Saxena S, Das HR, Das D, Biswas S., Homology based 3D–structure modeling of glucose specific Sesbania stem lectin, Onl J Bioinform., 9 (2):113-120, 2008. The lectins from legumes show a considerable sequence and structural homology but their differences in carbohydrate specificity make them unique for studying structure function relationships. 3D models of proteins were created to evaluate crystal structure and function relationships. The 3D model of Sesbania bispinosa stem lectin (STA) (Accession No.ABX59683.1) was vizualised using web server Geno3D. Stereochemical properties were analyzed using PROCHECK and generated models visualized with Rasmol 3D viewer and MolProbity for X-ray crystallography. This study describes computer generated molecular models for which crystal structures are not available.
