GTPases are a group of enzymes that catalyze hydrolysis of the γ phosphate bond in guanine triphosphate (GTP) to form guanine diphosphate (GDP). Mg2+ ions are essential for catalytic activity. GTPases, often coupled to G proteins, are essential in signal transduction.

GTPases are a group of enzymes that catalyze hydrolysis of the γ phosphate bond in guanine triphosphate (GTP) to form guanine diphosphate (GDP). Mg2+ is essential for catalytic activity. GTPases are often coupled to G proteins and have essential roles in signal transduction, protein synthesis and translocation, control of cell growth and differentiation and vesicular transport regulation.

There are six main groups of GTPases; heterotrimeric G protein GTPases (E.C., small monomeric GTPases (E.C., protein-synthesizing GTPases (E.C., signal-recognition-particle GTPase (E.C., dynamin GTPases (E.C. and tubulin GTPases (E.C.
