Background
SARS-COV-2 S protein S1 is a powerful weapon of coronavirus SARS-COV-2 to infect human normal cell. Because the receptor binding domain (RBD) lies in S spike protein S1 subunit, which exclusively binds to human ACES2 protein, followed by SARS-COV-2 nuclear materials entering into human cells cytoplasm and starting replication.
