Figure 1: a, Ribbon diagram of the structure of a GroEL subunit (PDB file 1DER of NCBI) 59 highlighting the apical, intermediate and equatorial domains. Figure 2: Characterization of the apical ...

Recent work on the molecular chaperonin GroEL and F1-ATPase has provided paradigms for this ... structure refinement in x-ray crystallography, electron cryomicroscopy (cryo-EM) and fiber diffraction.
