I'm reading about protein folding on Wikipedia and I stumbled on a bit about a class of proteins called chaperones that aid in the folding of proteins by:

However, they aren't considered to be catalysts because they do not actually speed up the folding process. My thought is that without these chaperones, the polypeptides chain would go through a long process of finding a proper intermediate and therefore should be considered catalysts.

Where am I going wrong in my thinking?
