Fig 2. 3D reconstruction of the gp12 decameric assembly.

(A) Class averages of the negatively stained gp12 decamer. The bottom row shows three class averages corresponding to stacked double decamers, demonstrating robustness of the 2D classification. The box size for class averages is 349.4 Å. (B) 3D reconstruction. Top left, front view. Top right, cutaway view. Bottom left, top view. Bottom right, tilted by 45° from the view on the left.
