冠状病毒使用RNA依赖性RNA聚合酶(RdRp)来复制和表达其基因组。RdRp与其他非结构蛋白(nsps)结合形成复制-转录复合物(RTC),进行RNA合成,加帽和校对。然而,RdRp的结构长期以来仍然难以捉摸,从而限制了我们对冠状病毒基因组表达和复制的理解。最近,报道了SARS-CoV-1 RdRp的冷冻电镜结构。在持续的COVID-19大流行的推动下,SARS-CoV-2聚合酶和相关因子的结构数据以前所未有的速度出现,迄今已发布了20多个结构。这篇综述概述了目前可用的冠状病毒RdRp结构,并概述了它们如何与功能研究一起,导致对病毒聚合酶的分子理解,其与辅助因子的相互作用以及有前途的抗病毒药物可能抑制冠状病毒复制的机制。
Coronaviruses use an RNA-dependent RNA polymerase (RdRp) to replicate and express their genome. The RdRp associates with additional non-structural proteins (nsps) to form a replication–transcription complex (RTC) that carries out RNA synthesis, capping and proofreading. However, the structure of the RdRp long remained elusive, thus limiting our understanding of coronavirus genome expression and replication. Recently, the cryo-electron microscopy structure of SARS-CoV-1 RdRp was reported. Driven by the ongoing COVID-19 pandemic, structural data on the SARS-CoV-2 polymerase and associated factors has since emerged at an unprecedented pace, with more than twenty structures released to date. This review provides an overview of the currently available coronavirus RdRp structures and outlines how they have, together with functional studies, led to a molecular understanding of the viral polymerase, its interactions with accessory factors and the mechanisms by which promising antivirals may inhibit coronavirus replication.
