New crystal forms of Diocleinae lectins in the presence of different dimannosides [PDF]

Acta Crystallographica Section F: Structural Biology Communications, 2006
Studying the interactions between lectins and sugars is important in order to explain the differences observed in the biological activities presented by the highly similar proteins of the Diocleinae subtribe. Here, the crystallization and preliminary X-ray data of Canavalia gladiata lectin (CGL) and C.

The carbohydrate-binding specificity and molecular modelling of Canavalia maritima and Dioclea grandiflora lectins

Memorias do Instituto Oswaldo Cruz, 1996
The carbohydrate-binding specificity of lectins from the seeds of Canavalia maritima and Dioclea grandiflora was studied by hapten-inhibition of haemagglutination using various sugars and sugar derivatives as inhibitors, including N-acetylneuraminic acid

The effect of Cratylia floribunda lectin on renal hemodynamics and ion transport

Brazilian Journal of Pharmaceutical Sciences, 2015
Lectins have been described as glycoproteins that reversibly and specifically bind to carbohydrates. Legume lectins isolated from the subtribe Diocleinae (Canavalia, Dioclea andCratylia) are structurally homologous with respect to their primary ...

Caracterização molecular de acessos de Cratylia argentea e sua relação filogenética com outras leguminosas Molecular characterization of Cratylia argentea accessions and its phylogenetic relationship with other legumes

Pesquisa Agropecuária Brasileira, 2010
O objetivo deste trabalho foi realizar a caracterização molecular de 11 acessos de Cratylia argentea, com base no sequenciamento da região ITS (ITS1/5,8S/ITS2), bem como o estabelecimento de suas relações filogenéticas com outras leguminosas. As relações

Carbohydrate/glycan-binding specificity of legume lectins in respect to their proposed biological functions

Brazilian Archives of Biology and Technology, 2000
The lectins, proteins which specifically recognize carbohydrate moieties, have been extensively studied in many biochemical and structural aspects in order to establish the molecular basis of this non-catalytic event.

Insights into the structural basis of the pH-dependent dimer–tetramer equilibrium through crystallographic analysis of recombinantDiocleinaelectins [PDF]

Biochemical Journal, 2007
The structural ground underlying the pH-dependency of the dimer–tetramer transition of Diocleinae lectins was investigated by equilibrium sedimentation and X-ray crystal structure determination of wild-type and site-directed mutants of recombinant lectins.

Revisiting proteus: Do Minor Changes in Lectin Structure Matter in Biological Activity? Lessons from and Potential Biotechnological Uses of the Diocleinae Subtribe Lectins [PDF]

Current Protein & Peptide Science, 2001
Significant differences in function have been observed among lectins structurally similar to concanavalin A, but their high homology with this widely used lectin has kept them in obscurity. The observation of large differences in the potency of many of these Diocleinae lectins as stimulators of Interferon-g production by human peripheral blood ...

A Diocleinae type II lectin from Dioclea lasiophylla Mart. Ex Benth seeds specific to α-lactose/GalNAc

Process Biochemistry, 2020
Abstract A type II lectin, designated as DlyL2, was purified from Dioclea lasiophylla Mart. ex Benth seeds and some of its physicochemical properties determined. The lectin demonstrated specificity for α-lactose and N-acetyl- d -galactosamine and was able to interact with porcine stomach mucin.
