Term Information

Accession: GO:0000374
Name: Group III intron splicing
Ontology: biological_process
Synonyms: mRNA splicing
Alternate IDs: None
Definition: The splicing of Group III introns. This occurs by a ribozymic mechanism where the intron sequence forms a distinct 3D structure, characteristic of Group III introns, that is involved in catalyzing the splicing reactions, though protein factors are also required in vivo. Splicing occurs by a series of two transesterification reactions begun by a bulged adenosine residue within the intron sequence as the initiating nucleophile. The intron is excised as a lariat. Though very similar in structure and mechanism to Group II introns, Group III introns are smaller and more streamlined and the splice site consensus sequences are not as well conserved. Source: GOC:krc, PMID:11377794
Comment: Note that Group III introns are known to be found in mRNA of plastids of euglenoid protists.
