The multifunctional nucleocapsid (N) protein in SARS-CoV-2 binds the ~30 kb viral RNA genome to aid its packaging into the 80-90 nm membrane-enveloped virion. SARS-CoV-2 S binds to human ACE2 with a dissociation constant (K D) of 14.7 nM, though that of SARS-CoV S is 325.8 nM , indicating that SARS-CoV-2 S is more sensitive to ACE2 than is SARS-CoV S. SARS-CoV-2 uses its trimeric spike protein for binding to host angiotensin-converting enzyme 2 (ACE2) and for fusing with cell membrane to gain cell entry [1,2,3,4].This is a multi-step process involving three separate S protein cleavage events to prime the SARS-2-S for interaction with ACE2 [2,3], and subsequent membrane fusion and cell entry.
