Before revision:  We apply this framework to three relevant proteins of the SARS-CoV-2 , the virus responsible for COVID-19, namely non-structural protein 9 (NSP9) replicase, main protease, and the receptor-binding domain (RBD) of the S protein.
After revision:  We apply this framework to three relevant proteins of the SARS-CoV-2 target proteins: main protease, and the receptor-binding domain (RBD) of the S protein.
