Intein

（重定向自Extein）

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 in a process termed protein splicing. Inteins have also been called "protein introns".

Intein-mediated protein splicing occurs after the intein-containing mRNA has been translated into a protein. This precursor protein contains three segments — an N-extein followed by the intein followed by a C-extein. After splicing has taken place, the resulting protein contains the N-extein linked to the C-extein; this splicing product is also termed an extein.

释义	Extein 英语例句库 Intein is an intervening polypeptide which can catalytic self-cleavage from a pre-protein accompanied by the concomitant joining of the two flanking polypeptides (the extein) through a peptide bond. 蛋白质内含肽是一个蛋白质前体中的多肽序列，可以催化自身从蛋白质前体中断裂，使两侧的蛋白质外显肽连接成成熟的蛋白质。英语百科 Intein （重定向自Extein） 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 in a process termed protein splicing.
