lathyrus niger/carbohydrate

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

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

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

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,

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 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,

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

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

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

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

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

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

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

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

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
