A comparative database of group I intron structures.
We have created a database of comparatively derived group I intron secondary structure diagrams. This collection currently contains a broad sampling of phylogenetically and structurally similar and diverse structures from over 200 publicly available intron sequences. As more group I introns are sequenced and added to the database, we anticipate minor refinements in these secondary structure dia...
متن کاملGISSD: Group I Intron Sequence and Structure Database
Group I Intron Sequence and Structure Database (GISSD) is a specialized and comprehensive database for group I introns, focusing on the integration of useful group I intron information from available databases and providing de novo data that is essential for understanding these introns at a systematic level. This database presents 1789 complete intron records, including the nucleotide sequence ...
متن کاملA group I intron riboswitch.
Riboswitches are mRNA-based elements that regulate gene expression via binding of a specific ligand. Breaker and coworkers have now discovered a novel type of regulatory RNA motif that acts by c-di-GMP-dependent control of a self-splicing group I intron ribozyme (Lee et al., 2010).
متن کاملModular engineering of a Group I intron ribozyme.
All Group I intron ribozymes contain a conserved core region consisting of two helical domains, P4-P6 and P3-P7. Recent studies have demonstrated that the elements required for catalysis are concentrated in the P3-P7 domain. We carried out in vitro selection experiments by using three newly constructed libraries on a variant of the T4 td Group I ribozyme containing only a P3-P7 domain in its co...
متن کاملExplosive invasion of plant mitochondria by a group I intron.
Group I introns are mobile, self-splicing genetic elements found principally in organellar genomes and nuclear rRNA genes. The only group I intron known from mitochondrial genomes of vascular plants is located in the cox1 gene of Peperomia, where it is thought to have been recently acquired by lateral transfer from a fungal donor. Southern-blot surveys of 335 diverse genera of land plants now s...
