Does sodium dodecyl sulfate (SDS) denature proteins through electrostatic SDS-protein interactions? We show that a protein completely lacking charged side chains is unfolded by SDS in a manner similar to charged proteins, revealing that formal protein charges are not required for SDS-induced protein unfolding or binding.
十二烷基硫酸钠（SDS）是否通过静电 SDS-蛋白质相互作用使蛋白质变性？我们表明，一种完全缺乏带电侧链的蛋白质在 SDS 的作用下展开，其方式类似于带电蛋白质，这表明 SDS 诱导蛋白质展开或结合不需要正式的蛋白质电荷。
