Current structural information divides the chaperones into five major classes based on their observed molecular weights: Hsp60, Hsp70, Hsp90, Hsp104, and the small Hsps.

E. coli has four major chaperone systems: GroEL/GroES (GroE), DnaK/DnaJ/GrpE (KJE), Trigger Factor (TF), and ClpB (B) (7).

The main difference between chaperones and chaperonins is that chaperones are proteins that assist the covalent folding or unfolding and the assembly or disassembly of other macromolecular structures, whereas chaperonins are a class of molecular chaperones which provide favorable conditions for the correct folding of ...

The key difference between chaperons and chaperonins is that the chaperones perform a wide array of functions including folding and degradation of the protein, aiding in protein assembly, etc., whereas the key function of chaperonins is to assist in the folding of large protein molecules.

Molecular chaperones are specialized in protein folding, whereas energy-dependent proteases such as the proteasome mediate efficient protein degradation. Recent data, however, suggest that molecular chaperones directly cooperate with the ubiquitin/proteasome system during protein quality control in eukaryotic cells.

2.1 Physiology and Mechanism. Chaperonins are a class of molecular chaperone composed of oligomeric double-ring protein assemblies that provide essential kinetic assistance to protein folding by binding non-native proteins and allowing them to fold in the central cavities of their rings.

Chaperonins are a subset of the ubiquitous group of proteins known as molecular chaperones. The chaperonins assist in the correct folding of most proteins in the cell under both normal and stress conditions. Group I chaperonins (Cpn 60) are prokaryotic proteins, also found in the mitochondria of eukaryotes.
