Purification and primary structure determination of a galactose-specific lectin...
Silva, Helton Colares; Nagano, C. S.; Souza, Luis A.G.; Nascimento, K. S.; Isídro, Renato; Delatorre, Plínio; Rocha, Bruno Anderson Matias daVatairea guianensis seeds, a typical plant from the Brazilian Amazon region that belongs to the Dalbergieae tribe, possess a lectin that was isolated by precipitation with solid ammonium sulfate followed by guar gum affinity chromatography. This lectin was named VGL. The V. guianensis lectin strongly agglutinated rabbit erythrocytes and was inhibited by d-galactose and d-galactose-derived sugars, especially N-a...
Fine specificities of two lectins from Cymbosema roseum seeds: A lectin specifi...
Dam, Tarun Kanti; Cavada, B. S.; Nagano, C. S.; Rocha, Bruno Anderson Matias da; Benevides, R. G.; Nascimento, K. S.; Sousa, Luiz A.G. deThe legume species of Cymbosema roseum of Diocleinae subtribe produce at least two different seed lectins. The present study demonstrates that C. roseum lectin I (CRL I) binds with high affinity to the "core" trimannoside of N-linked oligosaccharides. Cymbosema roseum lectin II (CRL II), on the other hand, binds with high affinity to the blood group H trisaccharide (Fuc1,2Gal1-4GlcNAc-). Thermodynamic and hemag...
Structural basis for both pro- and anti-inflammatory response induced by mannos...
Rocha, Bruno Anderson Matias da; Delatorre, Plínio; Oliveira, Taianá Maia; Benevides, R. G.; Pires, Alana de Freitas; Sousa, Albertina A.S.Legume lectins, despite high sequence homology, express diverse biological activities that vary in potency and efficacy. In studies reported here, the mannose-specific lectin from Cymbosema roseum (CRLI), which binds N-glycoproteins, shows both pro-inflammatory effects when administered by local injection and anti-inflammatory effects when by systemic injection. Protein sequencing was obtained by Tandem Mass Sp...
