    • Short-term sequence evolution and vertical inheritance of the Naegleria twin-ribozyme group I intron 

      Wikmark, Odd-Gunnar; De Jonckheere, Johan F.; Einvik, Christer; Johansen, Steinar D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-05-02)
      Background Ribosomal DNA of several species of the free-living Naegleria amoeba harbors an optional group I intron within the nuclear small subunit ribosomal RNA gene. The intron (Nae.S516) has a complex organization of two ribozyme domains (NaGIR1 and NaGIR2) and a homing endonuclease gene (NaHEG). NaGIR2 is responsible for intron excision, exon ligation, and full-length intron RNA circularization, ...
