33Group I catalytic intron — Group I catalytic introns are large self splicing ribozymes. They catalyze their own excision from mRNA, tRNA and rRNA precursors in a wide range of organisms. The core secondary structure consists of nine paired regions (P1 P9). These fold to… …
34Group II intron — is a class of intron found in rRNA, tRNA, mRNA of organelles in fungi, plants, protists, and mRNA in bacteria. Self splicing occurs in vitro (for a few of the introns studied to date), but protein machinery is probably required in vivo. In… …
35Group III intron — is a class of introns found in mRNA genes of chloroplasts in euglenoid protists. They have a conventional group II type dVI with a bulged adenosine, a streamlined dI, no dII dV, and a relaxed splice site consensus. Splicing is by two… …
36Small t intron — exist in some plasmid vectors used for protein expression.The function of this intron in the vectors is unknown, but it is theorized that it might be involved in splicing or translation efficiency.Vectors contain such as pME18s contain it …
