Figure 3. Oligomerization of AhpE. (a) The AhpE dimer,
characterized by mostly hydrophobic interactions across a
non-crystallographic 2-fold axis. Prominent contributors to the
interface are the two a3 helices and the two b6-b7 hairpin
loops. Side-chains in the interface are shown in stick mode. (b)
The AhpE octamer, formed by operation of the crystallographic
4-fold axis, relating four dimers.
