Abstract:
The thermosome, the chaperonin of the archaea, and its homologue from the cytosol of eukaryotes, known as TRiC or CCT, form a distinct subfamily of the chaperonins that does not depend on a co-chaperonin for protein folding activity. Recent structural data obtained by cryo- electron microscopy and X-ray crystallography provide the first insights into a novel mechanism remarkably different from that of the bacterial GroEL-GroES system.
