Group II introns are ribozymes that catalyze a splicing reaction with the same chemical steps as spliceosome-mediated splicing. Many group II introns have lost the capacity to self-splice while ...

Thousands of introns have been localized to rRNA genes throughout the three domains of life. The consequences of the presence of either a spliced or an unspliced intron in a rRNA for ribosome assembly ...

Although general understanding of RNA tertiary structure is rapidly increasing, knowledge about group II intron architecture has grown slowly. This is unfortunate because group II introns are uniquely ...

Homing endonucleases are usually encoded within self-splicing introns or inteins, and are found in representatives of all three kingdoms 1,2. The endonuclease genes and their host intron or intein are ...
