Technical advances have pushed the resolution limit of single-particle cryo-electron microscopy (cryo-EM) throughout the past decade and made the technique accessible to a wide range of samples. Among them, multisubunit DNA-dependent RNA polymerases (Pols) are a prominent example. This review aims at briefly summarizing the architecture and structural adaptations of Pol I, highlighting the importance of cryo-electron microscopy in determining the structures of transcription complexes.
技术的进步推动了单颗粒冷冻电子显微镜(cryo-EM)的分辨率极限在过去十年中不断提高,使得该技术能够应用于广泛的样品。其中,多亚基 DNA 依赖性 RNA 聚合酶(Pols)就是一个突出的例子。本文旨在简要总结 Pol I 的结构和结构适应性,强调 cryo-EM 在确定转录复合物结构方面的重要性。
