The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters host cells by binding its spike protein to the angiotensin-converting enzyme 2 (ACE2) receptor of the host. The SARS-CoV-2 spike protein is a trimer of S1/S2 heterodimers with 2 ACE2 receptor binding domains (RBD) attached via a hinge region, allowing conformational flexibility. Neutralizing antibodies
