This domain is found in Mitochondrial dynamics protein MID51 from humans and similar proteins predominantly found in vertebrates. MID51 promotes the recruitment and association of the fission mediator dynamin-related protein 1 (DNM1L) to the mitochondrial surface to drive mitochondrial fission. This entry represents the C-terminal domain of this protein, which adopts a nucleotidyltransferase fold with a mixed alpha-beta topology configured into two lobes separated by a deep cleft [1-4].
