peptide bond

1.The peptide bond is the same as the imido bond of biuret.

处于等电点状态的蛋白时凝固最完全、最迅速。

2.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.

蛋白内含肽是一个蛋白体中的多肽序列，可以催化自身从蛋白体中断，侧的蛋白外显肽连接成成熟的蛋白。
