Sequences alignment of SARS-CoV-1 and SARS-CoV-2 RBD (S1 subunit) proteins. Symbols between the two pairwise aligned sequences have the usual meaning: a) conservative amino acids where both sequences have the same residues are indicated by “|”; b) Similarities with a high score are marked with “;” and c) the ones with low positive score are indicated by “.”. Gaps are represented by “-”. Numbers are used to guide the identification of the amino acids sequence numbers. See text for more details.
