CC -!- FUNCTION: Mitochondrial GTPase that mediates the disassembly of
CC ribosomes from messenger RNA at the termination of mitochondrial
CC protein biosynthesis. Not involved in the GTP-dependent ribosomal
CC translocation step during translation elongation. {ECO:0000255|HAMAP-
CC Rule:MF_03059}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000255|HAMAP-Rule:MF_03059}.
CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC superfamily. Classic translation factor GTPase family. EF-G/EF-2
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_03059}.
