Conservation of surface amino acids between SARS-CoV-2, SARS-CoV-1, and CoV-OC43: (A) space-filling model of the NP protein RNA-binding region (PDB [Protein Data Bank] 6M3M) and dimerization region (PDB 2GIB) from SARS-CoV-1 with sequence conservation mapped on the surface projection from ClustalW alignments between SARS-CoV-1 (NCBI BAE93401), SARS-CoV-2 (NCBI YP_009724390), and CoV-OC43 (NCBI YP_009555245). (B) Space-filling model of the full-length SARS-CoV-2 S protein monomer (PDB CVYB) with sequence conservation mapped on the surface projection from ClustalW alignments from SARS-CoV-2 (NCBI YP_009724390), SARS-CoV-1 (NCBI BAE93401), and CoV-OC43 (NCBI YP_009555241).
