Structure of the SARS-CoV-2 virus: Spike (S) is the surface glycoprotein that mediates the interaction of SARS-CoV-2 with the cell surface receptor angiotensin-converting enzyme 2 (ACE2). The membrane glycoprotein (M) and envelope (E) are embedded in the host cell-derived lipid membrane which encapsulates the viral nucleocapsid.
