Abstract

Easier with ethyl: Guengerich and co-workers have developed a powerful new approach to the structure elucidation of hydrolytically stable AGT-DNA crosslinks by reductive desulfurization of the thioether linkage between AGT and DNA to convert cysteine DPCs to the corresponding ethyl-DNA adducts, which can be readily characterized by LC-MSn.

摘要

通过还原 AGT 和 DNA 之间的硫醚键将 AGT-DNA 交联物中的半胱氨酸 DPC 转化为相应的乙基-DNA 加合物,从而开发出一种强大的新方法,用于阐明水解稳定的 AGT-DNA 交联物的结构,这可以通过 LC-MSn 轻松进行表征。
