Sialyl Lewis x and derivatives have been synthesized using 0-1,4-galactosyltransferase and recombinant alpha-2,3-sialyltransferase and alpha-l,3-fucosyltransferase. The enzymatic glycosylations have been achieved on preparative scales with in situ regeneration of UDP-galactose, CMP-N-acetylneuraminic acid, and GDP-fucose. Additionally, galactosyltransferase and fucosyltransferases have been studied with respect to their substrate specificity and inhibition. The enzymatic procedures have also been used in the synthesis of 2?-deoxy-LacNAc, 2?-amino-2?-deoxy-LacNAc, 2-azido-Lac, Lewis x, the Lewis x analog with GlcNAc replaced with 5-thioglucose, [Gal-l-13C]-LacNAc, [Gal-1-13C]-sialyl Lewis x, and the corresponding terminal glycal. The synthesized 13C-labeled sialyl Lewis x and intermediates (including Lewis x and sialyl LacNAc) were used for conformational study using NMR techniques combined with calculations based on GESA and MM2 programs. GESA calculation of sialyl Lewis x gave four minimum-energy conformers, and the two (A and B) consistent with NMR results were further refined with MM2 calculation. The one (A’) with lower energy was picked as the preferred conformer which had all internuclear distances and glycosidic torsional angles consistent with the NMR analysis. The glycosidic torsional angle psi of Gal-GlcNAc, for example, was determined to be 18 on the basis of the coupling between Gal-1-13C and GlcNAc, while the predicted value was 15. The tetrasaccharide appears to form a well-defined hydrophilic surface along NeuAc-Gal- Fuc, and a hydrophobic face underneath NeuAc-Gal-GlcNAc. Comparing the conformation of sialyl Lewis x to sialyl Lewis a indicates that the recognition domain of sialyl Lewis x mainly comes from the sialic acid – galactose – fucose residues.

A novel lectin was purified to homogeneity from winter buds of Lysichiton camtschatcensis (L.) Schott of the Araceae family. It was a tetramer composed of two non-covalently associated polypeptides with small subunits (11 kDa) and large subunits (12 kDa). Sequencing of both subunits yielded unique N-terminal sequences. A cDNA encoding the lectin was cloned. The isolated cDNA contained an open reading frame that encoded 267 amino acids. It encoded both subunits, indicating that the lectin is synthesized as a single precursor protein that is post-translationally processed into two different subunits with 45% sequence identity. Each subunit contained a mannose-binding motif known to be conserved in monocot mannose-binding lectins, but its activity was not inhibited by monosaccharides, including methyl alpha-mannoside. Asialofetuin and yeast invertase were potent inhibitors. Lectin activity was detected in the buds formed during the winter season but not in the expanded leaves.

The Escherichia coli polyphosphate kinase (PPK) has been known to catalyze the reversible transfer of phosphate molecules between ATP and polyphosphate (poly(P)). It has also been found that the PPK catalyzes the kination of not only ADP but also other nucleoside diphosphates (NDPs) using poly(P) as a phosphate donor, yielding nucleotide triphosphates (NTPs). We used the PPK and poly(P) in place of pyruvate kinase and phosphoenol pyruvate for NTP regeneration followed by synthesis of sugar nucleotides in a cyclic synthesis system for oligosaccharides. It was confirmed that the PPK efficiently catalyzed the UTP regeneration in the cyclic system of N-acetyllactosamine synthesis. This novel activity of PPK enables us to perform the practical synthesis of oligosaccharides.

The golden wonder: Various alpha-amino acids such as glucosaminic acid, galactosaminic acid, or N-acetyl-glucosaminic acid can be obtained from the corresponding glucosamine derivatives (amino sugars). This is achieved through an aqueous oxidation that catalyzed by Au nanoparticles dispersed on basic support under mild reaction conditions in water. Copyright

C-glycosides are important compounds as they are used as bioactive molecules and building blocks. We have developed methods to concisely synthesize C-glycosides from unprotected 2-N-acyl-aldohexoses and unactivated ketones; we designed aldol-condensation-oxa-Michael addition reactions catalyzed by amine-based catalysts using additives. Depending on the conditions used, C-glycosides were stereoselectively obtained. Our methods allowed the C-C bond formations at the anomeric centers of unprotected carbohydrates under mild conditions to lead the C-glycosides in atom- and step-economical ways.

(Figure Presented) An acyclic receptor 1, containing phenanthroline- and aminopyridine-based recognition sites, has been established as a powerful carbohydrate receptor. Compared to the previously described acyclic receptors, compound 1 shows significantly higher binding affinities as well as selectivities, which are quite different from those of the earlier systems. The phenanthroline unit has been established as a valuable building block for the construction of effective and selective carbohydrate receptors.

Bacterial non-specific acid phosphatases normally catalyze the dephosphorylation of a variety of substrates. As shown previously the enzymes from Shigella flexneri and Salmonella enterica are also able to catalyze the phosphorylation of inosine to inosine monophosphate and D-glucose to D-glucose 6-phosphate (D-G6P) using cheap pyrophosphate as the phosphate donor. After optimization high yields (95%) are achieved in the latter reaction and we show here that it is possible to use these enzymes in a preparative manner. This prompted us to investigate by using 31P NMR and HPLC also the phosphorylation of a broad range of carbohydrates and alcohols. Many cyclic carbohydrates are phosphorylated in a regioselective manner. Non-cyclic carbohydrates are phosphorylated as well. Phosphorylation of linear alcohols, cyclic and aromatic alcohols is also possible. In all cases the acid phosphatase from Shigella prefers a primary alcohol function above a secondary one. We conclude that these enzymes are an attractive alternative to existing chemical and enzymatic methods in the phosphorylation of a broad range of compounds.

beta-Galactosidase activities from the recombinant thermophilic CLONEZYME(TM) glycosidase library were screened at 70C for catalysis of a transgalactosylation from o-nitrophenyl-beta-galactopyranoside to N-acetylglucosamine. Three thermophilic glycosidases (Gly001-06, -07 and -09) were found to produce predominantly the beta(1-4)-linked isomer, Gal beta(1-4)GlcNAc with up to 61% yield and less than 10% of the hydrolysis side reaction product. Thus, commercial recombinant thermophilic enzyme libraries constitute a novel class of biocatalysts for preparative organic synthesis.
