Webpathway of a helical protein in terms of a funnel but, interestingly, the pathway appears closely related to the old view of hierarchical folding. Funnel diagrams provide a framework for a stat-istical mechanical treatment of folding in terms of a few critical parameters describing the funnel shape and the flatness of its side.

WebOct 22, 1999 · The Levinthal paradox and folding pathways. Much has been written about the Levinthal paradox and its various resolutions. The paradox involves the observation that there is insufficient time to randomly search the entire conformational space available to a polypeptide chain as an unfolded protein (Levinthal, 1968).
