Figure EV4. Details of the functionally important assembly factors’ interactions in the cryo‐EM map of the cytoplasmic pre‐40S.

Figure EV4

The unfiltered cryo‐EM map is shown at two different contour levels (gray and red mesh).
  1. N‐terminal α‐helix of Tsr1 (orange) interacting with helix 44.
  2. Visualization of the flipped out position of the decoding center base A1754 at the top of helix 44 (pink).
  3. Interactions of the conserved loop of Tsr1 with uS19 (green) and uS13 (pink).
  4. Interaction of the Pno1 (green) C‐terminal KH domain (containing a GxxG RNA binding motif shown in blue) with the 3′ terminal bases of the rRNA (orange).
