ABSTRACT

The SARS-CoV-2 main protease of (Mpro) is an important target for SARS-CoV-2 related drug repurposing and development studies. Here, we describe the steps for structural characterization of SARS-CoV-2 Mpro, starting from plasmid preparation and protein purification. We detail the steps for crystallization using the sitting drop, microbatch (under oil) approach. Finally, we cover data collection and structure determination using serial femtosecond crystallography. For complete details on the use and execution of this protocol, please refer to Durdagi et al. (2021).
