Structure of Banana lectin-alpha-D-mannose complexStructure of Banana lectin-alpha-D-mannose complex
Structural highlights
Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe three crystal structures reported here provide details of the interactions of mannose and the mannosyl-alpha-1,3-mannose component of a pentamannose with banana lectin and evidence for the binding of glucosyl-alpha-1,2-glucose to the lectin. The known structures involving the lectin include a complex with glucosyl-beta-1,3-glucose. Modelling studies on the three disaccharide complexes with the reducing end and the non-reducing end at the primary binding site are also provided here. The results of the X-ray and modelling studies show that the disaccharides with an alpha-1,3 linkage prefer to have the non-reducing end at the primary binding site while the reducing end is preferred at the site when the linkage is beta-1,3 in mannose/glucose specific beta-prism I fold lectins. In the corresponding galactose-specific lectins, however, alpha-1,3 linked disaccharides cannot bind the lectin with the non-reducing end at the primary binding site on account of steric clashes with an aromatic residue which occurs only when the lectin is galactose-specific. Molecular dynamics simulations based on the known structures involving banana lectin enrich the information on lectin-carbohydrate interactions obtained from crystal structures. They demonstrate that conformational selection as well as induced fit operate when carbohydrates bind to banana lectin. Influence of glycosidic linkage on the nature of carbohydrate binding in {beta}-prism I fold lectins.
