摘要：

The recent availability of the full Saccharomyces cerevisiae genome sequence offers a first opportunity to analyze the composition, function and evolution of GTPases in the ras-p21 superfamily, This superfamily in yeast is composed of 29 proteins divided into five families: ras with four sequences implicated in cell signalling; rho, six genes related to the cell shape machinery; ypt-rab, ten proteins with different roles in intracellular trafficking; arf-sar, seven proteins related to vesicular trafficking in secretory pathways; and ran, two proteins acting as components of the nuclear transport system. The superfamily covers a wide range of cellular functions from signalling to intracellular trafficking, while conserving the structural framework and a common mechanism of GTP hydrolysis, (C) 1998 Federation of European Biochemical Societies.
