Reconstruction of the Env Spike, Filtered to 28 Å, and Rendered
(A) A rendered view of the complex at a 2 sigma contour level. The chirality of the distal portion is evident.
(B) As in (A), rotated 60° around the 3-fold symmetry axis.
(C) A slab through the density in the orientation represented in panel (B), revealing the cavity at the centre of the structure. The membrane is coloured in cyan. The volume corresponding to gp41 has been coloured in gray, and the remaining gp120 volume in orange.
Scale bar = 100 Å.
