GTPases are a large family of hydrolase enzymes that bind to the nucleotide guanosine triphosphate (GTP) and hydrolyze it to guanosine diphosphate (GDP). The GTP binding and hydrolysis takes place in the highly conserved P-loop "G domain", a protein domain common to many GTPases. See more GTPases function as molecular switches or timers in many fundamental cellular processes. Examples of these roles include: • Signal transduction in response to activation of cell … See more In most GTPases, the specificity for the base guanine versus other nucleotides is imparted by the base-recognition motif, which has the … See more • G protein-coupled receptors • Growth factor receptor • Septins See more Hydrolysis of GTP bound to an (active) G domain-GTPase leads to deactivation of the signaling/timer function of the enzyme. The hydrolysis of the third (γ) phosphate of GTP to create guanosine diphosphate (GDP) and Pi, inorganic phosphate, occurs by the SN2 … See more While tubulin and related structural proteins also bind and hydrolyze GTP as part of their function to form intracellular tubules, these proteins utilize a distinct tubulin domain that … See more • GTPase at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • MBInfo - RhoGTPases Archived 2013-03-31 at the See more WebGTPase is an enzyme that belongs to the immunity-associated protein family (GIMAPs). …
