Group II introns are self-splicing ribozymes that share a reaction mechanism and a common
ancestor with the eukaryotic spliceosome, thereby providing a model system for …

Group II introns are ubiquitous self-splicing ribozymes and retrotransposable elements
evolutionarily and chemically related to the eukaryotic spliceosome, with potential …

Group II introns are mobile genetic elements that self-splice and retrotranspose into DNA
and RNA. They are considered evolutionary ancestors of the spliceosome, the …

The identical reaction pathway executed by the spliceosome and self-splicing group II intron
ribozymes has prompted the idea that both may be derived from a common molecular …

Group II introns are large, autocatalytic ribozymes that catalyze RNA splicing and
retrotransposition. Splicing by group II introns plays a major role in the metabolism of plants …

Group II introns are one of the largest self-splicing ribozymes found in organellar genomes
of various eukaryotes such as fungi, plants and some animals as well as in bacterial …

Intron splicing is a fundamental biological process whereby noncoding sequences are
removed from precursor RNAs. Recent work has provided new insights into the structural …

The self-splicing intron ribozymes have been regarded as primitive forms of the splicing
machinery for eukaryotic pre-mRNAs. The splicing activity of group I self-splicing introns is …

Group II introns are self-splicing catalytic RNAs that are thought to be ancestral to the
spliceosome. Here we report the 3.65-Å crystal structure of the group II intron from …

The group I intron has served as a model for RNA catalysis since its discovery 25 years ago.
Four recently determined high-resolution crystal structures complement extensive …
