Sequence alignments and characterization of SARS-CoV-2 RBD. a Amino acid alignment for RBD of SARS-CoV-2 and SARS-CoV. Highlighted residues: green, conserved Ser/Thr between two sequences; blue, conserved substitution; pink, new Ser/ Thr residues introduced in SARS-CoV-2; sea green, Ser/Thr residues in SARS-CoV replaced by other amino acids in SARS-CoV-2. b Detailed binding interface of predicted SARS-CoV-2 RBD with ACE2 N-terminal. Possible changes in AAs are highlighted in yellow
