RNASE P PROTEIN FROM BACILLUS SUBTILIS
Overview
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.
About this Structure
1A6F is a Single protein structure of sequence from Bacillus subtilis with and as ligands. Active as Ribonuclease P, with EC number 3.1.26.5 Full crystallographic information is available from OCA.
