UDP-N-acetylmuramic acid (UDP-MurNAc) is a substrate of MurC, an important enzyme in the intracellular pathway of bacterial peptidoglycan biosynthesis. Various approaches towards preparation of UDP-Mur/VAc have been published but these synthetic preparations were shown to include many problematic steps. An optimization study with the focus on muramyl phosphate and UMP-morpholidate coupling was performed, resulting in a synthetic procedure enabling robust and easily reproducible production on a multi-gram scale.

A method is presented for the isolation of a lectin from a Japanese cultivar of Phaseolus vulgaris seed by an affinity chromatography on the heat-denaturated porcine thyroglobulin-Sepharose.The lectin is a glycoprotein whose molecular weight is 120,000; it consists of four apparently identical subunits, held together by non-covalent forces.The isoelectric point is 5.5 and the sedimentation constant is 6.66 S at pH 5.3.The lectin is nonspecific in agglutination for any types of human erythrocytes.The lectin induces mitosis in human lymphocytes at concentration between 10 and 100 mug per 3E6 lymphocytes.The hemagglutinating and mitogenic activities are inhibited by N-acetyl-D-galactosamine and some simple sugars.

Gram-negative bacteria have evolved an elaborate process for the recycling of their cell wall, which is initiated in the periplasmic space by the action of lytic transglycosylases. The product of this reaction, beta-d-N- acetylglucosamine-(1a?’4)-1,6-anhydro-beta-d-N-acetylmuramyl-l- Ala-I-d-Glu-meso-DAP-d-Ala-d-Ala (compound 1), is internalized to begin the recycling events within the cytoplasm. The first step in the cytoplasmic recycling is catalyzed by the NagZ glycosylase, which cleaves in a hydrolytic reaction the N-acetylglucosamine glycosidic bond of metabolite 1. The reactions catalyzed by both the lytic glycosylases and NagZ are believed to involve oxocarbenium transition species. We describe herein the synthesis and evaluation of four iminosaccharides as possible mimetics of the oxocarbenium species, and we disclose one as a potent (compound 3, Ki = 300 A± 15 nM) competitive inhibitor of NagZ.

Uridine 5?-diphosphate N-acetylglucosamine (UDP-GlcNAc) is a natural UDP-monosaccharide donor for bacterial glycosyltransferases, while uridine 5?-diphosphate N-trifluoacetyl glucosamine (UDP-GlcNTFA) is its synthetic mimic. The chemoenzymatic synthesis of UDP-GlcNAc and UDP-GlcNTFA was attempted by three recombinant enzymes. Recombinant N-acetylhexosamine 1-kinase was used to produce GlcNAc/GlcNTFA-1-phosphate from GlcNAc/GlcNTFA. N-acetylglucosamine-1-phosphate uridyltransferase from Escherichia coli K12 MG1655 was used to produce UDP-GlcNAc/GlcNTFA from GlcNAc/GlcNTFA-1-phosphate. Inorganic pyrophosphatase from E. coli K12 MG1655 was used to hydrolyze pyrophosphate to accelerate the reaction. The above enzymes were expressed in E. coli BL21 (DE3) and purified, respectively, and finally mixed in one-pot bioreactor. The effects of reaction conditions on the production of UDP-GlcNAc and UDP-GlcNTFA were characterized. To avoid the substrate inhibition effect on the production of UDP-GlcNAc and UDP-GlcNTFA, the reaction was performed with fed batch of substrate. Under the optimized conditions, high production of UDP-GlcNAc (59.51 g/L) and UDP-GlcNTFA (46.54 g/L) were achieved in this three-enzyme one-pot system. The present work is promising to develop an efficient scalable process for the supply of UDP-monosaccharide donors for oligosaccharide synthesis.

This paper describes the purification and characterization of a novel protein from the seeds of Pouteria torta (family Sapotaceae). The protein was purified by a combination of gel filtration, ion-exchange, and reverse phase chromatographies. SDS-PAGE of the purified protein resulted in a single protein band of 14 kDa in the presence and absence of DTT. The lectin-like activity of pouterin was best inhibited by glycoproteins such as fetuin, asialofetuin, heparin, orosomucoid, and ovoalbumin. Pouterin inhibited the growth of the fungi Fusarium oxysporum and Colletotrichum musae and of the yeast Saccharomyces cerevisiae. The incorporation of pouterin into an artificial diet (final concentration = 0.12%, w/w) caused 50% mortality in larvae of the insect Callosobruchus maculatus, whereas 0.08% pouterin produced an ED50.

O-Glycosidation of the totally O-unprotected aldoses (D-glucose, D-galactose and D-mannose) and D-fructose in THF or 1,4-dioxane using anhydrous FeCl3 as promoter afforded either aldofuranosides 1, 3, 4 in good overall yields or exclusively beta-D-fructopyranosides 7. Conversely alpha-D-aldopyranosides 2, 5 and 6 were obtained respectively from D-glucose, D-mannose and N-acetyl-D-glucosamine when the reactions were performed in the presence of BF3.OEt2 under ultrasonication.

The hydroxyl groups of carbohydrates are critical determinants of their conformational dynamics and intermolecular interactions but are difficult to characterize by conventional 1H nuclear magnetic resonance (NMR) approaches in solution. Here, we report a solid-state 17O NMR analysis of synthetic glucosamine with 17O enrichment at position 6. Based on magic-angle spinning and stationary spectral data obtained at varying magnetic fields in conjunction with quantum chemical calculations, we successfully estimated 17O chemical shift and electric field gradient tensors, providing benchmark for 17O NMR analyses of oligosaccharide structures.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Formula: C8H15NO6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 14215-68-0, in my other articles.

A green synthesis for beta-(1?3) galactosyldisaccharides that combines the use of a biodegradable biocatalyst, aqueous solutions, and solvent recycling (renewable and derived from biomass) has been developed. The use of biomass-derived solvents allows good catalytic activity in the synthesis of Gal-beta-d-(1?3)GlcNAc and Gal-beta-d-(1?)3GalNAc (99% and 95% yields respectively) with beta-Gal-3-NTag beta-galactosidase, preventing hydrolytic activity and with full regioselectivity. This represents a considerable improvement over the use of an aqueous buffer or conventional organic solvents. Furthermore, reaction scaling up and biosolvent recycling are feasible without losing catalytic action. In order to understand the role of these green solvents in the enzyme’s synthetic behaviour, different structural studies were performed (fluorescence and molecular modelling) in the presence of some selected biosolvents to conclude that the presence of green biosolvents in the reaction media modifies the enzyme’s tertiary structure allowing better substrate disposition in the active site, most probably due to solvation effects, explaining the behaviour observed.
