Ribonuclease P (RNase P) is the enzyme responsible for endonucleolytically separating the 5'-leader sequence from precursor tRNA molecules. In bacteria, and in the nuclei and mitochondria of all eukaryotes studied so far, RNase P contains an RNA subunit which is necessary for activity in vitro and in vivo. In contrast, we showed earlier that partially-purified RNase P from spinach chloroplasts had physical properties inconsistent with the presence of any RNA. We now report that the properties… CONTINUE READING
