  • Title: A self-splicing intron in the small subunit rRNA gene of Pneumocystis carinii.
    Author: Sogin ML, Edman JC.
    Journal: Nucleic Acids Res; 1989 Jul 11; 17(13):5349-59. PubMed ID: 2788266.
    Abstract:
    The coding region for the Pneumocystis carinii small subunit rRNA (16S-like rRNA) contains 390 extra base pairs in a region that is highly conserved in other eukaryotic rRNA genes. The sequence has all the elements characteristic of group I self-splicing introns and interrupts the phylogenetically conserved helix proximal to the 3' terminus of the 16S-like rRNA. In vitro transcripts containing the putative group I intron were capable of undergoing a "self-splicing" reaction which required the presence of guanine nucleotide.
