    RNase P is the only endonuclease responsible for processing the 5' end of transfer RNA by cleaving a precursor and leading to tRNA maturation. It contains an RNA component and a protein component and has been identified in all organisms. It was one of the first catalytic RNAs identified and the first that acts as a multiple-turnover enzyme in vivo. RNase P and the ribosome are so far the only two ribozymes known to be conserved in all kingdoms of life. The RNA component of bacterial RNase P can catalyse pre-tRNA cleavage in the absence of the RNase P protein in vitro and consists of two domains: a specificity domain and a catalytic domain. Here we report a 3.15-A resolution crystal structure of the 154-nucleotide specificity domain of Bacillus subtilis RNase P. The structure reveals the architecture of this domain, the interactions that maintain the overall fold of the molecule, a large non-helical but well-structured module that is conserved in all RNase P RNA, and the regions that are involved in interactions with the substrate.
