Retrohoming of a Mobile Group II Intron in Human Cells Suggests How Eukaryotes Limit Group II Intron Proliferation. [PDF]
PLoS Genetics, 2015 Mobile bacterial group II introns are evolutionary ancestors of spliceosomal introns and retroelements in eukaryotes. They consist of an autocatalytic intron RNA (a "ribozyme") and an intron-encoded reverse transcriptase, which function together to ...

Group-II intron splicing factors in higher-plants mitochondria [PDF]
Frontiers in Plant Science, 2014 Group-II introns are large catalytic RNAs (ribozymes) which are found in bacteria and organellar genomes of several lower eukaryotes, but are particularly prevalent within the mitochondrial genomes (mtDNA) in plants, where they reside in numerous ...

Group II intron inhibits conjugative relaxase expression in bacteria by mRNA targeting [PDF]
eLife, 2018 Group II introns are mobile ribozymes that are rare in bacterial genomes, often cohabiting with various mobile elements, and seldom interrupting housekeeping genes. What accounts for this distribution has not been well understood.

Database for mobile group II introns [PDF]
Nucleic Acids Research, 2003 Group II introns are self-splicing RNAs and retroelements found in bacteria and lower eukaryotic organelles. During the past several years, they have been uncovered in surprising numbers in bacteria due to the genome sequencing projects; however, most of the newly sequenced introns are not correctly identified.

A Glimpse of the Catalytic Core of a Group II Intron [PDF]
Structure, 2002 A paper in a recent issue of Science describes the first high-resolution structure of part of the catalytic core of a group II intron that will allow more detailed comparisons between the excision of introns by self-splicing group II introns and by nuclear pre-mRNA introns.

Group II introns break new boundaries: presence in a bilaterian's genome. [PDF]
PLoS ONE, 2008 Group II introns are ribozymes, removing themselves from their primary transcripts, as well as mobile genetic elements, transposing via an RNA intermediate, and are thought to be the ancestors of spliceosomal introns. Although common in bacteria and most

Group II Introns: Highly Structured yet Dynamic
CHIMIA, 2023 RNA splicing, the removal of introns and ligation of exons, is a crucial process during mRNA maturation. Group II introns are large ribozymes that self-catalyze their splicing, as well as their transposition.

Identification of a family of group II introns encoding LAGLIDADG ORFs typical of group I introns [PDF]
RNA, 2002 Group I and group II introns are unrelated classes of introns that each encode proteins that facilitate intron splicing and intron mobility. Here we describe a new subfamily of nine introns in fungi that are group II introns but encode LAGLIDADG ORFs typical of group I introns. The introns have fairly standard group IIB1 RNA structures and are inserted

Phylogenetic relationships among group II intron ORFs [PDF]
Nucleic Acids Research, 2001 Group II introns are widely believed to have been ancestors of spliceosomal introns, yet little is known about their own evolutionary history. In order to address the evolution of mobile group II introns, we have compiled 71 open reading frames (ORFs) related to group II intron reverse transcriptases and subjected their derived amino acid sequences to ...
