CC -!- FUNCTION: The natural substrate for this enzyme may be peptidyl-tRNAs
CC which drop off the ribosome during protein synthesis. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=an N-acyl-L-alpha-aminoacyl-tRNA + H2O = a tRNA + an N-acyl-L-
CC amino acid + H(+); Xref=Rhea:RHEA:54448, Rhea:RHEA-COMP:10123,
CC Rhea:RHEA-COMP:13883, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:59874, ChEBI:CHEBI:78442, ChEBI:CHEBI:138191;
CC EC=3.1.1.29;
CC -!- SUBUNIT: Monomer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000250}.
CC -!- PTM: Ubiquitinated by PRKN during mitophagy, leading to its degradation
CC and enhancement of mitophagy. Deubiquitinated by USP30.
CC {ECO:0000250|UniProtKB:Q9Y3E5}.
CC -!- SIMILARITY: Belongs to the PTH2 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAC26006.1; Type=Erroneous initiation; Evidence={ECO:0000305};
