RL Submitted (MAR-2008) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Promotes mitochondrial protein synthesis. May act as a
CC fidelity factor of the translation reaction, by catalyzing a one-codon
CC backward translocation of tRNAs on improperly translocated ribosomes.
CC Binds to mitochondrial ribosomes in a GTP-dependent manner.
CC {ECO:0000255|HAMAP-Rule:MF_03137}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + H2O = GDP + H(+) + phosphate; Xref=Rhea:RHEA:19669,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:37565,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58189; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_03137};
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_03137}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_03137}; Matrix side {ECO:0000255|HAMAP-Rule:MF_03137}.
CC -!- MISCELLANEOUS: This protein may be expected to contain an N-terminal
CC transit peptide but none has been predicted. {ECO:0000255|HAMAP-
CC Rule:MF_03137}.
CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC superfamily. Classic translation factor GTPase family. LepA subfamily.
CC {ECO:0000305}.
