The N-linked carbohydrate chains of recombinant human erythropoietin expressed in CHO cells were quantitatively released with peptide-N4-(N-acetyl-beta-glucosaminyl)asparagine amidase F, separated from the remaining O-glycoprotein by gel-permeation chromatography, and subsequently fractionated via FPLC on Mono Q, HPLC on Lichrosorb-NH2 and high-pH anion-exchange chromatography on CarboPac PA1. The purified sialylated oligosaccharides were ... read more analyzed by one-dimensional and two-dimensional 500-MHz 1H-NMR spectroscopy. When necessary, oligosaccharides were treated with endo-beta-galactosidase (and N-acetyl-beta-glucosaminidase) followed by 1H-NMR analysis of the incubation products, to obtain additional structural information. Di-, tri-, tri- and tetraantennary, N-acetyllactosamine-type oligosaccharides occur which can be completely (major) or partially (minor) sialylated. Three different types of alpha2-3-linked sialic acids are present, namely, N-acetylneuraminic acid (95%), ...

A NOVEL CORE STRUCTURE, LACKING HEPTOSE AND PHOSPHATE, OF THE LIPOPOLYSACCHARIDE FROM THE GRAM-NEGATIVE BACTERIUM PSEUDOMONS...
The extracted lipopolysaccharides (LPSs) fraction of the plant-pathogenic bacterium Pseudomonas cichorii contained two different molecules, the first of them an LPS possessing an O-specific polysaccharide made up of four 2-acetamido-2,6-dideoxy sugars linked linearly in a tetrasaccharide repeating unit. The structure of the second LPS component is reported here: it was of the rough form and contained a novel type of core region. The rough form LPS of Ps. cichorii was de-O-acylated by mild hydrazinolysis and then de-N-acylated with hot 4 M KOH. The oligosaccharide representing the complete carbohydrate backbone of the LPS was isolated by high-performance anion-exchange chromatography. Its structural characterization employed compositional and methylation analyses, matrix-assisted laser desorption/ionisation mass spectrometry and 1H, 13C and 31P NMR spectroscopy, with application of various 1D and 2D experiments. The carbohydrate backbone of this core region consisted of a hexasaccharide that ...

The oligosaccharide chains of microheterogeneous bovine pancreatic DNAases were characterized by the lectin-nitrocellulose sheet method. The active fractions of the DNAases from column chromatography showed four major and several minor spots on a two-dimensional polyacrylamide gel. They were transferred on to nitrocellulose sheets and treated with glycosidases (neuraminidase, endo-beta-N-acetyl glucosaminidase H or F, or peptide N-glycosidase F) and treated with peroxidase-coupled lectins (concanavalin A, Ricinus communis agglutinin or wheat-germ agglutinin). From the results, the most probable oligosaccharide types were proposed to be as follows: the four major spots contained components which had high-mannose type or hybrid-type oligosaccharides, such as those susceptible to endo-beta-N-acetylglucosaminidase H. In addition, spot 1 contained a complex-type biantennary oligosaccharide without sialic acid and spot 3 contained a tri- or tetra-antennary complex-type oligosaccharide with sialic ...
Structural glycobiology of antibody recognition in xenotransplantation and cancer immunotherapy
Carbohydrate antigens recognized by natural or preformed and elicited antibodies are central to transplantation/transfusion rejection across ABO blood group and species (xenotransplantation) barriers and are also promising candidates for cancer immunotherapy (Ramsland 2005). The key carbohydrate determinants (epitopes) recognized by antibodies are synthesized by a series of intracellular glycosyltransferases and are expressed on the surface of cells as glycolipids and glycoproteins. Often the minimal carbohydrate epitopes are located at the terminal end of more complex oligosaccharide chains, which result in these epitopes being displayed at a wide range of surface densities and contexts (e.g., glycolipids or glycoproteins). For example, many tumor-associated carbohydrate antigens are broadly expressed at very high densities on the cell surface of primary and metastatic tumors, but the same carbohydrates occur at much lower levels and are typically restricted to a few cell types in healthy ...
Enzymlc methods of carbohydrate analysis - Amino Acids
There are a large number of enzymes that are capable of modifying carbohydrates or carbohydrate derivatives, and that may be used in various analytical methods. The hydrolytic enzymes, which break glycosidic linkages, are useful in the study of disaccharide or polysaccharide structure and in methods for quantitation (Table 9.2). Such enzymes will hydrolyse the glycosidic linkages between the monosaccharide residues and release the individual components for further analysis. The enzyme is chosen bearing in mind the nature of the glycosidic linkage involved, which may not be unique to one particular disaccharide or polysaccharide. Thus a-glucosidase will hydrolyse both the a(l-»4) linkage of maltose and the a( 1-»2) linkage of sucrose, resulting in the release of glucose in both cases.. ...

Earths outer core poor in oxygen • Bioscholar News
Oxygen is the most abundant element in the planet, so it is not unreasonable to expect that it might be one of the dominant light elements in the core.. The composition of the Earths core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well.. Now, a new research from a team including Yingwei Fei from Carnegies Geophysical Laboratory has revealed that oxygen does not have a major presence in the outer core.. This has major implications for our understanding of the period when the Earth formed through the accretion of dust and clumps of matter.. According to current models, in addition to large amounts of iron, the Earths liquid outer core contains small amounts of so-called light elements, possibly sulfur, oxygen, silicon, carbon, or hydrogen.. The team provides new experimental data that narrow down the identity of the light elements present in Earths outer core.. High-speed ...

15 new trams for Nottingham delivered - but extension delayed
The phase two expansion of Nottinghams tram system is not likely to open until early next year, rather than the end of this year as hoped, because of delays duering construction.. The contractors, a JV of Taylor Woodrow and Alstom, said most of the major construction works on Nottingham Express Transit phase two will be finished by the end of this summer, with the major structures virtually complete already, as is the utility diversion scheme.. It says that 25km of track has been laid along the two routes, with OLE installation well underway, and 15 of the 22 new trams have been delivered.. Paul Harris, programme director, said: There has been speculation recently that construction works might be unduly delayed until next year. Yes, the project has presented some challenges, but we are on target to substantially complete all key infrastructure works over the next two to three months and we are working towards handing the new lines over for passenger services in the first part of 2015.

Fatty Acid and Polar Lipid Composition of the Genus Amycolatopsis: Application of Fast Atom Bombardment-Mass Spectrometry to...
Phospholipid patterns of 15 representative strains of the genus Amycolatopsis were recorded by two-dimensional thin-layer chromatography. The structure analysis of the isolated phospholipids was verified by fast atom bombardment-mass spectroscopy. The positive- and negative-ion spectra of the partially purified phospholipid fractions qualitatively reflect their distinctive composition. All strains contained diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylinositol. Two different types of phosphatidylethanolamine and phosphatidylmethylethanolamine were detected, viz., compounds with or without hydroxy fatty acids. These phospholipid patterns underline the integrity of the genus. Fast atom bombardment-mass spectrometry analysis of phospholipid patterns may serve as an aid for differentiation of bacterial species.

Equine lutropin and chorionic gonadotropin bear oligosaccharides terminating with SO4-4-GalNAc and Sia alpha 2,3Gal,...
Equine chorionic gonadotropin (eCG) and lutropin (eLH) are heterodimeric glycoprotein hormones which are synthesized in the placenta and pituitary, respectively. The beta subunits of eCG and eLH, like their alpha subunits, arise from a single gene and have identical amino acid sequences. In contrast, the beta subunits of CG and LH in primates arise from different genes and differ in sequence. We have examined the structures of the Asn-linked oligosaccharides on eCG and eLH. eCG bears di- and tri-branched Asn-linked oligosaccharides terminating with Sia alpha 2,3 or 6Gal beta 1,4GlcNAc. In contrast, , 72% of the Asn-linked oligosaccharides on eLH have 1 or 2 branches terminating with the sequence SO4-4-GalNAc beta 1,4GlcNAc. The nonsulfated oligosaccharides on eLH are neutral (6% of the total) or have branches terminating with sialic acid-Gal (22% of the total). Since the alpha and beta subunits of eCG and eLH both contain the tripeptide motif, Pro-Xaa-Arg/Lys, recognized by the glycoprotein ...

國立交通大學機構典藏:Synthetic heparin and heparan sulfate oligosaccharides and their protein interactions
Heparin and heparan sulfate bind a host of basic proteins that take advantage of the sugars dense structural information. The significance of these interactions in various aspects of development, physiology, and disease stimulated keen interest in evaluating structure-activity relationships. The well-defined heparin and heparan sulfate oligosaccharides needed for these studies can be mainly accessed by chemical synthesis and, more recently by chemoenzymatic means. The various synthetic strategies available to chemical synthesis have recently enabled the acquisition of several regular and irregular sequences, including a number of dodecasaccharides, through improved coupling methods and judicial protecting group manipulations. Controlled chain elongation and critical application of modification enzymes allowed the generation of well-defined constructs via chemoenzymatie synthesis. Investigations of various protein interactions with the synthetic constructs delivered valuable informatio

We have analyzed the O-antigen polysaccharide of the previously uncharacterized Escherichia coli strain TD2158 which is a host of bacteriophage HK620. This bacteriophage recognizes and cleaves the polysaccharide with its tailspike protein (TSP). The polysaccharide preparation as well as oligosaccharides obtained from HK620TSP endoglycosidase digests were analyzed with NMR spectroscopy. Additionally, sugar analysis was performed on the O-antigen polysaccharide and MALDI-TOF MS was used in oligosaccharide analysis.

Oligosaccharide Analysis via Anion Attachment Using Negative Mode Elec by Yanjie Jiang
Eleven tested anions were able to form adducts with neutral oligosaccharides at low cone voltage in negative ion mode electrospray mass spectrometry. Among them, fluoride and acetate have the abilities to significantly enhance the absolute abundance of [M-H]- for neutral oliogosaccharides. The chloride adduct has the best stability among all the adduct species investigated. For the above three anions, CID of adduct species may be used for structural determination of neutral oligosaccharides. In the presence of F- and Ac-, simultaneous detection of acidic oligosaccharides and neutral oligosaccharides was achieved. The ratio of Cl- : non-Cl-containing product ions obtained in CID spectra of chloride adducts of disaccharides was used to differentiate anomeric configurations of disaccharides. Density functional theory (DFT) was employed to evaluate the optimized structures of chloride adducts of disaccharides. The formation and decomposition of chloride adducts with oligosaccharides of different

JCI - Antibodies targeting sialyl Lewis A mediate tumor clearance through distinct effector pathways
Sialyl Lewis A (sLeA, also known as CA19-9), a tetrasaccharide selectively and highly expressed on advanced adenocarcinomas including colon, stomach, and pancreatic cancers, has long been considered as an attractive target for active and passive vaccination. While progress in antibodies targeting tumor-associated protein antigens resulted in an impressive array of therapeutics for cancer treatment, similar progress in exploiting tumor-associated carbohydrate antigens, such as sLeA, has been hampered by the lack of a detailed understanding of the singular characteristics of these antigens. We have addressed this issue by analyzing antibodies derived from patients immunized with an sLeA/KLH vaccine. These antibodies were engineered to mediate tumor clearance in vivo in preclinical models through Fc-FcγR interactions. However, in contrast to protein antigens in which hFcγRIIIA engagement was both necessary and sufficient to mediate tumor clearance in both preclinical and clinical settings, a ...
Carbohydrate sulfotransferase 5
Sulfotransferase that utilizes 3-phospho-5-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the transfer of sulfate to position 6 of non-reducing N-acetylglucosamine (GlcNAc) residues and O-linked sugars of mucin-type acceptors. Acts on the non-reducing terminal GlcNAc of short carbohydrate substrates. However, it does not transfer sulfate to longer carbohydrate substrates that have poly-N-acetyllactosamine structures. Has no activity toward keratan. Not involved in generating HEV-expressed ligands for SELL. Its substrate specificity may be influenced by its subcellular location ...

Glycomics Technology Platform at Creative Proteomics | Market News Latest
In the few years since the beginning of glycomics in 21th century, many achievements have been made in the study of glycomics, especially in the discovery of sugar genes and the elucidation of the new structure of sugar chain. Although glycomics research has made remarkable achievements in these fields, there are many unknown intermediate links between sugar genes and sugar chains, sugar chains and glycan binding proteins, and there is a general lack of detailed research on the relationship between structure and function.. These fields are not only related to the progress of glycomics itself, but also directly related to the progress of proteome planning, so it has become a major bottleneck in the development of life science.. The advancement of analytical techniques has always been a direct driving force in the development of glycomics. It is the rapid development and wide application of modern instrument analysis technology that lead to the overall prosperity of glycomics research, and inject ...
Fujirebio Products - CanAg CA15-3 EIA
The MUC-1 antigen is a membrane-anchored mucin-type glycoprotein present in malignant and normal epithelial cells of certain organs, e.g. breast, lung, ovary, pancreas and colon (1). The apoprotein of the MUC-1 mucin contains a transmembrane domain, a cytoplasmic domain, and an extracellular carbohydrate rich domain. The extracellular domain is characterized by polymorphism with respect to the number of a 20 amino acid tandem repeat (VNTR polymorphism). The CanAg CA15-3 EIA is based on two mouse monoclonal antibodies, Ma695 as catcher antibody recognizing a sialylated carbohydrate epitope expressed on the MUC-1 antigen and Ma552 as tracer antibody targeting the PDTRPAPG region of the protein core (2-5).The MUC-1 breast cancer mucin (CA15-3 antigen) is secreted from tumor cells and is a well-established serological marker for monitoring the clinical course of breast cancer patients (6). ...

RNase B is a glycoprotein which possesses an amino acid composition indistinguishable from that of RNase A and which contains carbohydrate to the extent of 6 residues of mannose and 2 residues of N-acetylglucosamine per molecule. It is consequently considered to be a carbohydrate derivative of RNase A. ( Tarentino, A., Plummer, J., and Maley, F.: Studies on the Oligosaccharide Sequence of Ribonuclease B, J. Biol. Chem., 245, 4150 (1970 ...

The present study tested and confirmed the hypothesis that autoantibodies to aberrant O-glycopeptide epitopes represent a fruitful source of sensitive biomarkers for early detection of cancer. Cancer-associated IgG autoantibodies to several O-glycopeptide epitopes were identified in MUC1, whereas IgG antibodies to peptide epitopes were not detected. The study therefore clearly supports that autoantibody biomarker discovery strategies should include aberrant posttranslational modifications for greatest success. Chemoenzymatic synthesis of cancer-associated O-glycopeptides in combination with a microarray platform was shown to be a feasible strategy for broader analysis of the entire cancer O-glycopeptidome.. Initially, we found an absence of immature nonsialylated MUC1 and MUC16 glycoforms in serum of cancer patients with elevated mucin levels, suggesting that these glycoforms are removed by immune cells or scavenger receptors recognizing immature uncapped glycans. This is in agreement with Varki ...

An estimate of the relative abundance of the various O-glycans was determined from nanoLC-ESI-IT-MS analysis of trypsin-generated (glyco)peptides. It should be noted that because the signal of the monosialylated O-glycopeptide in triply charged state overlapped with the doubly charged peak of the hinge repeat peptide with a putative acetylation modification in all samples, only the doubly charged signal of the monosialylated O-glycopeptide was quantified, thereby leading to an underestimation of this O-glycoform. Furthermore, it is known that glycopeptides with different glycan structures can have different response factors (35), and thus the relative abundances we measured may not accurately reflect the real ratios. In order to obtain a more reliable estimate of the percentage of the hinge repeat motif bearing an O-glycan, tryptic IgG peptides were incubated with exoglycosidases, trimming all O-glycans down to a single N-acetylhexosamine. A previous study of quantitative measurements of a ...
