Figure 5

Architecture of gp41 trimer association. (a, b) The gp41 segments are shown as solid surfaces wrapped in a meshwork representing the overall Env trimer, viewed from a perspective parallel to the viral membrane (a) and from the perspective of the viral membrane (b). (c, d) The gp41 ectodomain segments that form the torus and contribute to interprotomer interactions are shown. The views are from a perspective parallel to the viral membrane (c) and from the perspective of the viral membrane (d).
