Fig. 2: Cryo-EM maps and atomic models of Ab1303-BG505 and Ab1573-BG505 complexes.

a, b Cryo-EM density maps of Ab1303-BG505 (a) and Ab1573-BG505 (b) complexes shown from the top (left) and side (middle). Right: cartoon diagrams of the structures with N-linked glycans shown as pink spheres. Highlighted in colors include: gp120 subunits (light gray), gp41 (dark gray), Ab1303 VH (dark green) and VL (pale green) domains and Ab1573 VH (dark teal) and VL (light teal) domains. The gp120 V1V2 and V3 regions are shown in orange and blue, respectively.
