Fig. 4

Structures of BG505 SOSIP antigens in complex with polyclonal antibodies targeting gp120–gp120 interface (A, B) and base epitopes (C). BG505 SOSIP trimers are shown in gray with N-linked glycans in golden yellow. Antibodies are colored using the same scheme as in Figs. 1 and 2. Inferred heavy and light chains for each antibody are represented in different colors and labeled in each panel (HC and LC, respectively). The most relevant epitope/paratope components are indicated in the panels. Surface representation is used for the full immune complex (left side of each panel). Trimer residues in direct contact with the antibodies are colored blue (ribbon and stick representation). Engineered stabilizing residues are represented as sticks and colored orange. EM Map is displayed as transparent light gray surfaces in panels (A) and (B).
