FIG. 4. Comparison of the Rac1b structures with Rac1. Ribbon representation of Rac1b·GDP (purple) and Rac1b·GppNHp (red) were superimposed on the structure of Rac1·GppNHp (brown) (17). The switch II region of Rac1 is highlighted in orange. The nucleotide (GppNHp of Rac1b) and the Mg2+ ion are shown as ball-and-stick.
