Abstract

Arf1 is a small G protein involved in vesicular trafficking, and although it is only distantly related to Ras, it adopts a similar three-dimensional structure. In the present work, we study Arf1 bound to GDP and GTP and its interactions with one of its guanosine nucleotide exchange factors, ARNO-Sec7. The (31)P NMR spectra of Arf1.GDP.Mg(2+) and Arf1.GTP.Mg(2+) share the general features typical ...
