Involved in cytokinesis. May hydrolyze GTP. GTP + H2O = GDP + H(+) + phosphate Expression begins during cell cycle progression, between 12 and 24 hours after germination. Reach a maximum around mid-log phase and disappear during the stationary phase. Produced cells are larger and a large amount of them contains more than 2 nuclei. Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family.
