An intein is a segment of a protein that is able to excise itself and join the remaining portions (the exteins) with a peptide bond during protein splicing. Inteins have also been called protein introns, by analogy with (RNA) introns. The first part of an intein name is based on the scientific name of the organism in which it is found, and the second part is based on the name of the corresponding gene or extein. For example, the … WebMay 18, 2024 · The structure also provides a possible explanation for the low levels of premature C-terminal cleavage associated with VidaL C –extein ... we performed an extensive structural and biochemical characterization of the atypically split intein, VidaL, work that successfully guided the application of this system for protein semisynthesis … first pharyngeal pouch derivatives
