While we relied on the modeled COVID-19 RBD–ACE2 interaction, the median interaction score of the complex (−1928.8), based on the MD simulation starting from the recently published X-ray structure (PDB 6LZG [21]), was even closer to the SARS-2002 RBD–ACE2 score (−1929.5). This evidence concerns the gene ACE2 and COVID-19.
