Inter-ring communication is dispensable in the reaction cycle of group II chaperonins.

Abstract excerpt

Chaperonins are ubiquitous molecular chaperones with the subunit molecular mass of 60kDa. They exist as double-ring oligomers with central cavities. An ATP-dependent conformational change of the cavity induces the folding of an unfolded protein that is captured in the cavity. In the group I chaperonins, which are present in eubacteria and eukaryotic organelles, inter-ring communication takes important role for...
