A method is provided for reversibly modifying a protein or peptide on its glutamine residue(s) by performing a reaction, such as a transglutaminase-catalyzed reaction, between the protein or peptide and an amine-containing reagent, whereby the reagent is linked through its amine function to a side chain of the glutamine residue. Subjecting the modified protein to an appropriate stimulus regenerates the protein or peptide in its original form.
本发明提供了一种对蛋白质或肽的谷
氨酰胺残基进行可逆修饰的方法,该方法是在蛋白质或肽与含胺试剂之间进行反应,如转谷
氨酰胺酶催化反应,试剂通过其胺功能与谷
氨酰胺残基的侧链相连。将修饰过的蛋白质置于适当的刺激下,蛋白质或肽就会以原来的形式再生。
