Fig. 1. Structure of eIF3 core.
a-c, Segmented eIF3 core, colored variably by subunit, seen from different orientations.d, Two-dimensional representation of the three-dimensional structure of the eIF3 octamer core. The helical bundle is represented by colored bars. Zigzagged line on eIF3c indicates possibly unstructured N-terminal tail. The eIF3a C-terminal region (not present in the structure reported here) is not shown in this schematic representation. e-g, Fitting of the eIF3 core model in its cryo-EM segmented density.
