Group II introns: structure, folding and splicing mechanism

bchm, 2007
Abstract Group II introns are large autocatalytic RNAs found in organellar genomes of plants and lower eukaryotes, as well as in some bacterial genomes. Interestingly, these ribozymes share characteristic traits with both spliceosomal introns and non-LTR retrotransposons and may have a common evolutionary ancestor.

Group II introns: versatile ribozymes and retroelements

WIREs RNA, 2016
Group II introns are catalytic RNAs (ribozymes) and retroelements found in the genomes of bacteria, archaebacteria, and organelles of some eukaryotes. The prototypical retroelement form consists of a structurally conserved RNA and a multidomain reverse transcriptase protein, which interact with each other to mediate splicing and mobility reactions.

Bacterial Group II Introns: Identification and Mobility Assay

2016
Group II introns are large catalytic RNAs and mobile retroelements that encode a reverse transcriptase. Here, we provide methods for their identification in bacterial genomes and further analysis of their splicing and mobility capacities.

Intron Biology, Focusing on Group II Introns, the Ancestors of Spliceosomal Introns

2015
Self-splicing group II introns are large ribozymes and mobile retroelements initially identified in the mitochondrial and chloroplast genomes of lower eukaryotes and plants and subsequently found in bacteria and archaea. Group II introns display structural, functional and mechanistic similarities to eukaryotic pre-mRNA nuclear introns, which may have ...

Group II and group III introns of twintrons: potential relationships with nuclear pre-mRNA introns

Trends in Biochemical Sciences, 1993
Two new and important features of introns have emerged from analysis of the Euglena gracilis chloroplast genome. One is a new class of introns, designated group III, that may be the closest contemporaries to nuclear pre-mRNA introns. The second is introns that are interrupted by other introns termed twintrons.

Group II Intron Thermophilic Reverse Transcriptases [PDF]

, 2011
A reverse transcription reaction allows the production of complementary DNA (cDNA) using an RNA template and relies on polymerases displaying reverse transcriptase (RT) activity. This process, with major applications in both research and in medical diagnostics, is often limited by the nature of the RTs available.

Group II introns in the bacterial world.

Molecular microbiology, 2001
Group II introns are large catalytic RNA molecules that act as mobile genetic elements. They were initially identified in the organelle genomes of lower eukaryotes and plants, and it has been suggested that they are the progenitors of nuclear spliceosomal introns.
