Fig. 6: E. histolytica ribosome intersubunit bridges and conformational changes occur in LSU upon association.

a The ribosomal small subunit (left) and large subunit (right) are shown in light khaki and blue, respectively. The residues involved in intersubunit bridges are shown in the atomic sphere, and bridges are labeled. The bridges shown in gray color were not observed in the 75S ribosome. A detail of interacting residues is provided in Supplementary Table 5. b The LSU coordinates built using 75S cryo-EM maps (light blue) docked into the LSU Cryo-EM map (gray) are shown. The rRNA helices that become ordered upon association with the SSU are labeled.
