In a recent issue of Nature, Chambers et al.¹ combined bioinformatics, biochemistry, and X-ray crystallography to uncover the presence of a ubiquitin-like machinery in bacteria, which was believed to be unique to archaea and eukaryotes. This study highlights the prevalence of a ubiquitin-like system in bacteria that was later adopted by the eukaryotes for various purposes such as protein degradation.

无处不在的泛素：从细菌到真核生物


在最近一期的《自然》杂志上，钱伯斯等人。 ¹结合了生物信息学、生物化学和 X 射线晶体学，揭示了细菌中存在的类泛素机制，这种机制被认为是古细菌和真核生物所独有的。这项研究强调了细菌中普遍存在的类泛素系统，该系统后来被真核生物用于蛋白质降解等各种目的。
