Structural conventions for group I introns.
Conventions for nomenclature of structural elements and a standard secondary structure representation for group I introns have been established by workers in the field. These conventions are designed to facilitate effective communication of information concerning the structure and function of these self-splicing introns.
متن کاملStructural conservation among three homologous introns of bacteriophage T4 and the group I introns of eukaryotes.
Three group I introns of bacteriophage T4 have been compared with respect to their sequence and structural properties. The introns include the td intervening sequence, as well as the two newly described introns in the nrdB and sunY genes of T4. The T4 introns are very closely related, containing phylogenetically conserved sequence elements that allow them to be folded into a core structure that...
متن کاملThe natural history of group I introns.
There are four major classes of introns: self-splicing group I and group II introns, tRNA and/or archaeal introns and spliceosomal introns in nuclear pre-mRNA. Group I introns are widely distributed in protists, bacteria and bacteriophages. Group II introns are found in fungal and land plant mitochondria, algal plastids, bacteria and Archaea. Group II and spliceosomal introns share a common spl...
متن کاملGroup I introns and RNA folding.
Before the discovery of catalytic RNA, tRNA molecules were the most studied RNA molecules for understanding RNA folding. Afterwards, group I introns, because of their stability and the fact that structural folding could be monitored by following their catalytic activity, became the molecule of choice for studying RNA architecture and folding. A major advantage of group I introns for studying th...
متن کاملIdentification of a family of group II introns encoding LAGLIDADG ORFs typical of group I introns.
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 into three different sites in SSU and LSU ...
