Chaperone proteins

ive always understood it as the chaperonin create a hydrophobic area to act as a "safe-haven' for the denatured proteins to renature.

protein folding

The chaperonin creates a hydrophobic environment for the denatured protein to be seperated from the factors that caused it to become denatured. But the chaperonin doesnt actually renature the protein itself.

Question about chaperonins and disease

a mutated chaperonin would indeed result in increased protein misfolding. However, I don't think it would generate the Pr^sc version of the prion protein. As far as I know, the only thing that can cause the prion protein (which ...

Re: protein folding

... answers to most of my questions What's their origin? And did "first cell" contain genes for them? What if there would be a mutation and and some chaperonin would be nonfunctional? Would it be lethal? now I read that ribosomes in prokaryotes don't have chaperonins function so it would be lethal ...
