Figure 3.
Crystal structure of AFV1–140. (A) AFV1–140 crystal
structure (gray) superimposed onto ΔN_AFV1–132 (cyan) with a
r.m.s deviation of 1.54 Å on the Cα backbone. Helices are
sequentially labeled α'1 to α'5. (B) Electrostatic surface in
the same orientation. (C) Head-to-tail dimer in which one chain
is shown as a gray ribbon and the other is represented as light
green surface. (D) Tetramer of the asymmetric unit is composed
of a dimer of dimers. Detergent molecules (β-OG) are
represented with orange surfaces. Figs. were created with Pymol.
