Abstract: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), discovered in December 2019, is responsible for the CoVid-19 global pandemic. The SARS-CoV-2 genome encodes sixteen non-structural proteins, many of which are essential for viral replication. Using the Protein Data Bank and various bioinformatics tools, we analyzed structure, sequence, and mutations of SARS-CoV-2 proteins. Non-structural proteins represent potential targets for discovery and development of small molecules that combat SARS-CoV-2.
The focus of this work is SARS-CoV-2 non-structural protein 13 (Nsp13), which functions as a helicase, unwinding double-stranded RNA. Nsp13 collaboratively works with a complex consisting of four other non-structural proteins (Nsp7, two copies of Nsp8, and Nsp12), which act as an RNA-dependent RNA polymerase to copy the viral genome. Studying the structure of Nsp13 will enhance our understanding of its mechanism of action at the atomic level and help identify ways to inhibit this important virally-encoded enzyme.
