Schematic diagram showing the viral particle structure of SARS-CoV-2 (A), and the genome organization of SARS-CoV-2 genes (B). The structural components of the spike (S) protein; S2 contains signal peptide (SP), N-terminal domain (NTD), and receptor binding domain (RBD). The S1 contains fusion peptide (FP), heptad repeat domains (HR1 and HR2), trans-membrane domain (TMD) and cytoplasmic domain (CD). The arrowhead indicated the furin and TMPRSS2 cleavage sites. (B) The genome organization of SARS-CoV-2 genes
