Structural implications of novel diversity in eucaryal RNase P RNA.

ABSTRACT: Previous eucaryotic RNase P RNA secondary structural models have been based on limited diversity, representing only two of the approximately 30 phylogenetic kingdoms of the domain Eucarya. To elucidate a more generally applicable structure, we used biochemical, bioinformatic, and molecular approaches to obtain RNase P RNA sequences from diverse organisms including representatives of six additional kingdoms of eucaryotes. Novel sequences were from acanthamoeba (Acathamoeba castellanii, Balamuthia mandrillaris, Filamoeba nolandi), animals (Caenorhabditis elegans, Drosophila melanogaster), alveolates (Theileria annulata, Babesia bovis), conosids (Dictyostelium discoideum, Physarum polycephalum), trichomonads (Trichomonas vaginalis), microsporidia (Encephalitozoon cuniculi), and diplomonads (G
