The chaperonin field has captured the attention of numerous scientists in recent years. A rapidly increasing number of reviews and articles have tried to elucidate the mechanisms by which these multimeric complexes drive the fo- ing of newly synthesized and denatured proteins. An obvious common theme of chaperonin research first arose from the study of their structural features. All members of this class consist of multiple subunits that form cylindrical structures, which encage proteins in a cave-like environment where folding of proteins takes place according to the current view. Since the...
