Macoma birmanica agglutinin recognizes glycoside clusters of beta-GlcNAc/Glc and alpha-Man

Macoma birmanica agglutinin (MBA) that seems to play crucial roles in the innate immunity of marine bivalve, M. birmanica has been earlier defined as GlcNAc/Man specific. However, most complementary carbohydrate structures to its binding domain and ligand clustering in its recognition profile have not been established. In this study, the complete recognition profile of MBA was examined by enzyme-linked lectin-sorbent assay and inhibition assay. Among the monosaccharides tested, GlcNAc was more reactive followed by Man and Glc, others were non-reactive; revealing the importance of equatorial -NAc group at C-2, -OH group at C-4 and C-6, and pyranose conformation of hexose. Moreover, beta-glycosides of GlcNAc and Glc were more potent whereas for Man it was alpha-glycoside. MBA recognized both exposed and internal alpha-Man and beta-GlcNAc/Glc residues well with most linkages except (beta1-4). This binding pattern was further extended and confirmed by polyvalent glycoside clusters of GlcNAc(beta1-2)Man(alpha1-, which was a better inhibitor than Man(alpha1-2/3/6)Man(alpha1- or Man(alpha1-3/6)Man(beta1- present in well-defined naturally occurring glycoproteins. This broad range specificity explains the importance of MBA as an important pattern recognition molecule that provides more realistic picture of carbohydrate-based immune response triggering.

A convenient preparation of several N-linked glycoamino acid building blocks for efficient solid-phase synthesis of glycopeptides

A high yielding route for the preparation of several Boc- and Fmoc-protected N-linked glycopeptide monomers was presented. It was found that these building blocks can be used for the solid-phase synthesis of glycopeptides or glycopeptidomimetics. A number of short glycopeptides- collagen mimics was prepared to demonstrate this applicability. The protocol employed was expected to be suitable for the synthesis of any desired N-linked glycopeptide.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10343-06-3 is helpful to your research., 10343-06-3

Chitooligosaccharide Synthesis Using an Ionic Tag

An environmentally improved synthesis of the N-differentiated chitotetrasaccharide CO-IV-(NH2), a key intermediate for the preparation of lipochitooligosaccharides and the TMG-chitotriomycin, is reported based on a chromatography-free ionic-liquid tagging approach. The method involves the glycosylation of ionic-liquid-tagged acceptors with thioglucosamine donors leading to the stereoselective formation of beta-(1?4)-linked glucosamine-containing oligomers.

Chemical Modification of the N Termini of Unprotected Peptides for Semisynthesis of Modified Proteins by Utilizing a Hydrophilic Protecting Group

A simple and efficient strategy for the selective modification of the peptide N terminus with an unnatural amino acid is described. A peptide having a SUMO-HisTag-TEV sequence (SUMO: small ubiquitin-related modifier, TEV: tobacco etch virus) preceding the N terminus of the target peptide was designed. Recombinant expression in E. coli and subsequent SUMO protease cleavage yielded the HisTag-TEV-target peptide. Partial protection of the lysine side chains of this peptide with d-glucopyranosyloxycarbonyl and removal of the HisTag-TEV sequence by TEV protease yielded the partially protected peptide with a free N-terminal amine. Coupling of selenocysteine selectively at the N terminus and subsequent acidic deprotection of the carbohydrate protecting groups yielded a modified peptide that can be used for native chemical ligation (NCL). As a proof of concept, the modification of a longer recombinant peptide with selenocysteinylserine (GalNAc) at the N terminus was demonstrated.

Carbohydrate coatings via aryldiazonium chemistry for surface biomimicry

Carbohydrates are extremely important biomolecules and their immobilization onto solid surfaces is of interest for the development of new biomimetic materials and of new methods for understanding processes in glycobiology. We have developed an efficient surface modification methodology for the functionalization of a range of materials with biologically active carbohydrates based on aryldiazonium chemistry. We describe the synthesis and characterization of carbohydrate reagents, which were subsequently employed for the one-step, solution-based modification of carbon, metals, and alloys with monosaccharides. We used a combination of spectroscopic and nanogravimetric methods to characterize the structure of the carbohydrate layers; we report an average surface coverage of 7.8 ¡Á 10-10 mol cm-2 under our experimental conditions. Concanavalin A, a mannose-binding lectin, and Peanut Agglutinin, a galactose-binding lectin, were found to bind from solution to their respective monosaccharide binding partners immobilized at the surface. This result suggests that the spontaneous chemisorption of aryldiazonium monosaccharide precursors leads to the formation of monosaccharide layers that retain the biological recognition specificity of the parent carbohydrate molecule. Finally, we carried out measurements using fluorescently labeled Bovine Serum Albumin (BSA) and found that these carbohydrate coatings reduce unspecific adsorption of this protein at carbon surfaces. These results suggest that aryldiazonium-derived carbohydrate coatings may offer a promising strategy for preventing undesirable protein accumulation onto surfaces.
