Question

Quizplus · Accepted Answer

Chaperonins are proteins that assist in the folding of newly synthesized proteins. They create a specialized environment in which the protein can fold in a stepwise, energy-efficient manner. Chaperonins do not mediate the unfolding of proteins or promote protein denaturation. They also do not counteract the laws of thermodynamics, but rather they facilitate protein folding in accordance with these laws. While some proteins may be able to fold properly without the assistance of chaperonins, many rely on chaperonins to achieve their functional structure.
