Figure 1

The structure of bovine retinol binding protein. A cartoon rendering of RBP (pdb code 1HBP) in which α-helices are shown as cylinders and β-strands as arrows. The conformational change that accompanies ligand binding is confined to amino acids 33-37;15 this region is illustrated in stick rendering (holo-protein, carbon white, nitrogen blue, oxygen red; apo protein (1HBQ), carbon pink, nitrogen blue, oxygen red). Retinol is shown in orange.
