Crystal Structure of the phosphorolytic exoribonuclease RNase PH from Bacillus subtilis
Overview
RNase PH is a member of the family of phosphorolytic 3' --> 5' exoribonucleases that also includes polynucleotide phosphorylase (PNPase). RNase PH is involved in the maturation of tRNA precursors and especially important for removal of nucleotide residues near the CCA acceptor end of the mature tRNAs. Wild-type and triple mutant R68Q-R73Q-R76Q RNase PH from Bacillus subtilis have been crystallized and the structures determined by X-ray diffraction to medium resolution. Wild-type and triple mutant RNase PH crystallize as a hexamer and dimer, respectively. The structures contain a rare left-handed beta alpha beta-motif in the N-terminal portion of the protein. This motif has also been identified in other enzymes involved in RNA metabolism. The RNase PH structure and active site can, despite low sequence similarity, be overlayed with the N-terminal core of the structure and active site of Streptomyces antibioticus PNPase. The surface of the RNase PH dimer fit the shape of a tRNA molecule.
