GTPase 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: * Signal transduction at the intracellular domain of transmembrane receptors, including recognition of taste, smell and light. * Protein biosynthesis (a.k.a. translation) at the ribosome. * Control and differentiation during cell division. * Translocation of proteins through membranes. * Transport of vesicles within the cell. (GTPases control assembly of vesicle coats.)
