Figure 2

The three dimensional crystal structure of holo-RBP. The human holo-RBP structure (PDB ID 1BRP) was rendered using Pymol (http://www.pymol.org/). The structure shows the eight stranded antiparallel 3-sheet folded over itself to form a 3-barrel. Retinol (white) is encapsulated by the barrel with the 3-ionone ring buried in the binding pocket and the alcohol group is at the protein surface.
