Multiple Sequence Alignment and Secondary Structure Elements (SSE%) analysis of SARS-CoV-2 RBD–CD299 and SARS-CoV RBD–CD299 complexes during (MD) simulation: A: Multiple Sequence Alignment using ClustalW, Asterisks (∗) indicated fully conserved residues, the colon symbol (:) indicates conservation between groups of very similar properties, and the period symbol (.) indicates conservation between groups of weakly similar properties. (B: RBD SARS-CoV-) (C: RBD SARS-CoV) Secondary Structure Elements (SSE%), alpha helix and beta strand regions are highlighted in red and blue backgrounds, respectively.
