target for the site-specific modification of fusion systems and new approaches to natural product proteomics. A detailed study of pantetheine analogues was performed in order to identify suitable partners for covalent protein labeling inside living cells. A rapid synthesis of pantothenamide analogues was developed and used to produce a panel which was evaluated for in vitro and in vivo protein labeling
体内载体蛋白标记最近已成为融合系统的位点特异性修饰和天然产物蛋白质组学新方法的一个有吸引力的目标。对泛酰巯基乙胺类似物进行了详细研究,以确定活细胞内共价蛋白标记的合适伙伴。开发了泛酰胺类似物的快速合成,并用于生产用于体外和体内蛋白质标记评估的面板。动力学比较允许构建结构-活性关系,以查明载体蛋白标记选择的接头、染料和生物正交报告基因。最后,生物正交泛酰巯基乙胺类似物在体内以高特异性靶向载体蛋白,并在粗细胞裂解物中与报告分子进行化学选择性连接。
