Figure 1.
Conformational plasticity of importin β bound to the sIBB domain. (A) Asymmetric unit content with two importin β • sIBB domain complexes in different conformations shown as coils. Importin β is colored red and blue and the sIBB domain yellow and orange. (B) Representative 2Fo − Fc electron density computed at 3.15 Å resolution and contoured 1.5σ above background. This figure was generated with Pymol (28).
