Figure 2.

Image of a GroEL monomer showing the location of the potassium ion-binding site as well as the regions that were identified as being most flexible in a comparison to the previously determined wild-type GroEL structure (PDB code 1xck). Residues 44–45, 202–204 and 260–268 line the folding cavity, while residues 477–487 are located on the outside surface near the ATP-binding site and ring–ring interface of the GroEL complex. This figure was generated using PyMOL v.0.99 (DeLano, 2002 ▶).
