Protein folding: Inside the cage

R. John Ellis1

Top

Many newly synthesized bacterial proteins avoid aggregation by folding inside a chaperonin nanocage. Unexpectedly, it turns out that the cage's internal properties can be optimized to accelerate folding.

Proteins are the action molecules of life, but cells face a problem in making them. Proteins consist of amino acids joined into linear polypeptide chains by intracellular structures called ribosomes.
