Term Information

Accession: GO:0000372
Name: Group I intron splicing
Ontology: biological_process
Synonyms: mRNA splicing
Alternate IDs: None
Definition: The splicing of Group I introns. This occurs by a ribozymic mechanism where the intron sequence forms a distinct 3D structure, characteristic of Group I introns and involved in determining the locations of the splice sites (there do not appear to be consensus splice site sequences) as well as having a role in catalyzing the splicing reactions, though protein factors are also required in vivo. Splicing occurs by a series of two transesterification reactions, generally with exogenous guanosine as the initiating nucleophile. The intron is excised as a linear piece (though it may subsequently circularize). Source: GOC:krc, PMID:11377794
Comment: Note that Group I introns are known to be found in a number of places: rRNA, mRNA, and tRNA in organelles of fungi, plants, and protists; tRNA and mRNA of bacteria and bacteriophage; rRNA of protists and fungi; and occasionally in mRNA of animal mitochondria (e.g. sea anemone).
