Nettet9. jan. 1998 · Protein splicing is a posttranslational editing process that removes an in ternal pro tein fragment (intein) from a precursor and ligates the ex ternal pro tein fragments (exteins) to form the mature extein protein. Inteins, once considered an oddity, are now known to be widely distributed. The excised intein is also a stable protein that … 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. Naming conventions The first part of an intein name is based on the … Se mer Protein splicing is an intramolecular reaction of a particular protein in which an internal protein segment (called an intein) is removed from a precursor protein with a ligation of C-terminal and N-terminal external proteins (called Se mer The first intein was discovered in 1988 through sequence comparison between the Neurospora crassa and carrot vacuolar ATPase (without intein) and the homologous gene in yeast (with intein) that was first described as a putative calcium ion transporter. … Se mer Inteins are very efficient at protein splicing, and they have accordingly found an important role in biotechnology. There are more than 200 inteins … Se mer • Gogarten, J Peter; Elena Hilario (2006).

PMC Se mer The process begins with an N-O or N-S shift when the side chain of the first residue (a serine, threonine, or cysteine) of the intein portion of the precursor protein nucleophilically attacks the peptide bond of the residue immediately upstream (that is, the final residue of the … Se mer • Intragenomic conflict • Intron • Protein tag • RNA splicing Se mer • The Intein Database • Shmuel Pietrokovski's Intein database • Short review Se mer
