MeSH definition : A family of multisubunit protein complexes that form into large cylindrical structures
which bind to and encapsulate non-native proteins. Chaperonins utilize the energy
of ATP hydrolysis to enhance the efficiency of PROTEIN FOLDING reactions and thereby
help proteins reach their functional conformation. The family of chaperonins is split
into GROUP I CHAPERONINS, and GROUP II CHAPERONINS, with each group having its own
repertoire of protein subunits and subcellular preferences.;
