Protein folding and chaperonins.
The folding of polypeptide chains in cells, following either translation or translocation through membranes, must take place under conditions of extremely high protein concentrations. In addition, folding into a correct structure must occur in the presence of other rapidly folding species, and at temperatures known to destabilize aggregation-prone folding intermediates. To facilitate folding in vivo, molecular chaperones have evolved that stabilize protein folding intermediates, thus partitioning them towards a pathway leading to the native state rather than forming inactive aggregated structures.
