GBL is an all beta-sheet protein. 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. β-D-galactose/α-D-glucose binding site in peanut galactose-binding lectin (PDB entry 1v6i). Ca coordination site.
