WebSome proteins can be reversibly folded and unfolded under various conditions. In this experiment we will use acid to denature proteins, and then reverse this by neutralizing the denatured protein solution with the addition of base. WebWhile the proteins are folding, they allow the newly created proteins to fit in. Hydrophobic amino acids line the inner walls of chaperonins, protecting the hydrophobic areas. Also, they correctly refold and unfold aggregated proteins. ATP is used by chaperonins to start the folding process and guarantee proper folding.
