摘要:

细胞内的环境异常复杂,其中生物大分子的浓度超过300 mg/mL并占据着大约30%的细胞内空间. 然而,直到目前为止大多数的蛋白质研究仍然在细胞外或是甚至非常稀的缓冲液中进行. 细胞内磁共振(In-cell NMR)提供了一个可以直接非损伤地获取细胞内原子水平信息的方法. 虽然In-cell NMR在近10年里有了较大的发展,但是这一技术尚未成熟. 在该篇综述中,作者首先总结制约这一技术发展的因素以及研究中需要注意的事项,最后讨论了未来的发展方向.

Abstract:

The cellular interior contains macromolecules at concentrations exceeding 300 mg/mL and volume occupancies of 30%. Until recently, however, most protein studies were performed in vitro and in dilute solutions. In-cell NMR spectroscopy provides a means to gain atomiclevel data noninvasively in the cellular environment. Although in-cell NMR has recently undergone significant advances, it is still in its infancy. Here, we review the limitations and potential pitfalls of in-cell NMR and recent advances in the field.

Key words: in-cell NMR, protein, Escherichia coli, EPR
