Structural Prediction and Characterization of (ConGF) Lectin Complexed with MMP1: Unveiling the Antiglioma Potential of Legume Lectins.

A glioblastoma (GBM) is a highly malignant primary brain tumor with a poor prognosis because of its invasiveness and high resistance to current therapies. In GBMs, abnormal glycosylation patterns are associated with malignancy, which allows for the use of lectins as tools for recognition and therapy. More specifically, lectins can interact with glycan structures found on the malignant cell surface.

Structural analysis of Dioclea lasiocarpa lectin: A C6 cells apoptosis-inducing protein.

Lectins are multidomain proteins that specifically recognize various carbohydrates. The structural characterization of these molecules is crucial in understanding their function and activity in systems and organisms. Most cancer cells exhibit changes in glycosylation patterns, and lectins may be able to recognize these changes.

Canavalia bonariensis lectin: Molecular bases of glycoconjugates interaction and antiglioma potential.

CaBo is a mannose/glucose-specific lectin purified from seeds of Canavalia bonariensis. In the present work, we report the CaBo crystal structure determined to atomic resolution in the presence of X-man, a specific ligand. Similar to the structural characteristics of other legume lectins, CaBo presented the jellyroll motif, a metal binding site occupied by calcium and manganese ions close to the carbohydrate-recognition domain (CRD).

Structural characterization of a lectin from Canavalia virosa seeds with inflammatory and cytotoxic activities.

A lectin from Canavalia virosa, Diocleinae subtribe, was purified by affinity chromatography with Sephadex G-50 matrix and named ConV. The primary structure of ConV was obtained by mass spectrometry and crystals were obtained by the vapor diffusion method at 293K and belonged to orthorhombic space group P222 with two molecules in its asymmetric unit. The structure obtained presented R and R of 18.
