Figure 5
Fragment of an S21 protein model from E. coli 70S ribosome at 3.0 Å resolution (PDB ID/EMDB ID 5we4/8814). (a) In the deposited coordinates, many side chains outside a well resolved map and a proline inside a regular alpha helix may raise suspicion. (b) After sequence re-assignment and side-chain rebuilding with findMy­Sequence, the map features are better explained by the model. Only residue range 34–44 in chain u and a corresponding map are shown for clarity.
