Mitochondrial RNase P complex
mitochondrial rnase p complex
Metazoans have two RNase P enzymes: a nuclear RNA-based RNase P and a mitochondrial PRORP (protein-only RNase P). Human mitochondrial RNase P consists of three subunits and lacks an RNA component. RNase P enzymes are metal ion-dependent endonucleases: hydrolases that catalyze site-specific phosphodiester bond hydrolysis primarily within pre-tRNA.
