Fig. 4. Superposition of Rab11 in different forms. The switch 1 and switch 2 regions are shown. The side chains of Arg-72 and Arg-74 in the switch 2 region are indicated by ball-and-stick models. GTP/GDP molecules also are presented as ball-and-stick models. The GDP-bound form (PDB ID code 1OIV) is blue, the GTP-bound free form (PDB ID code 1OIW) is green, and molecule A GTP-bound Rab11 in complex with FIP3-RBD is red, whereas molecule B is orange.
