Figure 3
The structure of Arc1p-N contains 20 monomers organized in five tetramers per asymmetric unit. (a) The arrangement of the five tetramers (No. 1 in blue, 2 in green, 3 in red, 4 in cyan and 5 in yellow) in the unit cell. (b) The monomers within each tetramer are related by pseudo-twofold rotational symmetry and fall into three conformers (No. 1 in brown, 2 in green and 3 in grey) that differ by the orientation of their N-­terminal α-helix. The central frame in (b) indicates the section shown in detail in the supplementary material1.
