Surface glycosylation of SARS-CoV-2 virus. (A) Overall structure of SARS-CoV-2 showing the spikes (colored green) arrayed on the surface of the virus (Coronavirus Credit: Maria Voigt/RCSB PDB). (B,D) Sagital views of the ribbon diagram (B) and the molecular surface (D), showing the structural organization of the spike (PDB code 6ZGE). The three S-glycoproteins forming the SARS-CoV-2 spike are colored yellow, pink, and purple, respectively. The RBD in each S-glycoprotein is colored green. (C,E) Front views of the ribbon diagram (C) and the molecular surface (E), showing the structural organization of the spike. N-glycan chains occupying the putative N-glycosylation sites in the three S-glycoproteins, are colored cyan and represented in spheres.
