    The characterization of the protein structural dynamics was done with the following analyses: a) flexibility with the Root Mean Square Fluctuation (RMSF); b) analysis of collective modes of wild-type and mutants (correspondence/correlation calculation); c) conformational sampling using hybrid methods; d) distance analysis between the two residues of the catalytic dyad; e) SASA analysis for different regions; f) analysis of the frequency of occurrence of mutants in the patient data deposited in the GISAID database. 2.1.

    Wild-type and apo crystal SARS-CoV-2 Mpro structures with 1.91 Å resolution (PDB ID: 7C2Y [DOI: 10.2210/pdb7C2Y/pdb]) were used to generate 48 mutants with single point mutations [17]using PyMOL software [The PyMOL Molecular Graphics System, Version 2.0 Schrödinger, LLC].

    suggested: (PyMOL, RRID:SCR_000305)
    The normal modes were calculated using the DIMB (Iterative Mixed-Basis Diagonalization) module [24] implemented in CHARMM software [25, 26] considering all the atoms of the protein and a force field corresponding to the CHARMM36m [27].

    The Heatmap, Violin and Boxplot representations were generated in Python using the Pandas [34, 35], NumPy [36], Matplotlib [37] and Seaborn [38] libraries.

    Using the PISA web server, we calculate the solvation free energy gain upon formation of the interface, interface area and number of potential hydrogen bonds and salt bridge [39].

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
