Mannose inhibits Arabidopsis germination via a hexokinase-mediated step. (2/2363)

Low concentrations of the glucose (Glc) analog mannose (Man) inhibit germination of Arabidopsis seeds. Man is phosphorylated by hexokinase (HXK), but the absence of germination was not due to ATP or phosphate depletion. The addition of metabolizable sugars reversed the Man-mediated inhibition of germination. Carbohydrate-mediated regulation of gene expression involving a HXK-mediated pathway is known to be activated by Glc, Man, and other monosaccharides. Therefore, we investigated whether Man blocks germination through this system. By testing other Glc analogs, we found that 2-deoxyglucose, which, like Man, is phosphorylated by HXK, also blocked germination; no inhibition was observed with 6-deoxyglucose or 3-O-methylglucose, which are not substrates for HXK. Since these latter two sugars are taken up at a rate similar to that of Man, uptake is unlikely to be involved in the inhibition of germination. Furthermore, we show that mannoheptulose, a specific HXK inhibitor, restores germination of seeds grown in the presence of Man. We conclude that HXK is involved in the Man-mediated repression of germination of Arabidopsis seeds, possibly via energy depletion.  (+info)

Glycosylation of asparagine-28 of recombinant staphylokinase with high-mannose-type oligosaccharides results in a protein with highly attenuated plasminogen activator activity. (3/2363)

The properties of recombinant staphylokinase (SakSTAR) expressed in Pichia pastoris cells have been determined. The single consensus N-linked oligosaccharide linkage site in SakSTAR (at Asn28 of the mature protein) was occupied in approximately 50% of the expressed protein with high-mannose-type oligosaccharides. The majority of these glycans ranged in polymerization state from Man8GlcNAc2 to Man14GlcNAc2, with the predominant species being Man10GlcNAc2 and Man11GlcNAc2. Glycosylated SakSTAR (SakSTARg) did not differ from its aglycosyl form in its aggregation state in solution, its thermal denaturation properties, its ability to form a complex with human plasmin (hPm), the amidolytic properties of the respective SakSTAR-hPm complexes, or its ability to liberate the amino-terminal decapeptide required for formation of a functional SakSTAR-hPm plasminogen activator complex. However, this latter complex with SakSTARg showed a greatly reduced ability to activate human plasminogen (hPg) as compared with the same complex with the aglycosyl form of SakSTAR. We conclude that glycosylation at Asn28 does not affect the structural properties of SakSTAR or its ability to participate in the formation of an active enzymatic complex with hPm, but it is detrimental to the ability of the SakSTAR-hPm complex to serve as a hPg activator. This is likely due to restricted access of hPg to the active site of the SakSTARg-hPm complex.  (+info)

Genetic evidence for the role of GDP-mannose in plant ascorbic acid (vitamin C) biosynthesis. (4/2363)

Vitamin C (L-ascorbic acid; AsA) acts as a potent antioxidant and cellular reductant in plants and animals. AsA has long been known to have many critical physiological roles in plants, yet its biosynthesis is only currently being defined. A pathway for AsA biosynthesis that features GDP-mannose and L-galactose has recently been proposed for plants. We have isolated a collection of AsA-deficient mutants of Arabidopsis thaliana that are valuable tools for testing of an AsA biosynthetic pathway. The best-characterized of these mutants (vtc1) contains approximately 25% of wild-type AsA and is defective in AsA biosynthesis. By using a combination of biochemical, molecular, and genetic techniques, we have demonstrated that the VTC1 locus encodes a GDP-mannose pyrophosphorylase (mannose-1-P guanyltransferase). This enzyme provides GDP-mannose, which is used for cell wall carbohydrate biosynthesis and protein glycosylation as well as for AsA biosynthesis. In addition to genetically defining the first locus involved in AsA biosynthesis, this work highlights the power of using traditional mutagenesis techniques coupled with the Arabidopsis Genome Initiative to rapidly clone physiologically important genes.  (+info)

Alteration of mannose transport in fibroblasts from type I carbohydrate deficient glycoprotein syndrome patients. (5/2363)

The aim of the present study was to explore how mannose enters fibroblasts derived from a panel of children suffering from different subtypes of type I carbohydrate deficient glycoprotein syndrome: seven carbohydrate deficient glycoprotein syndrome subtype Ia (phosphomannomutase deficiency), two carbohydrate deficient glycoprotein syndrome subtype Ib (phosphomannose isomerase deficiency) and two carbohydrate deficient glycoprotein syndrome subtype Ix (not identified deficiency). We showed that a specific mannose transport system exists in all the cells tested but has different characteristics with respect to carbohydrate deficient glycoprotein syndrome subtypes. Subtype Ia fibroblasts presented a mannose uptake equivalent or higher (maximum 1.6-fold) than control cells with a D-[2-3H]-mannose incorporation in nascent N-glycoproteins decreased up to 7-fold. Compared to control cells, the mannose uptake was greatly stimulated in subtype Ib (4.0-fold), due to lower Kuptake and higher Vmax values. Subtype Ib cells showed an increased incorporation of D-[2-3H]-mannose into nascent N-glycoproteins. Subtype Ix fibroblasts presented an intermediary status with mannose uptake equivalent to the control but with an increased incorporation of D-[2-3H]-mannose in nascent N-glycoproteins. All together, our results demonstrate quantitative and/or qualitative modifications in mannose transport of all carbohydrate deficient glycoprotein syndrome fibroblasts in comparison to control cells, with a relative homogeneity within a considered subtype of carbohydrate deficient glycoprotein syndrome. These results are consistent with the possible use of mannose as a therapeutic agent in carbohydrate deficient glycoprotein syndrome Ib and Ix.  (+info)

Sugars and sugar derivatives which inhibit the short-circuit current of the everted small intestine of the rat. (6/2363)

1. The short-circuit current of everted rat intestine supported on a perforated cannula proved to be stable for up to 3 hr and has been used to study competition between transportable and non-transportable sugars. 2. 4,6-O-Ethylidene-alpha-D-glucopyranose (ethylidene glucose) and 4,6-O-benzylidene-e alpha-D-glucopyranos (benzylinene glucose), two nontransportable inhibitors of the hexose transfer system in human erythrocytes, were found to reduce the short-circuit current generated by transportable sugars such as galactose or 3-O-methyl glucose. 3. These compounds were also found to reduce the basal short-circuit current established by the everted intestine in a sugar-free Krebs solution. Both types of inhibition approached saturation at the higher concentrations used. 4. Similar inhibitory properties were shown by mannose, a non-actively accumulated monosaccharide, and by the beta-disaccharides lactose and cellobiose. 5. It is suggested that this common pattern of behaviour is due to the ability of these compounds to react with the sites for active hexose transfer but without translocation by the system. The significance of the inhibition of the basal short-circuit current is briefly discussed in this context.  (+info)

Transmembrane folding of the human erythrocyte anion exchanger (AE1, Band 3) determined by scanning and insertional N-glycosylation mutagenesis. (7/2363)

The human erythrocyte anion exchanger (AE1, Band 3) contains up to 14 transmembrane segments, with a single site of N-glycosylation at Asn642 in extracellular (EC) loop 4. Scanning and insertional N-glycosylation mutagenesis were used to determine the folding pattern of AE1 in the membrane. Full-length AE1, when expressed in transfected human embryonic kidney (HEK)-293 or COS-7 cells, retained a high-mannose oligosaccharide structure. Scanning N-glycosylation mutagenesis of EC loop 4 showed that N-glycosylation acceptor sites (Asn-Xaa-Ser/Thr) spaced 12 residues from the ends of adjacent transmembrane segments could be N-glycosylated. An acceptor site introduced at position 743 in intracellular (IC) loop 5 that could be N-glycosylated in a cell-free translation system was not N-glycosylated in transfected cells. Mutations designed to disrupt the folding of this loop enhanced the level of N-glycosylation at Asn743 in vitro. The results suggest that this loop might be transiently exposed to the lumen of the endoplasmic reticulum during biosynthesis but normally folds rapidly, precluding N-glycosylation. EC loop 4 insertions into positions 428, 484, 754 and 854 in EC loops 1, 2, 6 and 7 respectively were efficiently N-glycosylated, showing that these regions were extracellular. EC loop 4 insertions into positions 731 or 785 were poorly N-glycosylated, which was inconsistent with an extracellular disposition for these regions of AE1. Insertion of EC loop 4 into positions 599 and 820 in IC loops 3 and 6 respectively were not N-glycosylated in cells, which was consistent with a cytosolic disposition for these loops. Inhibitor-affinity chromatography with 4-acetamido-4'-isothiocyanostilbene-2,2'-disulphonate (SITS)-Affi-Gel was used to assess whether the AE1 mutants were in a native state. Mutants with insertions at positions 428, 484, 599, 731 and 785 showed impaired inhibitor binding, whereas insertions at positions 754, 820 and 854 retained binding. The results indicate that the folding of the C-terminal region of AE1 is more complex than originally proposed and that this region of the transporter might have a dynamic aspect.  (+info)

Recombinant human interleukin-12 is the second example of a C-mannosylated protein. (8/2363)

The beta-chain of human interleukin 12 (IL-12) contains at position 319-322, the sequence Trp-x-x-Trp. In human RNase 2 this is the recognition motif for a new, recently discovered posttranslational modification, i.e., the C-glycosidic attachment of a mannosyl residue to the side chain of tryptophan. Analysis of C-terminal peptides of recombinant IL-12 (rHuIL-12) by mass spectrometry and NMR spectroscopy revealed that Trp-319beta is (partially) C-mannosylated. This finding was extended by in vitro mannosylation experiments, using a synthetic peptide derived from the same region of the protein as an acceptor. Furthermore, human B-lymphoblastoid cells, which secrete IL-12, were found to contain an enzyme that carries out the C-mannosylation reaction. This shows that nonrecombinant IL-12 is potentially C-mannosylated as well. This is only the second report on a C-mannosylated protein. However, the occurrence of the C-mannosyltransferase activity in a variety of cells and tissues, and the presence of the recognition motif in many proteins indicate that more C-mannosylated proteins may be found.  (+info)

Xanthan has a particularly complicated molecular structure. however the backbone of xanthan is a β-(1-4)-D-glucose which is the same as cellulose. Every alternate glucose reside has a three sugar side chain consisting of two mannose residues with a glucuronic acid residue between them. The mannose reside nearest the main chain can carry a C6 acetyl group and the terminal mannose can carry a pyruvate group between C4 and C6. The acetylation and pyruvylation levels vary depending on fermentation conditions but typical values. Typically pyruvate residues can be found on 30-40% of the terminal mannose residues whereas 60-70% of the internal mannose residues may contain acetate groups. Recent work has looked at the properties of GM modified strains of xanthan gum that are either deficient in acetate groups, pyruvate groups or both. (Talashek).. Xanthan is produced in its native state as a twin stranded, right handed five fold helix. The stability of the helix is strongly affected by the ionic ...

cell cycle distribution and cisplatin‑mediated apoptosis of NSCLC cells. Transwell migration and invasion assays were conducted to examine whether mannose could inhibit the invasive abilities of NSCLC cells. The effects of mannose on the PI3K/AKT and ERK signalling pathways were explored through western blot analysis assessing the expression of phosphorylated (p)‑AKT and p‑ERK1/2. It was found that mannose showed potential anticancer effects against NSCLC cells in vitro by inhibiting proliferation, inducing G0/G1 cell cycle arrest, promoting cisplatin‑induced apoptosis and decreasing the invasive abilities. These data indicate the potential anticancer properties of mannose and suggest the application of mannose‑based therapies to treat NSCLC. ...
Deglycosylated IgE is shown for comparison (bottom right). An IgE Fab is highlighted (top right), showing Asn-140 and Asn-218 occupied by oligosaccharides in a single orientation. However, in vivo, glycans are very flexible; therefore, the sugar at Asn-168 is represented by a series of plausible conformational overlays to indicate the large surface area of the protein that can be shielded.

Mannose can randomize to glucose, galactose, and fucose. However, because the label in [3H]2-mannose is on the hydrogen of C-atom 2, the label would be predominantly found in mannose and fucose. In rare instances, the label from [3H]2-mannose can be found in glucose and lactic acid, suggesting that during oxidation and reduction reaction resulting in the epimerization of mannose to glucose, the label may be transferred from C-atom 2 to C-atom 1 (see Ref. 31). Thus, the major labeled spot in Fig. 1⇑ could be due to a glycan modifying a lipid and/or a protein. For three reasons we believe that the [3H]2-mannose-labeled compound is a glycolipid and not a glycopeptide or glycoprotein. First, the control Db-sol, also a glycoprotein with two N-linked glycans, processed in the same manner as sCD1d1, does not contain the tritiated spots seen with the CD1 sample (Fig. 1⇑). Second, the CD1d1-associated [3H]2-mannose-labeled ligands are PI-PLC sensitive as described below. Third, sialic acid-containing ...

I had a urinary infection and used the Mannose for one day thinking that was all I needed after reading info about the product. After that first day my symptoms were gone but I continued to take the Mannose the next day, but only a few teaspoons. My infection came back with a vengeance, I got a fever and it seemed that it was getting into my kidneys. I tried one antibiotic, cepro, took 2 pills and saw all the side effects and switched to another one. The next antibiodic didnt clear up the infection either although since I was taking one bottle a day of the Mannose and had no symptoms. As soon as I stopped the Mannose the symptoms returned. I went one more round with another antibiodic with no relief and stopped the Mannose so I could tell if the drugs were helping. They werent! Went to my naturopath and he recommended continuing with the mannose, the probiotics as well as his remedy which was to support the kidneys. I had also purchased the Jarrow Formulas, Fem-Dophilus, as I saw a series of ...

The fungal cell wall is the first point of interaction between an invading fungal pathogen and the host immune system. The outer layer of the cell wall is comprised of GPI anchored proteins, which are post-translationally modified by both N- and O-linked glycans. These glycans are important pathogen associated molecular patterns (PAMPs) recognised by the innate immune system. Glycan synthesis is mediated by a series of glycosyl transferases, located in the endoplasmic reticulum and Golgi apparatus. Mnn2 is responsible for the addition of the initial α1,2-mannose residue onto the α1,6-mannose backbone, forming the N-mannan outer chain branches. In Candida albicans, the MNN2 gene family is comprised of six members (MNN2, MNN21, MNN22, MNN23, MNN24 and MNN26). Using a series of single, double, triple, quintuple and sextuple mutants, we show, for the first time, that addition of α1,2-mannose is required for stabilisation of the α1,6-mannose backbone and hence regulates mannan fibril length. ...

The fact that D-mannose has the same configuration at its penultimate carbon as D-glyceraldehyde is unsurprising as that is what defines the dextro classification. However, mannose differs from D-glucose by inversion of the C2 chiral centre. This apparently simple change leads to the drastically different chemistry of the two hexoses, as it does the remaining six hexoses. ...

Title:Targeting the Mannose Receptor with Mannosylated Subunit Vaccines. VOLUME: 21 ISSUE: 30. Author(s):B. Sedaghat, R. Stephenson and I. Toth. Affiliation:School of Chemistry and Molecular Biosciences, The University of Queensland, St. Lucia, QLD, Australia.. Keywords:Dendritic cells, glycosyl, mannan, mannose receptor, peptide vaccine, targeting.. Abstract:The mannose receptor (MR) is an important component of the immune system and understanding the structural and conformational characteristics of this receptor is a key aspect of vaccine design. Improved understanding of the role of carbohydrate recognition domains 4-7 (CRDs 4-7) in recognising glycosylated ligands present on the surface of pathogens such as C.albicans, P. carinii, L. donovani, and M. tuberculosis has given new insight into MR vaccine development. Initial studies identified mannan and its derivatives to be important ligands in MR targeting, providing essential knowledge about the MR structural properties. The MR was found to ...

Mannose is part of the same family as glucose, sharing a similar molecular shape. So, the team were interested to see what happened when cells growing in the lab were also given mannose.. They studied the inner workings of different types of cancer cells and found that mannose didnt stop glucose being taken up by the cells, but it did stop them growing. They realised that mannose might be interfering with the way cancer cells break down glucose, stalling their growth.. To find out more, the team monitored the effects of feeding mannose to mice with cancer. Pancreatic cancers, skin cancers and lung cancers all stopped growing when the mice were given mannose supplements three times a week. There also seemed to be no effect on healthy cells.. Taking mannose did not significantly affect the weight or health of the mice, says Professor Kevin Ryan, who led the research.. However, our study didnt do a detailed analysis of every tissue, so it is not certain that mannose is completely safe.. The ...

Mannose Receptor, C type 1 (MRC1) is a membrane receptor that mediates the endocytosis of glycoproteins by macrophages. MRC1 binds mannose structures on the surface of viruses, bacteria, and fungi to be neutralized by phagocytosis. Changes in MCR1 have been associated with multiple diseases including the development of leprosy, sarcoidosis, Alzheimers disease, and asthma. Human has more copies of MRC1 than any other primate which could have had important implications for the multiple diseases that MRC1 may be involved in.. ...
β-mannosidase (EC 3.2.1.25, MANB) dissects the non-reducing end of N-linked mannose moieties of glycoproteins in eukaryotic cells. The human β-mannosidase gene was amplified by RT-PCR, cloned and sequenced. The DNA sequence was compared with reported human β-mannosidase DNA sequence and sixteen nucleotide differences were found. The deduced amino-acid sequence showed that seven codons coded the same amino acids and nine codons coded different amino acids with reference to nucleotide substitution positions but did not affect recombinant MANB enzyme activity. No splice mutation was observed after comparison with reported MANB DNA sequences. A 75% homology of deduced amino-acid sequence was observed with mouse, goat and bovine β-mannosidase amino-acid sequences. The cloned β-mannosidase gene was subcloned into pET22b+ and pET28a+ expression vectors to transform the BL21-codon plus cells for expression of recombinant MAN22 and MAN28 enzymes, respectively. The optimized conditions for ...

The reason? The tumours, hungry for glucose, were being starved. Mannose seems to get in the way.. The experiments suggest that mannose does not so much block glucose getting to the cancer cells but rather affect how those cells try to use the glucose.. A key sign that it is working is the presence of an enzyme called phosphomannose isomerase (PMI). Mannose is linked to lower levels of PMI in cancer cells.. The Beatson Institute researchers tested this aspect on human cancer cells in the lab.. Ovarian, kidney, breast, prostate and bowel cancer cells were among those tested. The lowest PMI levels were found with bowel cancer cells. Mice with the same cancer also developed significantly fewer tumours.. There are, however, significant caveats. This is not a cancer cure. It may not even be a treatment.. To move from this discovery to something that can be given to patients may take years.. ...
Chemical signaling between cells in multicellular organisms is frequently mediated by cell-surface receptors. The receptors for neurotransmitters, protein hormones, growth factors, and plant lectins are a few of the many known examples of these important membrane components. In this exercise, students examine the cell location and properties of the receptor for the lectin concanavalin A. In the first experiment of the series, students use a concanavalin A-peroxidase complex in a microscopic assay to show that the specific receptor is found on the surface of their own cheek epithelial cells. In the second part of the exercise, students study the characteristic hemagglutination reaction that is elicited by concanavalin A and learn that the reaction is due to multiple sites for receptor binding on the concanavalin A molecule. It is known that concanavalin A binds selectively to mannose residues on the cell-surface glycoprotein receptor. This specificity is confirmed in the final experiment of the ...

Clearance of various bacteria isolated from portal and systemic blood of mice was evaluated and compared. All portal blood strains, including Escherichia coli and enterococci were eliminated more rapidly from the circulation than were strains isolated from systemic blood, including Pseudomonas aeruginosa. With mannose-type lectin, mannose or fucose residues that mediated lectinophagocytosis were detected on the surfaces of most portal strains by agglutination tests. Blood clearance of Esch. coli H21 was inhibited by prior injection of mannose into mice, suggesting that the clearance of this strain was mediated by mannose-type lectin on the surface of tissue macrophages. However, no inhibition of clearance of any other strains was observed by the injection of mannose, galactose, or fucose into mice, nor by pre-incubation of bacteria with mannose. Blood clearance of some portal strains was significantly faster in CBA/J mice than in CBA/N mice with B cell immune deficiency, indicating that immunoglobulin

The interconversion of glucose, fructose and mannose in sodium carbonate-sodium bicarbonate buffer at pH 10.14 has been studied kinetically at 35 and 50° C. Degradation and the formation of other reducing substances also occur at significant rates and consideration of these reactions was necessary. The ratios of the three sugar concentrations become constant after a sufficient interval of time, and in these conditions the ratio [mannose]/ [glucose + fructose + mannose] was found to be 0.18 approximately, which is higher than has been previously reported. The reactions are shown to be first order in the concentrations of the three sugars, and the results are consistent with a mechanism in which these sugars form a common intermediate. The alternative mechanism, in which fructose is an intermediate in the interconversion of glucose and mannose, is not supported. A comparison with the experiments at much higher alkaiinities reported in parts I and II identifies the common intermediate with the ...

Eukaryotic phosphomannomutases (PMMs) catalyze the interconversion of mannose 6-phosphate to mannose 1-phosphate and are essential to the biosynthesis of GDP-mannose. As such, plant PMMs are involved in ascorbic acid (AsA) biosynthesis and N-glycosylation. We report on the conditional phenotype of the temperature-sensitive Arabidopsis thaliana pmm-12 mutant. Mutant seedlings were phenotypically similar to wild type seedlings when grown at 16-18 degrees C but died within several days after transfer to 28 degrees C. This phenotype was observed throughout both vegetative and reproductive development. Protein extracts derived from pmm-12 plants had lower PMM protein and enzyme activity levels.

Cyanovirin-N (CV-N) is an antiviral lectin with potent activity against enveloped viruses, including HIV. The mechanism of action involves high affinity binding to mannose-rich glycans that decorate the surface of enveloped viruses. In the case of HIV, antiviral activity of CV-N is postulated to require multivalent interactions with envelope protein gp120, achieved through a pseudo-repeat of sequence that adopts two near-identical glycan-binding sites, and possibly involves a 3D-domain-swapped dimeric form of CV-N. Here, we present a covalent dimer of CV-N that increases the number of active glycan-binding sites, and we characterize its ability to recognize four glycans in solution. A CV-N variant was designed in which two native repeats were separated by the

  • Also: "Human plasma contains ~50μM mannose which is primarily derived from N-glycan processing [19]. (cancercompass.com)
  • Many of the glycoproteins produced in the liver are secreted into the bloodstream, so dietary mannose is distributed throughout the body. (wikipedia.org)
  • citation needed] The digestion of many polysaccharides and glycoproteins yields mannose, which is phosphorylated by hexokinase to generate mannose-6-phosphate. (wikipedia.org)
  • The antibody 15-2 prevents binding of glycoproteins including t-PA to MR. Detection of the MR with anti-MR monoclonal antibody 15-2 can substitute staining for mannose containing probes as labeled mannosylated BSA, a technique which is more cumbersome and less specific. (novusbio.com)

  • MY mother suffered from recurrent UTIs until she started using D Mannose. (consumerlab.com)
  • The combination of D-mannose, inulin, cranberry, bearberry, Olea europaea, Orthosiphon and Lactobacillus acidophilus SGL 11 per os represents a useful therapy for recurrent UTIs. (greenmedinfo.com)
  • In this pilot study the aim was to evaluate if oral D Mannose could be used as a safe and effective treatment and as a prophylactic measure for recurrent UTIs in adult women. (clinicaltrials.gov)
  • D-mannose can help cure more than 90 percent of all UTIs within 1 to 2 days! (healthimpactnews.com)
  • Before discovering D-Mannose, I would get several UTIs a year and switch to either Bactrim or Levaquin to cure the infection. (allstarhealth.com)
  • I believe the D-Mannose is the reason I have less UTIs. (allstarhealth.com)
  • Biosynthesis of mammalian O-mannosyl glycans is initiated by the transfer of mannose from mannose-P-Dol to serine or threonine residue, followed by extensions with N-acetylglucosamine (GlcNAc) and galactose (Gal) to generate core M1, M2 and M3 glycans. (genome.jp)
