Rab/Ypt guanosine triphosphatases (GTPases) represent a family of key, membrane traffic regulators in eukaryotic cells whose function is governed, by the guanosine diphosphate (GDP) dissociation inhibitor (RabGDI). Using, a combination of chemical synthesis and protein engineering, we generated, and crystallized the monoprenylated Ypt1:RabGDI complex. The structure of, the complex was solved to 1.5 angstrom resolution and provides a, structural basis for the ability of RabGDI to inhibit the release of, nucleotide by Rab proteins. Isoprenoid binding requires a conformational, change that opens a cavity in the hydrophobic core of its domain II., Analysis of the structure provides a molecular basis for understanding a, RabGDI mutant that causes mental retardation in humans.

Rab/Ypt guanosine triphosphatases (GTPases) represent a family of key membrane traffic regulators in eukaryotic cells whose function is governed by the guanosine diphosphate (GDP) dissociation inhibitor (RabGDI). Using a combination of chemical synthesis and protein engineering, we generated and crystallized the monoprenylated Ypt1:RabGDI complex. The structure of the complex was solved to 1.5 angstrom resolution and provides a structural basis for the ability of RabGDI to inhibit the release of nucleotide by Rab proteins. Isoprenoid binding requires a conformational change that opens a cavity in the hydrophobic core of its domain II. Analysis of the structure provides a molecular basis for understanding a RabGDI mutant that causes mental retardation in humans.
