understanding the biological functions of sulfation in peptides and proteins has been hampered by the lack of methods to control its spatial or temporal distribution in the proteome. Herein, we report that fluorosulfate can serve as a latent precursor of sulfate in peptides and proteins, which can be efficiently converted to sulfate by hydroxamic acid reagents under physiologically relevant conditions.

硫酸化广泛存在于真核蛋白质组中。然而,由于缺乏控制其在蛋白质组中的空间或时间分布的方法,对肽和蛋白质中硫酸化的生物学功能的理解受到了阻碍。在此,我们报道氟硫酸盐可以作为肽和蛋白质中硫酸盐的潜在前体,在生理相关条件下可以通过异羟肟酸试剂有效地转化为硫酸盐。光笼罩异羟肟酸试剂进一步实现了功能性磺肽的光控激活。这项工作为探索硫酸化在肽和蛋白质中的功能作用提供了一个有价值的工具。
