COVER The novel coronavirus (SARS-CoV-2; blue) approaches a human cell (pale pink). The viral spike protein (gray) binds to a receptor (ACE2; dark pink) on the cell surface. This allows SARS-CoV-2, the virus responsible for the COVID-19 pandemic, to infect human cells. The structures of the viral spike protein, the full-length ACE2, and the complex of ACE2 with the receptor binding domain of SARS-CoV-2 have been elucidated, providing structural basis for development of antiviral drugs and vaccines.
