| - | [ | + | [https://www.uniprot.org/uniprot/RNPA_BACSU RNPA_BACSU] RNaseP catalyzes the removal of the 5'-leader sequence from pre-tRNA to produce the mature 5'-terminus. It can also cleave other RNA substrates such as 4.5S RNA. The protein component plays an auxiliary but essential role in vivo by binding to the 5'-leader sequence and broadening the substrate specificity of the ribozyme. |

| - | The crystal structure of Bacillus subtilis ribonuclease P protein is reported at 2.6 angstroms resolution. This protein binds to ribonuclease P RNA to form a ribonucleoprotein holoenzyme with optimal catalytic activity. Mutagenesis and biochemical data indicate that an unusual left-handed betaalphabeta crossover connection and a large central cleft in the protein form conserved RNA binding sites; a metal binding loop may comprise a third RNA binding site. The unusual topology is partly shared with ribosomal protein S5 and the ribosomal translocase elongation factor G, which suggests evolution from a common RNA binding ancestor in the primordial translational apparatus. | ||
