the Animals (Scientific Procedures) Act 1986 (ASPA). This Act was impacted by European Union (EU) Directive 2010/63/EU, and subsequently the ASPA was updated to reflect any changes required. While the Directive is very similar to the protection the UK already afforded to animals used in experiments, there were some advances that the Directive provided that were not present in the ASPA. On paper, the changes introduced were promising but may not have been achieved in practice. In 2016, the British public voted to leave the EU, which presented concerns over animal welfare protection and legislation provided by EU law. With the completion of Brexit, there may be an opportunity to diverge from the Directive to advance protection for animals used in experiments. This article explores the influence that the EU has had on animal experimentation in the ...
