Protein or glycoprotein substances of plant origin that bind to sugar moieties in cell walls or membranes. Some carbohydrate-metabolizing proteins (ENZYMES) from PLANTS also bind to carbohydrates, however they are not considered lectins. Many plant lectins change the physiology of the membrane of BLOOD CELLS to cause agglutination, mitosis, or other biochemical changes. They may play a role in plant defense mechanisms.
Proteins that share the common characteristic of binding to carbohydrates. Some ANTIBODIES and carbohydrate-metabolizing proteins (ENZYMES) also bind to carbohydrates, however they are not considered lectins. PLANT LECTINS are carbohydrate-binding proteins that have been primarily identified by their hemagglutinating activity (HEMAGGLUTININS). However, a variety of lectins occur in animal species where they serve diverse array of functions through specific carbohydrate recognition.

Molecular characterization and crystallization of Diocleinae lectins. (1/1622)

Molecular characterization of seven Diocleinae lectins was assessed by sequence analysis, determination of molecular masses by mass spectrometry, and analytical ultracentrifugation equilibrium sedimentation. The lectins show distinct pH-dependent dimer-tetramer equilibria, which we hypothesize are due to small primary structure differences at key positions. Lectins from Dioclea guianensis, Dioclea virgata, and Cratylia floribunda seeds have been crystallized and preliminary X-ray diffraction analyses are reported.  (+info)

Lectins as membrane components of mitochondria from Ricinus communis. (2/1622)

1. Mitochondria were isolated from developing endosperm of Ricinus communis and were fractionated into outer membrane and inner membrane. The relative purity of the two membrane fractions was determined by marker enzymes. The fractions were also examined by negative-stain electron microscopy. 2. Membrane fractions were sequentially extracted in the following way. (a) Suspension in 0.5M-potassium phosphate, pH7.1; (b)suspension in 0.1M-EDTA (disodium salt)/0.05M-potassium phosphate, pH7.1; (c) sonication in 0.05M-potassium phosphate, pH7.1;(d)sonication in aq. Triton X-100 (0.1%). The membranes were pelleted by centrifugation at 100 000g for 15 min, between each step. Agglutination activity in the extracts was investigated by using trypsin-treated rabbit erythrocytes. 3. The addition of lactose to inner mitochondrial membrane resulted in the solubilization of part of the lectin activity, indicating that the protein was attached to the membrane via its carbohydrate-binding site. Pretreatment of the membranes with lactose before tha usual extraction procedure showed that lactose could extract lectins that normally required more harsh treatment of the membrane for solubilization. 4. Lectins extracted from inner membranes were purified by affinity chromatography on agarose gel. Polyacrylamide-gel electrophoresis of purified samples in sodium dodecyl sulphate indicated that at least part of the lectin present in inner mitochondrial membrane was identical with the R. communis agglutinin of mol.wt. 120 000.  (+info)

Post-translational processing of two alpha-amylase inhibitors and an arcelin from the common bean, Phaseolus vulgaris. (3/1622)

Mass spectrometric methods were used to investigate the proteolytic processing and glycopeptide structures of three seed defensive proteins from Phaseolus vulgaris. The proteins were the alpha-amylase inhibitors alphaAI-1 and alphaAI-2 and arcelin-5, all of which are related to the seed lectins, PHA-E and PHA-L. The mass data showed that the proteolytic cleavage required for activation of the amylase inhibitors is followed by loss of the terminal Asn residue in alphaAI-1, and in all three proteins, seven or more residues were clipped from the C-termini, in the manner of the seed lectins. In most instances, individual glycoforms could be assigned at each Asn site, due to the unique masses of the plant glycopeptides. It was found that alphaAI-1 and alphaAI-2 differed significantly in their glycosylation patterns, despite their high sequence homology. These data complement the previous X-ray studies of the alpha1-amylase inhibitor and arcelin, where many of the C-terminal residues and glycopeptide residues could not be observed.  (+info)

The distribution of sugar chains on the vomeronasal epithelium observed with an atomic force microscope. (4/1622)

The distribution of sugar chains on tissue sections of the rat vomeronasal epithelium, and the adhesive force between the sugar and its specific lectin were examined with an atomic force microscope (AFM). AFM tips were modified with a lectin, Vicia villosa agglutinin, which recognizes terminal N-acetyl-D-galactosamine (GalNAc). When a modified tip scanned the luminal surface of the sensory epithelium, adhesive interactions between the tip and the sample surface were observed. The final rupture force was calculated to be approximately 50 pN based on the spring constant of the AFM cantilever. Distribution patterns of sugar chains obtained from the force mapping image were very similar to those observed using fluorescence-labeled lectin staining. AFM also revealed distribution patterns of sugar chains at a higher resolution than those obtained with fluorescence microscopy. Most of the adhesive interactions disappeared when the scanning solution contained 1 mM GaINAc. The adhesive interactions were restored by removing the sugar from the solution. Findings suggest that the adhesion force observed are related to the binding force between the lectin and the sugars distributed across the vomeronasal epithelium.  (+info)

A gene encoding a hevein-like protein from elderberry fruits is homologous to PR-4 and class V chitinase genes. (5/1622)

We isolated SN-HLPf (Sambucus nigra hevein-like fruit protein), a hevein-like chitin-binding protein, from mature elderberry fruits. Cloning of the corresponding gene demonstrated that SN-HLPf is synthesized as a chimeric precursor consisting of an N-terminal chitin-binding domain corresponding to the mature elderberry protein and an unrelated C-terminal domain. Sequence comparisons indicated that the N-terminal domain of this precursor has high sequence similarity with the N-terminal domain of class I PR-4 (pathogenesis-related) proteins, whereas the C terminus is most closely related to that of class V chitinases. On the basis of these sequence homologies the gene encoding SN-HLPf can be considered a hybrid between a PR-4 and a class V chitinase gene.  (+info)

Selective killing of CD8+ cells with a 'memory' phenotype (CD62Llo) by the N-acetyl-D-galactosamine-specific lectin from Viscum album L. (6/1622)

As reported previously by our group, among the toxic proteins from Viscum album L. only the mistletoe lectins (MLs) induce the apoptotic killing pathway in human lymphocytes. Although one may expect a homogenous distribution of carbohydrate domains on cell surface receptors for the carbohydrate binding B chains of the toxic protein, the sensitivity of cells to these B chains obviously differ. Here we report a selective killing of CD8+ CD62Llo cells from healthy individuals by the galNAc-specific ML III (and RCA60, which binds to gal and galNAc), while the gal-specific ML I was less effective. This selective killing is not sufficiently explained by protein synthesis inhibition alone, since this subset was not affected by other ribosome inhibiting proteins such as the lectin from Ricinus communis (RCA120), lectin from Abrus precatorus (APA), abrin A, and inhibitors of RNA, DNA and/or protein synthesis such as actinomycin D, mitomycin C, and cycloheximide. We conclude that CD8+ cells with 'memory' phenotype (CD62Llo) are more sensitive to the ML III-mediated killing than their CD8+ CD62Lhi counterparts, CD4+ T cells, and CD19+ B cells. These cells probably express a distinct receptor with galNAc domains that is missing or not active on CD8+ cells with a 'naive' phenotype.  (+info)

Underglycosylation of IgA1 hinge plays a certain role for its glomerular deposition in IgA nephropathy. (7/1622)

This study was performed to isolate and investigate the IgA1 that could accumulate in glomeruli (glomerulophilic IgA1). IgA1 was fractionated by the electric charge and the reactivity to Jacalin. Serum IgA1 of IgA nephropathy patients was separated and fractionated using a Jacalin column and subsequent ion-exchange chromatography. The fractions were divided into three groups of relatively cationic (C), neutral (N), and anionic (A). IgA1 was also divided into Jacalin low (L), intermediate (I), and high (H) affinity fractions by serial elution using 25, 100, and 800 mM galactose. The left kidneys of Wistar rats were perfused with 2, 5, or 10 mg of each group of IgA1. The rats were sacrificed 15 min, 30 min, 3 h, or 24 h after the perfusion. The accumulation of each IgA1 in the glomeruli was then observed by immunofluorescence. The IgA1 of the fractions N and H separated by the two methods was definitely accumulated in the rat glomeruli with a similar pattern. The electrophoresis revealed that the macromolecular IgA1 was increased in fraction H compared with other fractions. Therefore, Jacalin high-affinity IgA1(fraction H) was applied on a diethylaminoethyl column and divided into electrically cationic (HC), neutral (HN), and anionic (HA). Only the asialo-Galbeta1,3GalNAc chain was identified in the fraction HN IgA1 by gas-phase hydrazinolysis. Furthermore, the IgA1 fraction was strongly recognized by peanut agglutinin, Vicia Villosa lectins, and antisynthetic hinge peptide antibody. These results indicated that the IgA1 molecules having the underglycosylated hinge glycopeptide played a certain role in the glomerular accumulation of IgA1 in IgA nephropathy.  (+info)

Vicia faba agglutinin, the lectin present in broad beans, stimulates differentiation of undifferentiated colon cancer cells. (8/1622)

BACKGROUND: Dietary lectins can alter the proliferation of colonic cells. Differentiation is regulated by adhesion molecules which, being glycosylated, are targets for lectin binding. AIMS: To examine the effects of dietary lectins on differentiation, adhesion, and proliferation of colorectal cancer cells. METHODS: Differentiation was assessed in three dimensional gels, adhesion by aggregation assay, and proliferation by 3H thymidine incorporation. The role of the epithelial cell adhesion molecule (epCAM) was studied using a specific monoclonal antibody in blocking studies and Western blots. The human colon cancer cell lines LS174T, SW1222, and HT29 were studied. RESULTS: The cell line LS174T differentiated in the presence of Vicia faba agglutinin (VFA) into gland like structures. This was inhibited by anti-epCAM monoclonal antibody. Expression of epCAM itself was unaffected. VFA as well as wheat germ agglutinin (WGA) and the edible mushroom lectin (Agaricus bisporus lectin, ABL) significantly aggregated LS174T cells but peanut agglutinin (PNA) and soybean agglutinin (SBA) did not. All lectins aggregated SW1222 and HT29 cells. Aggregation was blocked by the corresponding sugars. Aggregation of cells by VFA was also inhibited by anti-epCAM. VFA, ABL, and WGL inhibited proliferation of all the cell lines; PNA stimulated proliferation of HT29 and SW1222 cells. In competition studies all sugars blocked aggregation and proliferation of all cell lines, except that the addition of mannose alone inhibited proliferation. CONCLUSION: VFA stimulated an undifferentiated colon cancer cell line to differentiate into gland like structures. The adhesion molecule epCAM is involved in this. Dietary or therapeutic VFA may slow progression of colon cancer.  (+info)

Lectins, a well-known class of carbohydrate-binding proteins, are known to be important in a variety of biological processes, mediated through their carbohydrate specificities. Plant lectins are broadly divided into six classes based on their subunit folds. These are legume lectins (see ,PDOC00278,), jacalin-related lectins (JRLs), monocot mannose-binding lectins (see ,PDOC50927,), trefoil lectins, cyanovirin-N lectin, and hevein domain lectins. JRLs derive their name from jacalin, the first member to be identified from the seed of jackfruit. Based on the known sugar specificities, lectins in this family can be broadly divided into two classes: (1) the galactose-specific lectins and (2) the mannose/glucose-specific lectins [1,2,3,4,5]. The ~135-150 amino acid residue jacalin-type lectin domain adopts a β-prism-I fold comprised of three Greek keys (four stranded β-sheets) (see ,PDB:3APA,) [4]. Some proteins known to contain a jacalin-type lectin domain are listed below: ...
Nephrotoxicity is one of the most common kidney conditions. However, most conventional drugs are not adequate for treatment. This study was designed to evaluate the nephroprotective activity of 50% hydroethanolic leaf extract of Griffonia simplicifolia (DC.) Benth in drug-induced nephrotoxicity in Sprague-Dawley rats. Nephrotoxicity was induced in experimental animals by administering gentamicin and cisplatin after pretreatment with hydroethanolic extract of G. simplicifolia (GSE). GSE at 100 and 250 mg/kg were administered for 7 and 10 days by oral gavage in the gentamicin and cisplatin models, respectively. Silymarin (120 mg/kg) was given as the standard nephroprotective drug. Nephroprotective effect was studied by assaying the activity of kidney function biomarkers such as creatinine, urea, sodium, chloride, and potassium concentrations. The effect of the treatments on kidney antioxidant enzymes (SOD, MDA, GSH, GPx, GST and NO), inflammatory cytokines (IL 17, IL 23 and COX-2) and the ...

The role of individual carbohydrate-binding sites in the function of the potent anti-HIV lectin Griffithsin. Jie Xue, Yongguang Gao, Bart Hoorelbeke, Ioannis Kagiampakis, Bo Zhao, Borries Demeler, Jan Balzarini, and Patricia J. LiWang Molecular Pharmaceutics 4, 2613-2625 (2012).. Griffithsin (GRFT) is a lectin that has been shown to inhibit HIV infection by binding to high mannose glycan structures on the surface of gp120, and is among the most potent HIV entry inhibitors reported so far. However, important biochemical details on the antiviral mechanism of GRFT action remain unexplored. In order to understand the role of the three individual carbohydrate-binding sites (CBS) in GRFT, mutations were made at each site (D30A, D70A, and D112A), and the resulting mutants were investigated. NMR studies revealed that each GRFT variant was folded but showed significant peak movement on the carbohydrate-binding face of the protein. The wild-type and each point mutant protein appeared as tight dimers with ...
The legume lectins (or L-type lectins) are a family of sugar-binding proteins or lectins found in the seeds and, in smaller amounts, in the roots, stems, leaves and bark of plants belonging to the Fabaceae family. The exact function of the legume lectins in vivo is unknown but they are probably involved in the defense of plants against predators. Related proteins in other plant families and in animals have also been found. They have been used for decades as a model system for the study of protein-carbohydrate interactions, because they show an amazing variety of binding specificities and are easy to obtain and purify. Over the years, a quite impressive amount of structural data has been gathered. Well-studied members of this protein family include phytohemagglutinin and concanavalin A. The legume lectins use an ingenious framework for binding specific sugars. This framework consists of a conserved monosaccharide binding site in which four conserved residues from four separate regions in the ...

Ploidy determination and mutation breeding of crop plants are inseparable twins given that mutation breeding is hinged majorly on polyploidization of crops chromosome number. The present research was aimed at determining the ploidy level of 20 accessions of winged bean (Psophoscarpus tetragonolobus) using known diploid standard as control and also subjecting two accessions to colchicine mutagenesis. For flow cytometric analysis, approximately 50mm2 of young fresh intact leaves of 8 weeks post-seedling emergence from the 20 accessions were used. Crude isolation of nuclei was done by chopping the leaf in 1ml of ice cold buffer from DNA kit (cysteine UV Partec GmbH Germany) using a razor blade. The crude suspension was then filtered through a 30μm pore diameter nylon mesh and stained with 4,6- diaminodino-2-phenylindole (DAPI). Fluorescence intensity of isolated nuclei was measured using a partec PAII flow cytometry equipped with an argon ion laser at 488nm.For mutation induction, 20 seeds from ...

S (2008) 333:353Many but not all ret-positive cells shed trkA expression postnataly and bind the lectin, Griffonia simplicifolia isolectin B4 Postnatally, neurons coexpressing ret and trkA, as analysed by double ISH, undergo trkA extinction, which appears to be full at P14 (Luo et al. 2007). This method is ret-dependent as it is slowed down in ret mutants. Conversely, ret expression is NGF-dependent as, in NGF/Bax (bcl-2 connected pro-apoptotic protein) double-mutants, only some ret-positive neurons are present at P0 and these are trkA-negative (Luo et al. 2007). In mature animals, the overlap of ret and trkA expression is limited and amounts to 5 five in mouse lumbar segment 5 (L5) DRG (Molliver et al. 1997; Orozco et al. 2001). In adult rat, 26 eight of trkA-positive cells in lumbar DRG express ret and 15 of ret-positive cells express trkA (Bennett et al. 1998; Kashiba et al. 1998, 2003). A total of 9 of DRG neurons express both. Roughly half of trkB- and trkCpositive cells express ret ...
If regularly used, 5-HTP should be taken at night and L-Tyrosine in the morning. These two precursors to neurotransmitters work together and are needed to keep the neurotransmitters Dopamine at the correct level.

Bead- and column-based separation methods rely heavily on the speed and ease of affinity binding systems. Ligands such as streptavidin, antibodies and lectins are used both to capture specifically-tagged targets and for the isolation of cells and biomolecules that naturally express the ligand binding partner. The unique saccharide-binding properties of plant lectins, such as Concanavalin A (Con A) have made them useful for the labeling and isolation of glycan-presenting cells and glycoproteins in serum and cell lysate. Lectins have additionally been used in cell adhesion studies, to effect lymphocyte activation, and to explore carbohydrate-based therapeutics.. Learn More ...

The HLA--Bw4 and Bw6 antigenic determinants have been shown to co-migrate with HLA--B determinants on gel-filtration, sucrose density gradient centrifugation and affinity chromatography, using Lens culinaris lectin and antibody against human beta 2 microbulin. These and other published data imply that the HLA--Bw4 and Bw6 determinants reside on the same polypeptide chain as other HLA--B locus determinants. The implications of this in terms of the evolution of cross reacting groups of antigens at the HLA--B locus are discussed.
According to their sugar recognition specificity, plant lectins are proposed as bioactive proteins with potential in cancer treatment and diagnosis. Helja is a mannose-specific jacalin-like lectin from sunflower which was shown to inhibit the growth of certain fungi. Here, we report its recombinant expression in a prokaryotic system and its activity in neurobalstoma cells. Helja coding sequence was fused to the pET-32 EK/LIC, the enterokinase/Ligation-independent cloning vector and a 35 kDa protein was obtained in Escherichia coli representing Helja coupled to thioredoxin (Trx). The identity of this protein was verified using anti-Helja antibodies. This chimera, named Trx-rHelja, was enriched in the soluble bacterial extracts and was purified using Ni+2-Sepharose and d-mannose-agarose chromatography. Trx-rHelja and the enterokinase-released recombinant Helja (rHelja) both displayed toxicity on human SH-SY5Y neuroblastomas. rHelja decreased the viability of these tumor cells by 75% according to the

TY - JOUR. T1 - Distribution of Bandeiraea simplicifolia lectin binding sites in the genital organs of female and male mice. AU - Wu, T. C.. AU - Wan, Yu-Jui Yvonne. AU - Damjanov, I.. PY - 1983/6. Y1 - 1983/6. N2 - Fluorescein isothiocyanate labelled type I lectin from Bandeiraea simplicifolia (BSA-I) known for its specific binding to α-d-galactopyranosyl and 2-acetamido-2-deoxy-d-galactose groups, has been used to map the distribution of the lectin specific binding sites in the genital organs of female and male mice. In non-pregnant female mice, strong lectin reactivity was restricted to the epithelium of the distal oviduct, the cervix and vagina. In pregnant mice strong BSA-I reactivity was also noted in the epithelium of uterine glands from the time of implantation on day 5 onward. In the testis BSA-I bound selectively to sperm but did not react with other cells in the seminiferous tubules. In the proximal caput epididymis BSA-I reacted with the epithelial cells, the underlying basement ...
Enhances brain serotonin 5-Hydroxytryptophan (5-HTP) is an intermediate in the natural synthesis of the essential amino acid, tryptophan, to serotonin. The enzyme tryptophan hydroxylase adds a hydroxyl group (OH) to tryptophan, forming the 5-HTP intermediate. In the body, it converts to serotonin with the removal of a carboxyl group (COOH) by a second enzyme. Serotonin is an important neurotransmitter involved in the regulation of endocrine and brain activity responsible for emotion, appetite and sleep/wake cycles. In clinical studies, administration of 5-HTP supported serotonin production. The 5-HTP supplied in this supplement is derived from the Griffonia simplicifolia plant. Supplementation with 5-HTP encourages brain serotonin levels that can lead to positive effects on emotional well-being, appetite control, and wake/sleep cycles. each vegetable capsule contains: 5-hydroxytryptophan (Griffonia simplicifolia) 100 mg. (hypo-allergenic plant fiber added to complete capsule
Jacalin, isolated by affinity chromatography from jackfruit seeds, belongs to the family of galactose-binding lectins. Jacalin is a tetrameric two-chain lectin with a molecular weight of 66 kDa. Applications include isolating IgA from human serum, isolating human plasma glycoproteins and histochemistry. A post-translational proteolytic modification of Jacalin gives the lectin a novel carbohydrate-binding site involving the N terminus of the alpha-chain. The relative affinities of the lectin for galactose derivatives, as well as the structural basis of its T-antigen specificity, are explained by its protein structure. Artocarpus integrifolia lectin is supplied without preservatives as a lyophilized white to light-yellow powder, essentially salt-free. For laboratory use only.
The motility and the chemotactic response towards plant roots of Radopholus similis, after treatment with novel types of lectins, were examined in vitro by analysing movement tracks on agar plates. Six plant lectins belonging to five different lectin families and a banana thaumatin-like protein (BanTLP) were included in the experiment. A 1% concentration of Phaseolus vulgaris agglutinin (PHA) had an adverse effect on the motility of R. similis females: 63% showed no or very little movement on agar plates compared to an average of 33% for other lectins and 3% for the control treatment. A 0.05% concentration of PHA still reduced the motility of R. similis females by 75%. Concanavalin A and wheat germ agglutinin did not alter the chemotactic response towards plant roots, despite binding of both lectins to R. similis. In contrast, Galanthus nivalis agglutinin (GNA) reduced orientated movement of R. similis towards plant roots. Subsequently, secretions of R. similis were stained with Coomassie Brilliant Blue
Dolichos biflorus|/em| agglutinin is a glycoprotein with a molecular weight of about 111 kDa and consists of 4 subunits of approximately equal size. This lectin has a carbohydrate specificity toward α-linked N-acetylgalactosamine.
The mannose-binding lectin from snowdrop (Galanthus nivalis agglutinin; GNA) was produced in Escherichia coli and purified as a functional protein after denturation/renaturation. Incorporation of the four extra C-terminal residues recently revealed from X-ray crystallographic data demonstrated that these residues increase binding to the glycoprotein carboxypeptidase Y. However, no differences in activities were observed in haemagglutination assays when compared to native GNA and toxicity towards rice brown planthopper (Nilaparvata lugens, BPH) in artificial diet bioassays was unaltered. Site-directed mutagenesis of the carbohydrate-binding site of GNA provided evidence of a direct correlation between the binding potential of GNA to BPH gut glycoprotein receptors and the toxicity levels of GNA towards BPH nymphs. Functional recombinant plant lectins GNA and PHA (Phaseolus vulgaris agglutinin) were expressed in Pichia pastoris using native signal peptides or the Saccharomyces a-factor ...

Carbohydrate-binding agents (CBAs), such as the plant lectins Hippeastrum hybrid agglutinin (HHA) and Urtica dioica agglutinin (UDA), but also the nonpeptidic antibiotic pradimicin A (PRM-A), inhibit entry of HIV into its target cells by binding to the glycans of gp120. Given the high sequence identity and similarity between the envelope gp120 glycoproteins of HIV and simian immunodeficiency virus (SIV), the inhibitory activity of a variety of CBAs were evaluated against HIV-1, HIV-2, and SIV. There seemed to be a close correlation for the inhibitory potential of CBAs against HIV-1, HIV-2, and SIV replication in cell culture and syncytia formation in cocultures of persistently SIV-infected HUT-78 cell cultures and uninfected CEM cells. CBAs also inhibit transmission of the SIV to T lymphocytes after capture of the virus by dendritic cell-specific ICAM3-grabbing nonintegrin (DC-SIGN)-expressing cells. A total of 8 different SIV strains were isolated after prolonged HHA, UDA, and PRM-A exposure in ...

The structures of MornigaM and the MornigaM-mannose complex have been determined at 1.8 A and 2.0 A resolution, respectively. Both structures adopt the typical beta-prism motif found in other jacalin-related lectins and their tetrameric assembly closely resembles that of jacalin. The carbohydrate-binding cavity of MornigaM readily binds mannose. No major structural rearrangements can be observed in MornigaM upon binding of mannose. These results allow corroboration of the structure-function relationships within the small group of Moraceae lectins ...

Dr. Pusztai lost his job with RRI for expressing his opinions on the safety of genetically modified foods in a TV interview in 1998, while doing research on potatoes enhanced with Galanthus nivalis agglutinin, or GNA for short. GNA is a plant lectin derived from Galanthus nivalis, commonly known as Snowdrops (see picture below). Lectin is a protein usually derived from plants that has antibody properties (helps protect the plant from infection or disease). The experiments he was reporting on were testing on the effects of GNA, and the effects of the GM potato when supplemented to the diets of rats. He found when GNA was mixed in with the rats food as a protein supplement, there were no harmful effects. However, when the GM potato (modified with the GNA) was fed to the rats, it hindered growth as well as having other adverse effects. Pusztai said in a 2000 interview with the Canadian Health Coalition that many harmless substances when genetically altered, can become harmful (Interview with ...

Humans dont have the proper enzymes necessary to digest lectins.. As they pass through the stomach, lectins remain largely unaltered. When they reach the intestines, they can attach to the lining of the gut (6).. In one study that was conducted on rodents, lectins made it through the stomach and attached themselves to the small intestines.. They temporarily thickened the walls of the small intestines, affecting their ability to absorb nutrients.. They also changed the length and function of the entire digestive tract. These effects were mostly reversed upon elimination of lectin from the diet (7).. Lectins can enhance pancreas growth and increase the release of digestive enzymes (8).. Lectins make it difficult for the body to maintain its own cells.. Therefore, people with damage from lectins may experience more digestive problems. This may occur gradually (9, 10).. Phytohaemagglutinin are the most commonly studied lectins. Kidney beans are one of the main sources of these proteins.. If you eat ...

... (Vietnamese: [tɨəŋ]) is the name applied to a variety of condiments a kind of fermented bean paste made from soybean and commonly used in Vietnamese cuisine. Originally, the term tương refers to a salty paste made from fermented soybeans, which is popular in vegetarian meals, particularly those prepared and eaten by Vietnamese Buddhist monks. It is also the most typical dipping sauce for summer rolls (gỏi cuốn). The paste, which is generally dark brown in color, is produced by adding the fungus Aspergillus oryzae to roasted soybeans, which are then allowed to naturally ferment in a jar with water until it develops an umami flavor. Other ingredients, such as glutinous rice or maize powder, salt, or water, may also be used. Tương is similar to the Chinese yellow soybean paste, though the latter is generally saltier and thicker in texture. Tương may range in consistency from a thick paste to a thin liquid. Some varieties, such as that prepared in Central Vietnam, are watery, ...

By layering and bunching the sheets in a certain manner, an imitation of chicken breast can be created with yuba. The effect is completed by frying the "skin" side of the tofu chicken until it is crispy. If stuffed with vegetables, it becomes tofu duck. Likewise various other meat alternatives have been made in this way, especially by Buddhist vegetarian restaurants in areas of Chinese culture.[3] The world's first meat analogs were developed in China, probably by Buddhist cooks in temples and monasteries.[4] The earliest process for making these meatless meats consisted of rolling thin sheets of doufupi, literally tofu skin, around a filling of minced, smoked, or other seasoned pieces of tofu skin, tying closed the bundle with string, and steaming until a meaty texture and flavor developed.[4] ...
The Tofurky roast is found in health food grocery stores; however, availability is limited in some areas. Inside the box, it comes in the form of a small but dense roast, wrapped tightly in a disposable casing, and is something of a rounded loaf in shape. It comes stuffed with mushrooms, herbs, and wild rice. Though the roast can be purchased separately, it is also offered as part of a meal with cranberry-apple-potato dumplings, gravy, and "wishstix"[4] made from Tofurky Jurky, a meatless jerky product. The Whole Foods store chain is a major seller of Tofurky products. Tofurky is a popular meat alternative[5] amongst many vegetarians, who avoid turkey for ethical and/or personal reasons. The product is free from turkey and other meat products. ...

  • What common foods contain lectins? (
  • However, a wide variety of foods contain lectins, not just legumes. (
  • Truth be told, nearly every type of food - including some fruits and vegetables, fungi, and more, have varieties that contain lectins. (
  • Does Organic Plant Protein contain Lectins? (
  • Because we source the main ingredients of our Organic Plant Protein from whole plant foods (sunflower, pumpkin, and pea) they do contain lectins. (
  • It is also interesting to note that many of the foods that are excluded in the low FODMAP diet are those that also contain lectins. (
  • But there's a secret about this amazing source of protein… Though beans do contain lectins, if you pressure cook them, you can actually kill almost all of the lectins inside them. (
  • The other nutrients in foods that contain lectins are so beneficial, that unless you have an intolerance, you should actually be eating them for better nutrition and managing your weight. (
  • Plant lectins are bioactive glycoproteins possessing carbohydrate-recognition domain which exhibit regiospecific, cell-surface specific and reversible interactions with glycoconjugates. (
  • Affinity purification of human, plant and fungal glycoproteins on immobilized C. sepium lectin demonstrates that this novel lectin can be used for the isolation of glycoconjugates from various sources. (
  • Lectins are natural, not synthetic, products (proteins) and target the sugar moieties of a wide variety of glycoproteins. (
  • These lectins are glycoproteins with Glu/Man carbohydrate determinants. (
  • L-type lectins have different intracellular distributions and dynamics in the ER-Golgi system of secretory pathway and interact with N-glycans of glycoproteins in a Ca 2+ -dependent manner, suggesting a role in glycoprotein sorting and trafficking. (

(
  • Hapten inhibition studies indicate that the novel lectin is best inhibited by maltose and mannose and hence exhibits a sugar binding specificity that differs in some respects from that of all previously isolated plant lectins. (
  • Moreover, it can be expected that by virtue of its distinct specificity, the new lectin will become an important tool in glycobiology. (
  • Because of their similar D-mannose/D-glucose specificity, these lectins interacted with lipopolysaccharides and exopolysaccharides of Rhizobium leguminosarum bv. (
  • This finding permits a conclusion that pollen grain wall contains lectins differing in their carbohydrate specificity. (
  • The data from this work strongly suggested the change in affinity and specificity of placental IR and IGFRs for the homologous and heterologous ligands, under the influence of specific plant lectins. (
  • The fact that some plant lectins can modulate the interaction of placental IR and IGFRs with their ligands may imply the existence of placental lectins of the similar sugar specificity with the same function. (
  • Due to the obvious differences in molecular structure, biochemical properties, and carbohydrate-binding specificity, plant lectins are usually considered a complex and heterogeneous group of proteins. (
  • The size, shape and specificity of the sugar-binding site of the jacalin-related lectins is profoundly affected by the proteolytic cleavage of the subunits. (
  • More specifically, the study aimed to determine the lectin's blood group specificity and pH stability, determine effects of seasonal variation, soil moisture and soil pH on lectin activity. (
  • The motility and the chemotactic response towards plant roots of Radopholus similis , after treatment with novel types of lectins, were examined in vitro by analysing movement tracks on agar plates. (
  • However, for the majority of people, most types of lectins in our foods present no issues with proper preparation and simple cooking. (
  • To start, cooking almost completely neutralizes the more problematic types of lectins. (
  • While many types of lectins cause negative reactions in the body, there are also health promoting lectins that can decrease incidence of certain diseases. (
  • While these forms are the most common, PHA from red kidney beans can be divided into a family of 5 lectins [ 11 ]. (
  • This approach was used by Nachbar and Oppenheim in 1980 when they reported that lectins were present in >20 common food commodities including potatoes, carrots, tomatoes, beans and peas. (
  • This action of lectins is most likely a contributing factor to the pro-weight loss and anti-diabetes effects of beans and other plant foods. (
  • And that's not the only one: similar results have been found for lectins from fava beans, soybeans, bananas, buckwheat, jackfruit, and wheat. (
  • Red kidney beans contain phytohaemagglutinin, a type of lectin that can cause red blood cells to clump together. (
  • However, when these beans are cooked, the harmful lectins are denatured and no longer pose a threat. (
  • Since red kidney beans and legumes, in general, are not consumed raw, their lectin content is nothing to be concerned about. (
  • Raw kidney beans contain from 20,000 to 70,000 lectin units, while fully cooked beans usually contain between 200 and 400 units. (
  • It is acceptable to have a theory, but this idea about lectins being "disease-causing" and that people need to avoid beans, vegetable and nuts in order to get healthy and lose weight, has been thoroughly disproven by the thousands of studies documenting the health and longevity benefits of these foods. (
  • A lectin called phytohemagglutinin found in raw beans (red kidney beans in particular) binds to a carbohydrate present on human intestinal cells. (
  • The same cooking process that reduces the gas-causing tendencies of beans also reduces their lectin content to a safe level. (
  • Canned beans have been prepared using this process, so they are not high in lectins. (
  • Green (immature) beans and peas have low levels of lectins. (
  • Uncooked (raw) legumes like kidney beans are the biggest sources of these lectins. (
  • Eating raw kidney beans can lead to lectin poisoning, the main symptoms of which include severe abdominal pain, vomiting and diarrhea ( 8 ). (
  • In one study, lectins in soybeans were mostly eliminated when the beans were boiled for only 5 to 10 minutes ( 14 ). (
  • So the three main pathogenic factors for peptic ulcer-acid stimulation, failure of the mucous defence layer, and abnormal bacterial proliferation ( Helicobacter pylori ) are all theoretically linked to lectins. (
  • Indeed, researchers speculate that many apparent causes of bacterial food poisoning may actually be lectin poisoning. (
  • Four main groups of Pseudomonas bacteriocins have been identified so far, all of which equally occur in other bacterial genera: tailocins, modular bacteriocins, B-type microcins and lectin-like bacteriocins (Supplementary Table S1 ). (
  • Pre-incubation of propionibacteria with lectins prevented these effects, which could be ascribed to the binding of lectins by bacterial cells since P. acidipropionici CRL 1198 was unable to metabolize these proteins, and its adhesion to colonic cells was reduced after reaction with Con A or AIL. (
  • Also, bacterial infections, inflammatory bowel disease (IBD), colon cancer, or autoimmune illnesses may alter intestinal cells in a way that makes usually harmless food lectins problematic. (
  • Lectins are proteins that are in general resistant to low pH in the stomach and to proteolytic enzymes in the small intestine, and for some of these molecules >90% can survive passage through the gut. (
  • Lectins offer a way for molecules to stick together without getting the immune system involved, which can influence cell-cell interaction. (
  • Since many legume lectins trigger harmful local and systemic reactions after their binding to the mucosal surface, these molecules are generally considered anti-nutritive and/or toxic substances. (
  • Most plants do not want to be eaten, so having these damaging molecules may discourage animals from eating them in large amounts. (
  • Peumans, W.J. and Van Damme, E.J.M. (1995) Lectins as Plant Defense Proteins. (
  • In plants, the function of lectins is less clear but some lectins are thought to be plant defense proteins, to protect against pathogens and insects. (
  • However, much more needs to be known about which lectins are harmful and the effects of dose and duration of consumption. (
  • We purify and characterize lectins from different plants and crops aiming to define which ones may be harmless, and which not. (
  • The objective of this study was to isolate and characterize lectin activity in Texas Live Oak ( Quercus fusiformis ). (
  • The further additional experiment needs to purify and characterize the bioactive lectin components from the potent sample which is responsible for pro-apoptotic, anti-angiogenic activity and mechanism involved. (
  • Through genetic mapping, resequencing and molecular validation, we demonstrate that a G-type lectin receptor-like kinase (lecRLK) mediates the symbiotic interaction between Populus and the ectomycorrhizal fungus Laccaria bicolor . (

  • She told NBC's the Today show that the weight loss is from a diet low in lectins that has helped her manage an autoimmune disorder. (
  • And despite Clarkson's experience - which is complicated by her autoimmune disorder - avoiding lectins isn't a sure path to shedding pounds. (
  • This is how lectins may increase the risk of autoimmune diseases. (
  • Because of its affinity for mucin, lectin-mediated vaccine delivery seems to be a promising concept in the design of mucosal immunization via oral route of administration. (
  • Two lectins obtained from different lentil cultivars, unlike other lectins, had a relatively high affinity for melecitose, N-acetyl-D-glucosamine, L-sorbose, and sucrose. (
