The present invention concerns a method for site-selective modification of a target protein or peptide by use of an acylation tag comprising a single lysine residue and at least three histidine residues. Upon contact with an acylating reagent, the target protein or peptide becomes modified at the ε-amine of the lysine residue of the acylation tag.
本发明涉及一种使用酰化标签对目标蛋白质或肽的位点选择性修饰的方法,该酰化标签包括一个单个赖
氨酸残基和至少三个组
氨酸残基。当与酰化试剂接触时,目标蛋白质或肽在酰化标签的赖
