WebRibonuclease P (RNase P) catalyzes the cleavage of leader sequences from precursor tRNA (pre-tRNA). Typically, these enzymes are ribonucleic protein complexes that are found in all domains of life. However, a new class of RNase P has been discovered that is composed entirely of protein, termed protein-only RNase P (PRORP). WebThe active site contains parts of the phosphate backbone, at least two metal ions, and a universally conserved U residue. This detailed picture of the RNase P-substrate …
