GBL is an all beta-sheet protein[1]. Relevance GBL is used in affinity columns for capturing proteins which are glycosylated with Gal-β(1,3)-GalNac. Structural highlights The carbohydrate ligand binds to 3 loops[2]. in peanut galactose-binding lectin (PDB entry 1v6i). . . Water molecules shown as red spheres.
