GTPases (singular GTPase) are a large family of hydrolase enzymes that can bind and hydrolyze guanosine triphosphate (GTP). The GTP binding and hydrolysis takes place in the highly conserved G domain common to all GTPases. ==Functions== GTPases play an important role in: == Mechanism == The hydrolysis of the γ phosphate of GTP into guanosine diph...
