Fig 4. bNAb epitopes mapped onto the 3D structure of the BG505 SOSIP.664 trimer.

Fig 4

(A) Various bNAbs (not labeled) to different epitope clusters are modeled onto each protomer of the trimer, according to fitting of various EM density maps (see material and methods). (B) bNAbs to different epitope clusters are modeled onto the same EM density map. Only one Fab fragment per trimer is shown for clarity. (C) Footprints of the different bNAb Fab fragment densities displayed in (B). See also methods for further details.
