GO:0030678:   mitochondrial ribonuclease P complex
A ribonuclease P complex located in the mitochondrion of a eukaryotic cell, where it catalyzes the 5" endonucleolytic cleavage of precursor tRNAs to yield mature tRNAs. The subunit composition of mitochondrial ribonuclease P complexes varies between species, but the complex often contains a single RNA molecule and a single protein molecule.
