Characterization of a neutrophil cell surface glycosaminoglycan that mediates binding of platelet factor 4. (1/1431)

Platelet factor 4 (PF-4) is a platelet-derived alpha-chemokine that binds to and activates human neutrophils to undergo specific functions like exocytosis or adhesion. PF-4 binding has been shown to be independent of interleukin-8 receptors and could be inhibited by soluble chondroitin sulfate type glycosaminoglycans or by pretreatment of cells with chondroitinase ABC. Here we present evidence that surface-expressed neutrophil glycosaminoglycans are of chondroitin sulfate type and that this species binds to the tetrameric form of PF-4. The glycosaminoglycans consist of a single type of chain with an average molecular mass of approximately 23 kDa and are composed of approximately 85-90% chondroitin 4-sulfate disaccharide units type CSA (-->4GlcAbeta1-->3GalNAc(4-O-sulfate)beta1-->) and of approximately 10-15% di-O-sulfated disaccharide units. A major part of these di-O-sulfated disaccharide units are CSE units (-->4GlcAbeta1-->3GalNAc(4,6-O-sulfate)beta1-->). Binding studies revealed that the interaction of chondroitin sulfate with PF-4 required at least 20 monosaccharide units for significant binding. The di-O-sulfated disaccharide units in neutrophil glycosaminoglycans clearly promoted the affinity to PF-4, which showed a Kd approximately 0.8 microM, as the affinities of bovine cartilage chondroitin sulfate A, porcine skin dermatan sulfate, or bovine cartilage chondroitin sulfate C, all consisting exclusively of monosulfated disaccharide units, were found to be 3-5-fold lower. Taken together, our data indicate that chondroitin sulfate chains function as physiologically relevant binding sites for PF-4 on neutrophils and that the affinity of these chains for PF-4 is controlled by their degree of sulfation.  (+info)

Structural features and anticoagulant activities of a novel natural low molecular weight heparin from the shrimp Penaeus brasiliensis. (2/1431)

A natural low molecular weight heparin (8.5 kDa), with an anticoagulant activity of 95 IU/mg by the USP assay, was isolated from the shrimp Penaeus brasiliensis. The crustacean heparin was susceptible to both heparinase and heparitinase II from Flavobacterium heparinum forming tri- and di-sulfated disaccharides as the mammalian heparins. (13)C and (1)H NMR spectroscopy revealed that the shrimp heparin was enriched in both glucuronic and non-sulfated iduronic acid residues. The in vitro anticlotting activities in different steps of the coagulation cascade have shown that its anticoagulant action is mainly exerted through the inhibition of factor Xa and heparin cofactor II-mediated inhibition of thrombin. The shrimp heparin has also a potent in vivo antithrombotic activity comparable to the mammalian low molecular weight heparins.  (+info)

Stereochemical course and steady state mechanism of the reaction catalyzed by the GDP-fucose synthetase from Escherichia coli. (3/1431)

Recently the genes encoding the human and Escherichia coli GDP-mannose dehydratase and GDP-fucose synthetase (GFS) protein have been cloned and it has been shown that these two proteins alone are sufficient to convert GDP mannose to GDP fucose in vitro. GDP-fucose synthetase from E. coli is a novel dual function enzyme in that it catalyzes epimerizations and a reduction reaction at the same active site. This aspect separates fucose biosynthesis from that of other deoxy and dideoxy sugars in which the epimerase and reductase activities are present on separate enzymes encoded by separate genes. By NMR spectroscopy we have shown that GFS catalyzes the stereospecific hydride transfer of the ProS hydrogen from NADPH to carbon 4 of the mannose sugar. This is consistent with the stereospecificity observed for other members of the short chain dehydrogenase reductase family of enzymes of which GFS is a member. Additionally the enzyme is able to catalyze the epimerization reaction in the absence of NADP or NADPH. The kinetic mechanism of GFS as determined by product inhibition and fluorescence binding studies is consistent with a random mechanism. The dissociation constants determined from fluorescence studies indicate that the enzyme displays a 40-fold stronger affinity for the substrate NADPH as compared with the product NADP and utilizes NADPH preferentially as compared with NADH. This study on GFS, a unique member of the short chain dehydrogenase reductase family, coupled with that of its recently published crystal structure should aid in the development of antimicrobial or anti-inflammatory compounds that act by blocking selectin-mediated cell adhesion.  (+info)

Sensitive assay for mitochondrial DNA polymerase gamma. (4/1431)

BACKGROUND: The mitochondrial DNA polymerase gamma is the principal polymerase required for mitochondrial DNA replication. Primary or secondary deficiencies in the activity of DNA polymerase gamma may lead to mitochondrial DNA depletion. We describe a sensitive and robust clinical assay for this enzyme. METHODS: The assay was performed on mitochondria isolated from skeletal muscle biopsies. High-molecular weight polynucleotide reaction products were captured on ion-exchange paper, examined qualitatively by autoradiography, and quantified by scintillation counting. RESULTS: Kinetic analysis of DNA polymerase gamma by this method showed a K(m) for dTTP of 1.43 micromol/L and a K(i) for azidothymidine triphosphate of 0.861 micromol/L. The assay was linear from 0.1 to 2 microgram of mitochondrial protein. The detection limit was 30 units (30 fmol dTMP incorporated in 30 min). The linear dynamic range was three orders of magnitude; 30-30 000 units. Imprecision (CV) was 6.4% within day and 12% between days. Application of this assay to a mixed population of 38 patients referred for evaluation of mitochondrial disease revealed a distribution with a range of 0-2506 U/microgram, reflecting extensive biologic variation among patients with neuromuscular disease. CONCLUSION: This assay provides a useful adjunct to current laboratory methods for the evaluation of patients with suspected mitochondrial DNA depletion syndromes.  (+info)

Localization of the IgG effector site for monocyte receptors. (5/1431)

A peptide consisting of 10 amino acids derived from the CH3 region of human IgG was shown to bind to monocytes and to inhibit rosette formation of antibody-coated erythrocytes with human monocytes. Two myeloma proteins of the IgG1 and IgG3 subclass, both with known deletions in the CH2 region of the gamma chain, showed unimpaired ability to bind to monocytes. These experiments suggest that the isolated peptide represents the primary site of attachment of IgG to monocytes.  (+info)

In yeast the export of small glycopeptides from the endoplasmic reticulum into the cytosol is not affected by the structure of their oligosaccharide chains. (6/1431)

A "quality control" system associated with the endoplasmic reticulum (ER) that discriminates between misfolded proteins and correctly folded proteins is present in a variety of eukaryotic cells, including yeast. Recently, it has been shown that misfolded proteins that are N -glycosylated in the lumen of the ER are transported out of the ER, de-N-glycosylated by a soluble peptide: N -glycanase (PNGase) and degraded by action of the proteasome. It also has been shown that small N -glycosylatable peptides follow a fate similar to that of misfolded proteins, i.e., glycosylation in the lumen of the ER, transport out of the ER, and de- N -glycosylation in the cytosol. These processes of retrograde glycopeptide transport and de- N -glycosylation have been observed in mammalian cells, as well as in yeast cells. However, little is known about the mechanism involved in the movement of glycopeptides from the ER to the cytosol. Here we report a simple method for assaying N -glycosylation/de- N -glycosylation by simple paper chromatographic and electrophoretic techniques using an N -glycosylatable(3)H-labeled tripeptide as a substrate. With this method, we confirmed the cytosolic localization of the de- N -glycosylated peptide, which supports the idea that de- N -glycosylation occurs after the export of the glycopeptide from the lumen of the ER to the cytosol. Further, we found that the variations in the structure of the oligosaccharide chain on the glycopeptide did not cause differences in the export of the glycopeptide. This finding suggests that the mechanism for the export of small glycopeptides may differ from that of misfolded (glyco)proteins.  (+info)

Elaboration of pyrimidine-specific nucleosidases by human lymphoblastoid cells of established cultures. (7/1431)

Pyrimidine-specific nucleosidases were released rapidly by human lymphoblastoid cells of established cultures when incubated under certain culture conditions having no adverse affect on their viability or morphology. Nucleosidase production was not restricted to any particular type of lymphoblastoid line; enzymes with a high level of activity were elaborated by cells of cultures initiated from healthy subjects and patients with uncontrolled lymphocytic or myelocytic leukemia, as well as by cells of cultures exhibiting mostly B- or T-cell properties. Tritiated thymine and uracil, which were not incorporated to any appreciable extent by DNA- and RNA-synthesizing cells, were identified by paper chromatography as the primary products arising from nucleosidase degradation of radiolabeled thymidine, uridine, and cytidine. Neither adenosine nor guanosine was catabolized. These heat-labile and ultraviolet-sensitive enzymes with a molecular weight of 5 to 10 X 10(4) did not affect the viability, morphology, or proliferation of lymphocytes in mitogenactivated cultures, lymphoblastoid cells in long-term cultures, or fibroblasts in monolayer cultures.  (+info)

Covalent linkage of polyamines to peptidoglycan in Anaerovibrio lipolytica. (8/1431)

Spermidine and cadaverine were found to be constituents of the cell wall peptidoglycan of Anaerovibrio lipolytica, a strictly anaerobic bacterium. The peptidoglycan was degraded with the N-acetylmuramyl-L-alanine amidase and endopeptidase into two peptide fragments, peptide I and peptide II, at a molar ratio of 4:1. Peptides I and II were identified as L-alanine-D-glutamic acid(alphacadaverine)gammameso-diaminopimelic acid (DAP)-D-alanine and L-alanine-D-glutamic acid(alphaspermidine)gammameso-DAP-D-alanine, respectively. The N(1)-amino group of spermidine was linked to the alpha-carboxyl group of the D-glutamic acid residue of peptide II.  (+info)

Introduction. Identification of amino acids by using paper chromatography Aim To separation and identification of amino acids by using paper chromatography Introduction Chromatography is a techniques separation of mixtures It involves passing the sample, a mixture which contains the analyte, in the mobile phase, often in a stream of solvent, through the stationary phase. The stationary phase retards the passage of the components of the sample. When components pass through the system at different rates they become separated in time, like runners in a mass-start foot race. Each component has a characteristic time of passage through the system, called a retention time. Chromatographic separation is achieved when the retention time of the analyte differs from that of other components mixtures in the sample.

Matter makes up everything in the universe. Our body, the stars, computers, and coffee mugs are all made of matter. There are three different types of matter: solid, liquid, and gas. A solid is something that is normally hard (your bones, the floor under your feet, etc.), but it can also be powdery, like sugar or flour. Solids are substances that are rigid and have definite shapes. Liquids flow and assume the shape of their container; they are also difficult to compress (a powder can take the same shape as its container, but it is a collection of solids that are very small). Examples of liquids are milk, orange juice, water, and vegetable oil. Gases are around you all the time, but you may not be able to see them. The air we breathe is made up of a mixture of gases. The steam from boiling water is waters gaseous form. Gases can occupy all the parts of a container (they expand to fill their containers), and they are easily compressed.. Matter is often a mixture of different substances. A ...

Heroin at a concentration which inhibits the transport of lysine into Staphylococcus aureus stimulates the incorporation of glycerol into the phospholipid fraction of the cells. The stimulation is accompanied by an increased turnover of the major phospholipid, phosphatidylglycerol. Chromatographic examination of the lipid appears to show the presence of new phospholipids, judged from changes in the profile of elution from silicic acid columns and the appearance of new radioactive spots on silicic acid-impregnated paper chromatograms. Chromatographic analysis of the new components and their hydrolytic products shows that they contain phosphatidylglycerol and diphosphatidylglycerol. (N-Methyl-14C)-heroin is rapidly taken up by staphylococcal cells, but examination of that part of the radioactivity appearing in phospholipids shows that this is contained in glycerol residues. (7,8-3H)-Dihydroheroin is also taken up rapidly, and 3H is found in association with phospholipids; over 50% of this 3H ...
Prefixes are combined with base units and derived units to form multiples of SI units. The factors designated by prefixes are powers of 10, and most prefixes involve exponents that are simple multiples of 3, thereby facilitating conversion procedures using successive multiplications by 103 or 10−3. Compound prefixes formed by the combination of 2 or more SI prefixes generally are not used. It is preferable to use an expression with a single prefix. The kilogram is the only SI base unit with a prefix as part of its name and symbol (kg). However, because compound prefixes are not recommended, prefixes

In addition to these common reactions of amines and carboxylic acids, common alpha-amino acids, except proline, undergo a unique reaction with the triketohydrindene hydrate known as ninhydrin. Among the products of this unusual reaction (shown on the left below) is a purple colored imino derivative, which provides as a useful color test for these amino acids, most of which are colorless. A common application of the ninhydrin test is the visualization of amino acids in paper chromatography. As shown in the graphic on the right, samples of amino acids or mixtures thereof are applied along a line near the bottom of a rectangular sheet of paper (the baseline). The bottom edge of the paper is immersed in an aqueous buffer, and this liquid climbs slowly toward the top edge. As the solvent front passes the sample spots, the compounds in each sample are carried along at a rate which is characteristic of their functionality, size and interaction with the cellulose matrix of the paper.

Monday - We completed two labs on Monday. In the first, we separated the pigments found in a leaf of spinach using a technique called paper chromatography. Using an organic solvent, the four pigments in a spinach leaf travel different distances on a piece of paper so that the students can see that green is not the only color of the pigments in a plant. While that experiment was running (it takes awhile for the solvent to travel on the paper), the students looked at the structure of a leaf under the microscope. For homework, the students completed any of the lab questions that they did not complete in class ...
Sucralfate is an amorphous complex of aluminium hydroxide and sucrose sulphate, identified by the name: β-D-fructofuranosyl-α-D-glucopyranoside octakis (hydrogen sulphate) aluminium complex. When the pH in the stomach is below 4, there is extensive polymerization and cross-linking of Sucralfate. The condensed polymer is a very sticky, viscid, yellow white gel. Even though the pH in the duodenum is well above 4, gel retains its viscid, demulcent properties. The gel adheres strongly to epithelial cells and to the base of ulcer craters. The affinity for the crater base is much higher than that for the epithelial surface and it is difficult to wash the gel from the crater. The gel remains adherent to ulcerated epithelium for, at least 12 hours and this binding to ulcer craters probably represent the main therapeutic action ofSucralfate ...

We need to define how prefixes interact with contractions. I propose that mappings with prefixes have precedence, and that prefixes should be matched first. This is to keep them reasonably implementable: When we have a mapping with both a prefix and a contraction suffix (like in Japanese: ぐ,ゞ), then the matching needs to go in both directions. The contraction might involve discontiguous matching which needs complex text iteration and handling of skipped combining marks (or rewriting of the text, as in the UCA). Prefix matching should be first because it is contiguous and therefore simple. Once the prefix is matched, we can return to the original text index (right after the prefix) and look at all of the contractions for the prefix ...

Ark monitors collect data by sending scamper probes continuously to destination IP addresses. Destinations are selected randomly from each routed IPv4 /24 prefix on the Internet such that a random address in each prefix is probed approximately every 48 hours (one probing cycle). A single monitor wont probe all prefixes, but the prefixes it does probe will be randomly distributed, which gives a good sample cross section of the address space. As each probe travels from the monitor to its final destination, it passes through several IP addresses (ie, routers) which are owned by different autonomous systems (ASes ...

Concentrations of uranium as low as 1 ppm are determined in soils and sediments by ascending paper chromatography, subsequent to a hot nitric acid attack of the samples. The reagent 1-(2-pyridylazo)-2-napthol (PAN), which is used to develop the chromatograms, is capable of detecting 0.05 micrograms of uranium. The method is rapid and inexpensive. ...
Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase). In paper chromatography, a small amount of the mixture to be separated is placed close to the edge of a piece of paper. The edge of the paper is then immersed in a developing solution. As the developing solution ascends up the paper by capillary action, the. components of the sample are carried along at different rates. To prevent evaporation of the developing solution, this process is carried out in a closed container.. Notes:. Each component of the mixture will move a definite distance on the paper in proportion to the distance that the solvent moves. This ratio, H f = distance component moves/distance solution moves, can be calculated for each component to aid In identification. Hf values are dependent upon the paper, the developing solution, and the amount of ...
Prior to the 1970s, few reliable chromatographic methods were commercially available to the laboratory scientist. During 1970s, most chemical separations were carried out using a variety of techniques including open-column chromatography, paper chromatography, and thin-layer chromatography. However, these chromatographic techniques were inadequate for quantification of compounds and resolution between similar compounds. During this time, pressure liquid chromatography began to be used to decrease flowthrough time, thus reducing purification times of compounds being isolated by column chromatogaphy. However, flow rates were inconsistant, and the question of whether it was better to have constant flow rate or constant pressure was debated. (Analytical Chem. vol 62, no. 19, oct 1 1990 ...
1. A synthetic 3-([14C]valine)-labelled tetradecapeptide renin substrate was used to measure renin concentration. Renin liberated 14C-labelled angiotensin I, which was separated from the labelled substrate by paper chromatography. The conversion of substrate into angiotensin I was quantitated by liquid-scintillation counting of radioactivity. 2. The rate of conversion of the substrate into angiotensin I was shown to be linearly related to renin concentration and time under suitable conditions. Angiotensin generation measured in this system agrees well with that measured by bioassay. 3. It is suggested that the use of a pure substrate offers advantages that include the standardization of current units of renin measurement.. ...

This observation gives a very simple linear solution(because there are only 3 possible values of a prefix sum mod 3, we can simply find the first and the last one).. For example, if the input array is {1, 2, 3, -4, -1}, the prefix sums are {0, 1, 0, 0, 2, 1}. (there are n + 1 prefix sums because of an empty prefix). Now you can just take a look at the first and last occurrence of 0, 1 and 2.. ...
