Ribonuclease P (RNase P) catalyzes the maturation of the 5' end of tRNA precursors. Typically these enzymes are ribonucleoproteins with a conserved RNA component responsible for catalysis. However, protein-only RNase P (PRORP) enzymes process precursor tRNAs in human mitochondria and in all tRNA-using compartments of Arabidopsis thaliana ...
