Ribonuclease P (RNase P) is the endonuclease responsible for the removal of 5' leader sequences from tRNA precursors. The crystal structure of an archaeal RNase P protein, Ph1771p (residues 36-127) from hyperthermophilic archaeon Pyrococcus horikoshii OT3 was determined at 2.0 A resolution by X-ray crystallography. The structure is composed of four helices (alpha1-alpha4) and a six-stranded antiparallel beta-sheet (beta1-beta6) with a protruding beta-strand (beta7) at the C-terminal region.
