'''Chaperonins''' (CPN) are oligomeric proteins that mediate the folding of polypeptide chains. Group I CPN are found in bacteria, chloroplasts and mitochondria. For an introductory overview, see [http://en.wikipedia.org/wiki/Chaperonins Chaperonins in Wikipedia].

Line 30: Line 8:
The most characterized CPN are in the GroEL/GroES complex from ''Escherichia coli'' and CPN60/CPN10 from ''Thermus thermophilus''. The larger subunit (GroEL, CPN60) contains 3 domains. The apical domain is the one which binds the substrate. Group II CPNs are found in eukaryotic cytosol and archaea. Thermosome is a CPN complex found in archaea. CCT is a CPN complex found in eukarya.
