multimolecular crowding conditions of live cells is highly desirable for the analysis and engineering of proteins without using genetic manipulation. N‐Sulfonyl pyridone (SP) is reported as a new reactive group for protein sulfonylation. The ligand‐directed SP chemistry was able to modify not only purified proteins in vitro, but also endogenous ones on the surface of and inside live cells selectively and rapidly
在不使用基因操作的情况下,非常需要开发用于在活细胞多分子拥挤条件下标记内源蛋白的生物正交方法。据报道,N-磺酰基吡啶酮(SP)是蛋白质磺酰化的一个新的反应基团。配体导向的SP化学不仅能够在体外修饰纯化的蛋白质,而且能够选择性且快速地修饰活细胞表面和内部的内源性蛋白质,从而可以将内源性蛋白质原位转化为基于FRET的生物传感器。
