Abstract
The biological recognition of complex-type N-glycans is part of many key physiological and pathological events. Despite their importance, the structural characterization of these events remains unsolved. The inherent flexibility of N-glycans hampers crystallization and the chemical equivalence of individual branches precludes their NMR characterization. By using a chemoenzymatically synthesized tetra-antennary N-glycan conjugated to a lanthanide binding tag, the NMR signals under paramagnetic conditions discriminated all four N-acetyl lactosamine antennae with unprecedented resolution. The NMR data revealed the conformation of the N-glycan and permitted for the first time the direct identification of individual branches involved in the recognition by two N-acetyllactosamine-binding lectins, Datura stramonium seed lectin (DSL) and Ricinus Communis agglutinin (RCA120).

Abstract
N-linked oligosaccharides often act as ligands for receptor proteins in a variety of cell recognition processes. Knowledge of the solution conformations, as well as protein-bound conformations, of these oligosaccharides is required to understand these important interactions. In this paper we present a model for the solution conformations sampled by a simple trimannoside, methyl 3, 6-di-O-(alpha-D-mannopyranosyl)-alpha-D-mannopyranoside, which contains two of the most commonly found glycosidic linkages in N-linked oligosaccharides. This model was derived from simulated annealing protocols incorporating distance restraints extracted from NOESY spectra along with torsional restraints computed from three-bond (1)H-(13)C coupling constants measured across the glycosidic bonds. The model was refined in light of unrestrained molecular dynamics simulations conducted in the presence of solvent water. The resulting model depicts a molecule undergoing conformational averaging in solution, adopting four major and two minor conformations. The four major conformations arise from a pair of two-state transitions, one each at the alpha(1-->3) and alpha(1-->6) linkages, whereas the minor conformations result from an additional transition of the alpha(1-->6) linkage. Our data also suggest that the alpha(1-->3) transition is fast and changes the molecular shape slightly, whereas the alpha(1-->6) is much slower and alters the molecular shape dramatically.

Abstract
Glycopeptides of desired structure can be conveniently prepared by the coupling of reducing oligosaccharides to aspartic acid of peptides via their glycosylamines formed in the presence of saturated aqueous ammonium hydrogen carbonate. The resulting oligosaccharide chains are N-linked to asparagine as in natural glycoproteins, allowing different peptide oligosaccharide combinations to be analysed for conformational effects. In the present paper, a pentapeptide of ovalbumin was coupled to Man5GlcNAc2 oligosaccharide and the glycopeptide and the two parent compounds compared by NMR ROESY experiments and molecular dynamics simulations. Despite the small size of the peptide, conformational effects were observed suggestive of the oligosaccharide stabilising the peptide in solution and of the peptide influencing oligosaccharide conformation. These effects are relevant to the function of glycosylation and the enzymic processing of oligosaccharide chains.

Abstract
Recent advances in the conformational analysis of oligosaccharides have focused on protein-bound oligosaccharides, glycopeptides, and glycoproteins, as well as on the conformational dynamics about glycosidic linkages. Significant progress has been made possible by dramatic improvements in NMR techniques and advances in computational chemistry and technology. Transferred nuclear Overhauser effects have been used to infer the conformations of carbohydrate ligands bound to protein receptors such as antibodies, lectins and enzymes. The increased use of combined NMR spectroscopic and computational protocols has resulted in insights into the dynamics of glycan chains.

Abstract
This study represents the first detailed investigation of the nature of highly sulfated (keratan-sulfate-like) complex-type asparagine-linked glycans having a tetraantennary core structure and shows the effectiveness of fast-atom-bombardment mass spectrometric (FAB-MS) methods incorporating derivatization and mild methanolysis for analyzing such complex types of sulfated glycans. The structure of the N-glycan chains was unambiguously established by a combination of compositional analysis, methylation analysis, mild methanolysis for desulfation, hydrazinolysis/nitrous acid deamination, enzymatic (endo-beta-galactosidase and peptide:N-glycosidase F) digestions, and instrumental analyses (1H-NMR spectroscopy and FAB-MS) which revealed the novel repeating sulfated carbohydrate sequences, +/- Gal beta 1-->4Gal beta 1[-->(HSO3-->6)GlcNAc beta 1-->3(+/- Gal beta 1-->4)Gal beta 1]n--> (see Structure I; p + q + r + s approximately 14). This sequence is unique in: (a) the skeletal structure is similar to that of keratan sulfate but is completely devoid of 6-O-sulfated Gal residues and (b) the presence of branched Gal residues in the sequence -->4GlcNAc beta 1-->3(Gal beta 1-->4)Gal beta 1-->.
