WebThese proteins oscillate between their GTP- and GDP-bound states via regulated cycles of GTP hydrolysis and exchange of GDP for GTP. The exchange of GDP for GTP is accelerated by the GDP/GTP Exchange Factor (GEF), while hydrolase activity of the GTPase is stimulated by the GTPase-Activating Protein (GAP).
