Abstract:

The GTP/GDP conformational switch of members of the rab family of ras-related GTP-ases control specific intracellular vesicle transport pathways. We report the crystallization of the late-endosomal rab protein rab7, in both GTP and GDP conformations. X-ray data from crystals of rab7(1-207) GppNHp (i.e., intact rab7, without C-terminal bound lipid, complexed with a non-hydrolysable GTP analog), rab7(1-197)GppNHp and rab7(1-197)GDP were collected to 1.9A (0 degree C), 1.76A (100 degrees K) and 1.75A (100 degrees K) respectively. Rab7-GDP crystals diffract to at least 1.35A.
