Tubulin GTPase (EC 3.6.5.6) is an enzyme with systematic name GTP phosphohydrolase (microtubule-releasing).[1][2][3] This enzyme catalyses the following chemical reaction

GTP + H2O [math]\displaystyle{ \rightleftharpoons }[/math] GDP + phosphate

This enzyme participates in tubulin folding and division plane formation.
