Fig. 1: Overall structure of SARS-CoV S2 fusion machinery in post-fusion state.
From: Cryo-EM analysis of the post-fusion structure of the SARS-CoV spike glycoprotein
a Schematic diagram of the SARS-CoV S2 subunit ectodomain. The uncolored region represents the undetermined region in our structure. L linker region, UH the upstream helices, FP fusion peptide, CR connecting region, HR heptad repeat, CH central helix, BH β-hairpin, SD3 subdomain 3. b–e Cartoon representation of the SARS-CoV S2 trimer in post-fusion state colored as shown in a.
