Fig. 2From: SARS-CoV-2: phenotype, genotype, and characterization of different variantsCoronavirinae subfamily structure. Coronavirinae subfamily contains surface viral proteins, namely spike glycoprotein (S), which mediates interaction with the ACE2 cell surface receptor. Viral membrane glycoproteins (M) and envelope (E) of SARS-CoV-2 embedded in the lipid bilayer of viral membranes coat the viral RNA helical nucleocapsid [16] (created with BioRender.com)Back to article page
