'''CONFORMATIONAL VARIABILITY IN THE REFINED STRUCTURE OF THE CHAPERONIN GROEL AT 2.8 ANGSTROM RESOLUTION'''
===CONFORMATIONAL VARIABILITY IN THE REFINED STRUCTURE OF THE CHAPERONIN GROEL AT 2.8 ANGSTROM RESOLUTION===




==Overview==
<!--  
Improved refinement of the crystal structure of GroEL from Escherichia coli has resulted in a complete atomic model for the first 524 residues. A new torsion-angle dynamics method and non-crystallographic symmetry restraints were used in the refinement. The model indicates that conformational variability exists due to rigid-body movements between the apical and intermediate domains of GroEL, resulting in deviations from strict seven-fold symmetry. The regions of the protein involved in polypeptide and GroES binding show unusually high B factors; these values may indicate mobility or discrete disorder. The variability of these regions may play a role in the ability of GroEL to bind a wide variety of substrates.
The line below this paragraph, {{ABSTRACT_PUBMED_8846220}}, adds the Publication Abstract to the page
