Group II Introns are small segments of DNA that reside in the chromosome of bacteria or the organelles of primitive eukaryotes. These elements have some very interesting properties. First, they are retrotransposons that can move from one location to a new location in DNA via a reverse transcription mechanism. Second, they form a large ribozyme that mediates self-splicing of the intron from pre-mRNA. A Group II Intron type protein with similarity to reverse transcriptase was discovered in the thermophilic bacterium Geobacillus stearothermophilus strain 10 (Vellore et al., 2004, Appl. Environ. Microbiol. 70: 7140-7147). Numerous copies of the intron, …
