Type II Chaperonins and Early Functional Studies

Discovery of TYpe II Chaperonins and Early Functional Studies 

Moreover, the thermophilic archaebacterium Sulfolobus shibitae was shown to contain a heat shock protein (TF55) with 40% amino acid sequence identity to mouse TCP-1 (Trent et al., 1991). TF55 formed a double toroid and was able to bind unfolded substrates in vitro, thus strongly implicating it as a functional chaperonin molecule.
