Atomistic reconstruction of the glycosylated SARS-CoV-2 spike. (A) Schematic of the primary structure of the SARS-CoV-2 S protein with the different types of glycan-trees positioned on the different domains as detailed on the right legend. (B,C) Side and top view of the SARS-CoV-2 glycosylated spike in closed conformation. The three types of glycan trees are colored according to the legend on the right. (D,E) Side and top view of the SARS-CoV-2 glycosylated spike in closed conformation such as in (B,C), but with the different domains colored according to the legend used in (A). (F,G) Side and top view of the modeled glycosylated spike from the Brazilian P.1 variant in closed conformation. The potential additional glycan-tree in position N20 is colored in red and indicated with arrows. Representations of the spike in (B–G) were generated with BioExplorer; positions and sources of the glycans are detailed in methods.
