Ribonuclease P
Definition:
EC Tree > 3 Hydrolases > 3.1 Acting on ester bonds > 3.1.26 Endoribonucleases producing 5'-phosphomonoesters > 3.1.26.5 ribonuclease P
Ribonuclease P is the tRNA 5'-maturation ribozyme. It cleaves the 5'-leader from pre-tRNA, generating mature 5'-termini; most forms contain a catalytic RNA plus protein subunits, but human mitochondrial and spinach chloroplast forms are protein-only. It occurs in viruses and cellular organisms.
