    Abstract

    The COVID-19 disease caused by the SARS-CoV-2 coronavirus has become a pandemic health crisis. An attractive target for antiviral inhibitors is the main protease 3CL Mpro due to its essential role in processing the polyproteins translated from viral RNA. Here we report the room temperature X-ray structure of unliganded SARS-CoV-2 3CL Mpro, revealing the ligand-free structure of the active site and the conformation of the catalytic site cavity at near-physiological temperature. Comparison with previously reported low-temperature ligand-free and inhibitor-bound structures suggest that the room temperature structure may provide more relevant information at physiological temperatures for aiding in molecular docking studies.

    • Crystal structure of the SARS-CoV-2 non-structural protein 9, Nsp9 Dene R. Littler Benjamin S. Gully Rhys N. Colson Jamie Rossjohn # Show footnotes Open AccessPublished:June 09, 2020DOI:https://doi.org/10.1016/j.isci.2020.101258 Summary Many of the SARS-CoV-2 proteins have related counterparts across the Severe Acute Respiratory Syndrome (SARS-CoV) family. One such protein is non-structural protein 9 (Nsp9), which is thought to mediate viral replication, overall virulence and viral genomic RNA reproduction. We sought to better characterise the SARS-CoV-2 Nsp9 and subsequently solved its X-ray crystal structure, in an apo-form and, unexpectedly, in a peptide-bound form with a sequence originating from a rhinoviral 3C protease sequence (LEVL). The SARS-CoV-2 Nsp9 structure revealed the high level of structural conservation within the Nsp9 family. The exogenous peptide binding site is close to the dimer interface and impacted the relative juxtapositioning of the monomers within the homodimer. We have established a protocol for the production of SARS-CoV-2 Nsp9, determined its structure and identified a peptide-binding site that warrants further study to understanding Nsp9 function.

    • Structural basis of receptor recognition by SARS-CoV-2 Jian Shang, Gang Ye, Ke Shi, Yushun Wan, Chuming Luo, Hideki Aihara, Qibin Geng, Ashley Auerbach & Fang Li Nature (2020) Abstract A novel SARS-like coronavirus (SARS-CoV-2) recently emerged and is rapidly spreading in humans1,2. A key to tackling this epidemic is to understand the virus’s receptor recognition mechanism, which regulates its infectivity, pathogenesis and host range. SARS-CoV-2 and SARS-CoV recognize the same receptor - human ACE2 (hACE2)3,4. Here we determined the crystal structure of the SARS-CoV-2 receptor-binding domain (RBD) (engineered to facilitate crystallization) in complex with hACE2. Compared with the SARS-CoV RBD, a hACE2-binding ridge in SARS-CoV-2 RBD takes a more compact conformation; moreover, several residue changes in SARS-CoV-2 RBD stabilize two virus-binding hotspots at the RBD/hACE2 interface.
