Modulation of a lectin insecticidal activity by carbohydrates.

Only registered users can translate articles

Lectins from plants present an insecticidal activity most probably through their carbohydrate binding properties; as a consequence, their toxicity should vary with the presence of a competitive sugar in the ingested food. In order to test this hypothesis, we performed competition experiments between

Molecular modelling of protein-carbohydrate interactions. Understanding the specificities of two legume lectins towards oligosaccharides.

Only registered users can translate articles

By means of a series of new molecular modelling tools, the conformational behaviour of mannose-containing di- and trisaccharides bound to either concanavalin A or Lathyrus ochrus isolectin I (LOLI) has been assessed. Tools for estimating and analysing either the 'rigid' or the 'relaxed' potential

Molecular dynamics simulations of oligosaccharides and their conformation in the crystal structure of lectin-carbohydrate complex: importance of the torsion angle psi for the orientation of alpha 1,6-arm.

The conformation of the heptasaccharide Man-alpha 1,6-(Man-alpha 1,3)(Xyl-beta 1,2)-Man-beta 1,4-GlcNAc2-beta 1,4-(L- Fuc-alpha 1,3)-GlcNAc1, the carbohydrate moiety of Erythrina corallodendron lectin (EcorL), the hexasaccharide Man-alpha 1,6-(Man-alpha 1,3) (GlcNAc-beta 1,4)-Man-beta

Architecture of the sugar binding sites in carbohydrate binding proteins--a computer modeling study.

Only registered users can translate articles

Different sugars, Gal, GalNAc and Man were docked at the monosaccharide binding sites of Erythrina corallodenron (EcorL), peanut lectin (PNA), Lathyrus ochrus (LOLI), and pea lectin (PSL). To study the lectin-carbohydrate interactions, in the complexes, the hydroxymethyl group in Man and Gal favors,

Plant root carbohydrates affect growth behaviour of endophytic microfungi.

Abstract Peucedanum alsaticum and Peucedanum cervaria represent characteristic umbellifers (Apiaceae) of calcareous grasslands in Central and Eastern Europe. Both accumulate glucose, fructose, mannitol and sucrose as dominant carbohydrates in their roots. The objective of the study was to determine

The monosaccharide binding site of lentil lectin: an X-ray and molecular modelling study.

Only registered users can translate articles

The X-ray crystal structure of lentil lectin in complex with alpha-D-glucopyranose has been determined by molecular replacement and refined to an R-value of 0.20 at 3.0 A resolution. The glucose interacts with the protein in a manner similar to that found in the mannose complexes of concanavalin A,

X-ray crystal structure of a pea lectin-trimannoside complex at 2.6 A resolution.

Only registered users can translate articles

The x-ray crystal structure of pea lectin, in complex with a methyl glycoside of the N-linked-type oligosaccharide trimannosyl core, methyl 3,6-di-O-(alpha-D-mannopyranosyl)-alpha-D-mannopyranoside, has been solved by molecular replacement and refined at 2.6-A resolution. The R factor is 0.183 for

Studies on lectins. XLIX. The use of glycosyl derivatives of Dextran T-500 for affinity electrophoresis of lectins.

Only registered users can translate articles

p-Aminophenyl glycosides and glycosylamines were coupled to periodate oxidized Dextran T-500 either directly or through an epsilon-aminocaproic acid spacer. The new glycosylated derivatives of dextran specifically precipitate lectins having the appropriate carbohydrate specificity, and thus were

Variety-specific nutrient acquisition and dehydration-induced proteomic landscape of grasspea (Lathyrus sativus L.).

Only registered users can translate articles

Grasspea, a stress-resilient pulse crop, has largely remained outside the realm of phytochemical and functional genomics analyses despite its high nutritional significance. To unravel the intervarietal variability in nutrient acquisition of grasspea, we conducted a series of physicochemical

Metabolomics Approach To Understand Mechanisms of β-N-Oxalyl-l-α,β-diaminopropionic Acid (β-ODAP) Biosynthesis in Grass Pea (Lathyrus sativus L.).

Only registered users can translate articles

A study was performed to identify metabolic processes associated with β-ODAP synthesis in grass pea using a metabolomics approach. GC-MS metabolomics was performed on seedlings at 2, 6, and 25 days after sowing. A total of 141 metabolites were detected among the three time points representing much

Structures of a legume lectin complexed with the human lactotransferrin N2 fragment, and with an isolated biantennary glycopeptide: role of the fucose moiety.

Only registered users can translate articles

BACKGROUND Lectins mediate cell-cell interactions by specifically recognizing oligosaccharide chains. Legume lectins serve as mediators for the symbiotic interactions between plants and nitrogen-fixing microorganisms, an important process in the nitrogen cycle. Lectins from the Viciae tribe have a

Valorization of traditional foods: nutritional and bioactive properties of Cicer arietinum L. and Lathyrus sativus L. pulses.

Only registered users can translate articles

BACKGROUND The use of traditional foods can enrich our diet, perpetuating important elements of local knowledge and cultural inheritance. Raw, soaked and cooked samples of two Fabaceae species (Cicer arietinum L. and Lathyrus sativus L.) were characterized regarding nutritional and bioactive

Mitogenic properties of structurally related Lathyrus lectins.

Only registered users can translate articles

The mitogenic properties of ten phylogenetically related Lathyrus lectins have been studied. Despite a close structural resemblance and similar carbohydrate specificities, the lectins exhibited significant differences in their ability to induce cell proliferation of human lymphocytes. The

Identification of L-Bornesitol and Changes in Its Content during Flower Bud Development in Sweet Pea (Lathyrus odoratus L.).

Only registered users can translate articles

An unidentified carbohydrate was isolated from sweet pea (Lathyrus odoratus L. cv. Diana) petals using HPLC. The isolated compound was identified as L-1-O-methyl-myo-inositol, called L-bornesitol, using (1)H-NMR, (13)C-NMR, and CI-MS. L-Bornesitol was distributed in all organs at high

Evaluation of several holding solutions for prolonging vase-life and keeping quality of cut sweet pea flowers (Lathyrus odoratus L.).

Only registered users can translate articles

Cut spikes of sweet pea (Lathyrus odoratus L.) were kept in 2% sucrose, 200 ppm 8-hydroxyquinoline sulfate (8-HQS), pulsing treatment with 200 ppm 8-HQS in combination with 2% sucrose for 12 h, pulsing the spikes with 0.2 mM silver thiosulfate (STS) for 1 h and pulsing with 0.2 mM STS for 1 h
