The structures of the asparagine-linked oligosaccharides of several variant forms of the vesicular stomatitis virus glycoprotein transiently expressed from cloned cDNAs have been determined. Glycopeptides isolated from forms of the G protein that reach the cell surface or that are secreted into the medium are virtually identical; they contain complex-type oligosaccharides whose nonreducing ends...
In an attempt to engineer a Yarrowia lipolytica strain to produce glycoproteins lacking the outer-chain mannose residues of N-linked oligosaccharides, we investigated the functions of the OCH1 gene encoding a putative alpha-1,6-mannosyltransferase in Y. lipolytica. The complementation of the Saccharomyces cerevisiae och1 mutation by the expression of YlOCH1 and the lack of in vitro alpha-1,6-ma...
Eight oligosaccharides were prepared from dermatan sulfate (DS) and their structures were elucidated. Porcine intestinal mucosal DS was subjected to controlled depolymerization using chondroitin ABC lyase (chondroitinase ABC). The oligosaccharide mixture formed was fractionated by low-pressure gel permeation chromatography (GPC). Size uniform mixtures of disaccharides, tetrasaccharides, hexasac...
to evaluatethe effects of supplementing diets of growing japanese quails (n=450; 7 days old) with chromium (cr) yeast and / or mannan oligosaccharides (mos) on productive performance, carcass traits and the immune system are reported. diets were a basal diet (control) or the basal diet supplemented with 600 mg cr-yeast/kg (cr 1), 1200 mg cr-yeast/kg (cr 2), 1.0 g mos/kg, cr 1 + mos or cr 2 + mo...
Abstract Banana production generates significant amounts of agricultural wastes, being fiber extraction one the most relevant alternatives for their valorization. This process produces banana’s pseudostem pulp (BPP) as a byproduct, which shows an interesting composition biorefinery’s biochemical platform, with high polysaccharides (68%) and low lignin contents. work deals enzymatic hydrolysis (...
The taste and mouthfeel of a wine are two the most important aspects tasting. However, while much is known about phenolic compounds other macromolecules direct effects on mouthfeel, little such as oligosaccharides. This experiment uses Fructo-oligosaccharide (FOS) Galacto-oligosaccharide (GOS) at different concentrations, 450 mg/L 900 within simple model matrix. A matrix was used to control for...
The fine structure of acharan sulfate, a recently discovered glycosaminoglycan isolated from Achatina fulica , was examined. This glycosaminoglycan has a major disaccharide repeating unit of -->4)-alpha-D-GlcNpAc(1-->4)-alpha-L-IdoAp2S(1--> (where GlcNpAc is N -acetylglucosamine, IdoAp is iduronic acid, and S is sulfate) making it structurally related to both heparin and heparan sulfate. Using ...
A new, powerful method is presented for screening the binding in real time and taking place under dynamic conditions of oligosaccharides to lectins. The approach combines an SPR biosensor and HPLC profiling with fluorescence detection, and is applicable to complex mixtures of oligosaccharides in terms of ligand-fishing. Labeling the oligosaccharides with 2-aminobenzamide ensures a detection lev...
Yersinia pestis is a Gram-negative bacterium that causes plague. After Y. pestis overcomes the skin barrier, it encounters antigen-presenting cells (APCs), such as Langerhans and dendritic cells. They transport the bacteria from the skin to the lymph nodes. However, the molecular mechanisms involved in bacterial transmission are unclear. Langerhans cells (LCs) express Langerin (CD207), a calciu...
The intracellular transport of newly synthesized lysosomal hydrolases to lysosomes requires the presence of one or more phosphorylated high mannose-type oligosaccharides per enzyme. A receptor that mediates mannose-6-PO4-specific uptake of lysosomal enzymes is expressed on the surface of fibroblasts and presumably accounts for the intracellular transport of newly synthesized enzymes to the lyso...
