Scheme of the competing forces affecting protein folding and unfolding. Heat stress (HS) causes the unfolding of proteins, while chaperonins promote their refolding. Trehalose functions as a protein stabilizer preventing denaturation and aggregation; however, it also interferes with the proper functioning of heat shock proteins (here represented by Chaperonin) in the refolding of denatured proteins.
