Characterization and partial purification of a novel neutrophil membrane-associated kinase capable of phosphorylating the respiratory burst component p47phox. (1/6642)

The phosphorylation of p47phox is widely viewed as an important step in the activation of the neutrophil respiratory burst oxidase system. The exact nature of the kinase(s) responsible remains to be elucidated. We show here that such a kinase was detected on neutrophil membranes activated by either PMA or formyl-methionyl-leucyl-phenylalanine. This enzyme is not intrinsic to the neutrophil membrane and could be eluted with 0.5 M NaCl. The kinase activity was partially purified and was found not to be due to the presence of previously suggested kinases, including protein kinase C isotypes, mitogen-activated protein kinase and protein kinase B. Gel filtration and renaturation in substrate gels suggest a molecular mass of between 45 and 51 kDa. The kinase activity was independent of calcium and lipids but was potently inhibited by staurosporine. Treatment with protein phosphatase 2Ac suggested that the kinase was activated by serine/threonine phosphorylation. Phosphopeptide maps indicated that the kinase phosphorylated p47phox on similar sites to those found in vivo. These results indicate that activation of neutrophils by PMA results in the activation of a membrane-associated kinase that may play a part in the regulation of neutrophil NADPH oxidase through its ability to phosphorylate p47phox.  (+info)

Physical characterization of a low-charge glycoform of the MUC5B mucin comprising the gel-phase of an asthmatic respiratory mucous plug. (2/6642)

We have previously noted that sequential extraction of an asthmatic mucous exudate with 6 M guanidinium chloride yielded a fraction of the mucins that were most resistant to solubilization and of high Mr [Sheehan, Richardson, Fung, Howard and Thornton (1995) Am. J. Respir. Cell Mol. Biol. 13, 748-756]. Here we show that this mucin fraction is dominated (at least 96% of the total) by the low-charge glycoform of the MUC5B gene product. Seen in the electron microscope the mucins appeared mainly as compact 'island' structures composed of linear threads often emanating from globular 'nodes' rather than the discrete linear threads more typical of mucins that we have previously described. The effect of reducing agents was as expected for other gel-forming mucins, i.e. reduced subunits or monomers of Mr 3x10(6)) were produced within 15 min of treatment. Kinetic experiments on the cleavage of the intact mucins with the proteinase trypsin indicated two clear regimes of fragmentation. An initial rapid cleavage generated mucins ranging from Mr=4x10(6) to 30x10(6) that in the electron microscope appeared as polydisperse threads (500-3000 nm in length), similar to normal and other respiratory mucins that we have previously characterized. A subsequent slower fragmentation over many hours yielded a major fragment of Mr 3x10(6) and length 200-600 nm, very similar in size and Mr to the subunits obtained by reduction. The results suggest that the MUC5B mucin is assembled, first into polydisperse linear threads, which are then linked together via a protein-mediated process. This might involve part of the mucin polypeptide or an as yet unidentified protein(s). The high proteinase susceptibility of the linkage suggests that it might be a point of control for mucin size and thus mucus rheology.  (+info)

An improved method for the structural profiling of keratan sulfates: analysis of keratan sulfates from brain and ovarian tumors. (3/6642)

A previously developed method for the structural fingerprinting of keratan sulfates (Brown et al., Glycobiology, 5, 311-317, 1995) has been adapted for use with oligosaccharides fluorescently labeled with 2-aminobenzoic acid following keratanase II digestion. The oligosaccharides are separated by high-pH anion-exchange chromatography on a Dionex AS4A-SC column. This methodology permits quantitative analysis of labeled oligosaccharides which can be detected at the sub-nanogram ( approximately 100 fmol) level. Satisfactory calibration of this method can be achieved using commercial keratan sulfate standards. Keratan sulfates from porcine brain phosphocan and human ovarian tumors have been examined using this methodology, and their structural features are discussed.  (+info)

Purification and identification of a novel subunit of protein serine/threonine phosphatase 4. (4/6642)

The catalytic subunit of protein serine/threonine phosphatase 4 (PP4C) has greater than 65% amino acid identity to the catalytic subunit of protein phosphatase 2A (PP2AC). Despite this high homology, PP4 does not appear to associate with known PP2A regulatory subunits. As a first step toward characterization of PP4 holoenzymes and identification of putative PP4 regulatory subunits, PP4 was purified from bovine testis soluble extracts. PP4 existed in two complexes of approximately 270-300 and 400-450 kDa as determined by gel filtration chromatography. The smaller PP4 complex was purified by sequential phenyl-Sepharose, Source 15Q, DEAE2, and Superdex 200 gel filtration chromatographies. The final product contained two major proteins: the PP4 catalytic subunit plus a protein that migrated as a doublet of 120-125 kDa on SDS-polyacrylamide gel electrophoresis. The associated protein, termed PP4R1, and PP4C also bound to microcystin-Sepharose. Mass spectrometry analysis of the purified complex revealed two major peaks, at 35 (PP4C) and 105 kDa (PP4R1). Amino acid sequence information of several peptides derived from the 105 kDa protein was utilized to isolate a human cDNA clone. Analysis of the predicted amino acid sequence revealed 13 nonidentical repeats similar to repeats found in the A subunit of PP2A (PP2AA). The PP4R1 cDNA clone engineered with an N-terminal Myc tag was expressed in COS M6 cells and PP4C co-immunoprecipitated with Myc-tagged PP4R1. These data indicate that one form of PP4 is similar to the core complex of PP2A in that it consists of a catalytic subunit and a "PP2AA-like" structural subunit.  (+info)

Recombinant human peroxisomal targeting signal receptor PEX5. Structural basis for interaction of PEX5 with PEX14. (5/6642)

Import of matrix proteins into peroxisomes requires two targeting signal-specific import receptors, Pex5p and Pex7p, and their binding partners at the peroxisomal membrane, Pex13p and Pex14p. Several constructs of human PEX5 have been overexpressed and purified by affinity chromatography in order to determine functionally important interactions and provide initial structural information. Sizing chromatography and electron microscopy suggest that the two isoforms of the human PTS1 receptor, PEX5L and PEX5S, form homotetramers. Surface plasmon resonance analysis indicates that PEX5 binds to the N-terminal fragment of PEX14-(1-78) with a very high affinity in the low nanomolar range. Stable complexes between recombinant PEX14-(1-78) and both the full-length and truncated versions of PEX5 were formed in vitro. Analysis of these complexes revealed that PEX5 possesses multiple binding sites for PEX14, which appear to be distributed throughout its N-terminal half. Coincidentally, this part of the molecule is also responsible for oligomerization, whereas the C-terminal half with its seven tetratricopeptide repeats has been reported to bind PTS1-proteins. A pentapeptide motif that is reiterated seven times in PEX5 is proposed as a determinant for the interaction with PEX14.  (+info)

The proteins of the large subunit of rat liver ribosomes were separated into seven groups by stepwise elution from carboxymethylcellulose with LiCl at pH 6.5. Seventeen proteins (L4, L5, L7, L9, L11, L12, L13, L21, L22, L23, L26, L27, L30, L33, L35', L37, and L39) were isolated from three of the groups (B60, D60, G60) by ion exchange chromatography on carboxymethylcellulose and by filtration through Sephadex. The amount of protein obtained varied from 0.5 to 15 mg. Eight of the proteins (L9, L11, L13, L21, L22, L35', L37 and L39) had no detectable contamination; the impurities in the others were no greater than 9%. The molecular weight of the proteins was estimated by polyacrylamide gel electrophoresis in sodium dodecyl sulfate; the amino acid composition was determined.  (+info)

Acid-catalyzed lactonization of alpha2,8-linked oligo/polysialic acids studied by high performance anion-exchange chromatography. (7/6642)

Recent studies from many laboratories revealed remarkable structural, distributional, and functional diversities of oligo/polysialic acids (OSA/PSA) that exist in organisms ranging from bacteria to man. These diversities are further complicated by the fact that OSA/PSA spontaneously form lactones under even mildly acidic conditions. By using high performance anion-exchange chromatography (HPAEC) with nitrate eluents, we found that lactonization of alpha2,8-linked OSA/PSA (oligo/poly-Neu5Ac, oligo/poly-Neu5Gc and oligo/poly-KDN) proceeds readily, and the lactonization process displays three discrete stages. The initial stage is characterized by limited lactonization occurring between two internal sialic acid residues, reflected by a regular pattern of lactone peaks interdigitated with non-lactonized peaks on HPAEC. In the middle stage, multiple lactonized species are formed from a molecule with a given degree of polymerization (DP), in which the maximum number of lactone rings formed equals DP minus 2. At the final stage, completely lactonized species become the major components, resulting in drastic changes in the physicochemical properties of the sample. Interestingly, the smallest lactonizable OSA are tetramer, trimer, and dimer at the initial, middle, and final stages, respectively. At any of the stages, OSA/PSA of higher DP lactonize more rapidly, but all the lactone rings rapidly open up when exposed to mild alkali. Lactonized OSA/PSA are resistant to both enzyme- and acid-catalyzed glycosidic bond cleavage. The latter fact was utilized to obtain more high DP oligo/poly(alpha2,8-Neu5Gc) chains from a polysialoglycoprotein. Our results should be useful in preparation, storage, and analysis of OSA/PSA. Possible biological significance and bioengineering potentials of lactonization are discussed.  (+info)

Human triclonal anti-IgG gammopathy. I. Iso-electric focusing characteristics of the IgG, IgA and IgM anti-IgG and their heavy and light chains. (8/6642)

Human IgG, IgA and IgM anti-IgG autoantibodies have been isolated from the serum of an individual with Felty's syndrome. These were initially noted as soluble circulating serum complexes by analytical ultracentrifugation. Isolation was accomplished by solid phase immunoadsorption and each of the three antibody populations obtained was shown to be of restricted heterogeneity by liquid and polyacrylamide gel electrofocussing methods. Type kappa light chains were obtained from each protein. Co-isoelectric focusing experiments of all possible pairs of these light chains showed them to have identical net charge characteristics. Heavy chains obtained from each protein were also monoclonal and of differing isoelectric point. The availability of this serum provides a human model with which to study the changes which may occur in autoantibodies during the autoimmune response.  (+info)

A retention model is derived for inorganic cations eluted from cation-exchange columns with eluents containing a single competing cation and a complexing ligand. This model is evaluated using divalent solute cations and a low-capacity fixed-site cation-exchange column, and good agreement is obtained between theoretical and experimental results both for simple cation exchange and also when complexation effects are present. Sodium ions added to the eluent during pH adjustment were found to contribute significantly to the elution of solute cations and should be included in all calculations using the retention model. Retention characteristics were also studied for an ion-interaction chromatographic system using a C18 column, octanesulfonic acid as the ion-interaction reagent, and oxalate as the complexing ligand in the eluent. Experimental data for this system did not show close agreement with the ion-exchange retention model. Discrepancies are attributed to variations in the ion-exchange capacity ...

AU - Regnier, Fred E.. AU - Zhang, Xiang. PY - 2007/1/1. Y1 - 2007/1/1. N2 - Motivation: The still emerging combination of technologies that enable description and characterization of all expressed proteins in a biological system is known as proteomics. Although many separation and analysis technologies have been employed in proteomics, it remains a challenge to predict peptide behavior during separation processes. New informatics tools are needed to model the experimental analysis method that will allow scientists to predict peptide separation and assist with required data mining steps, such as protein identification. Results: We developed a software package to predict the separation of peptides in strong anion exchange (SAX) chromatography using artificial neural network based pattern classification ...

A commercially available 4.6 mm id×50 mm polymethacrylate-based monolithic strong anion exchange column (ProSwiftTM SAX-1S) designed for the separation of proteins has been successfully used to separate small inorganic anions in the presence of a seawater sample matrix. Using a hydroxide eluent with suppressed conductivity detection the ion exchange capacity of this column declined over time; however, using KCl as the eluent, the column performance was stable with a capacity of 530 {micro}equiv. for nitrate. The optimum conditions for the separation of iodate, bromate, nitrite, bromide and nitrate were assessed by constructing van Deemter plots using 1.00 and 0.100 M KCl. Efficiencies of up to 26 700 plates/m were recorded using 1.00 M KCl, at a flow rate of 0.20 mL/min but iodate was not baseline resolved from the void peak. By reducing the concentration of the eluent to 0.100 M, efficiencies of up to 39 900 plates/m could be obtained at 0.35 mL/min. By employing a linear gradient ranging from ...
Pyrogenic organic matter (PyOM), the incomplete combustion product of organic materials, is considered stable in soils and represents a potentially important terrestrial sink for atmospheric carbon dioxide. One well-established method of measuring PyOM in the environment is as benzene polycarboxylic acids (BPCAs), a compound-specific method, which allows both qualitative and quantitative estimation of PyOM. Until now, stable isotope measurement of PyOM carbon involved measurement of the trimethylsilyl (TMS) or methyl (Me) polycarboxylic acid derivatives by gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). However, BPCA derivatives can contain as much as 150% derivative carbon, necessitating post-analysis correction for the accurate measurement of δ13 C values, leading to increased measurement error. Here, we describe a method for δ13 C isotope ratio measurement and quantification of BPCAs from soil-derived PyOM, based on ion-exchange chromatography (IEC-IRMS). The ...

Hydrophobic Interaction Chromatography is a separation technique that uses the properties of hydrophobicity to separate proteins from one another. In this type of chromatography, hydrophobic groups such as phenyl, octyl, or butyl, are attached to the stationary column. Proteins that pass through the column that have hydrophobic amino acid side chains on their surfaces are able to interact with and bind to the hydrophobic groups on the column. HIC separations are often designed using the opposite conditions of those used in ion exchange chromatography. In this separation, a buffer with a high ionic strength, usually ammonium sulfate, is initially applied to the column. The salt in the buffer reduces the solvation of sample solutes thus as solvation decreases, hydrophobic regions that become exposed are adsorbed by the medium. ...

Isolated neutrophils from healthy donors were used for the isolation of four highly purified forms of myeloperoxidase as determined by spectral (A430/A280 ratio 0.80-0.87) and enzyme-activity measurements. Although the myeloperoxidases exhibited different elution profiles on cation-exchange chromatography, gel filtration indicated similar relative molecular masses. When these forms were assayed for peroxidase and peroxidase-oxidase activities with several substrates, they all exhibited virtually the same specific activities. These results suggest that possible functional differences between the enzymes may be related to differences in their sites of action rather than to differences in enzyme activity. Myeloperoxidase from a patient with chronic myeloid leukaemia also revealed a similar heterogeneity on cation-exchange chromatography. However, this myeloperoxidase contained in addition one form with a lower and one form with a higher relative molecular mass, as indicated by gel-filtration ...
The isolation method is optimized for cultures grown in LB media; other rich media may require increased volumes of Suspension-, Lysis-, and Neutralization Buffer, and an additional wash step. The isolation procedure is suitable for all plasmid sizes; lysates of larger constructs (up to 100 kb) should be cleared by filtration to avoid shearing.. The yield of plasmid DNA preparations is dependent on several parameters, e.g., quality of the bacterial culture growth, amount of used culture suspension for the preparation, plasmid type used etc. As a rule of thumb the typical yield of a high copy number plasmid is about 3 - 5 µg of DNA per ml of original bacterial culture (pUC, pTZ, pGEM in common host strains like XL-1 blue, HB101, JM 109). The typical yield of low copy number plasmids is about 0.2 - 1 µg of DNA per ml of original bacterial culture.. The Genopure kits are supplied with folded filters to eliminate the time-consuming centrifugation step after the alkaline lysis. In approximately 2 ...

In order for pharmaceuticals to be safe, they must be clean of pollutants. Carbon dioxide can be used to make the purification process more environmentally friendly, which may seem paradoxical since carbon dioxide is usually associated with a negative climate impact. However, if carbon dioxide is recovered from other existing processes and if the use of environmentally hazardous organic solvents is reduced, large gains can be made both economically and environmentally.
The charge on the protein affects its behavior in ion exchange chromatography. Proteins contain many ionizable groups on the side chains of their amino acids including their amino - and carboxyl - termini. These include basic groups on the side chains of lysine, arginine and histidine and acidic groups on the side chains or glutamate, aspartate, cysteine and tyrosine. The pH of the solution, the pK of the side chain and the side chains environment influence the charge on each side chain. The relationship between pH, pK and charge for individual amino acids can be described by the Henderson-Hasselbalch equation, which is described in detail elsewhere: In general terms, as the pH of a solution increases, deprotonation of the acidic and basic groups on proteins occur, so that carboxyl groups are converted to carboxylate anions (R-COOH to R-COO-) and ammonium groups are converted to amino groups (R-NH3+ to R-NH2). In proteins the isoelectric point (pI) is defined as the pH at which a protein has no ...
