Folding funnel theory has both qualitative and quantitative application. Visualization of funnels creates a communicating tool between statistical mechanical properties of proteins and their folding kinetics. It suggests the stability of folding process, which would be hard to destroy by mutation given maintained stability. To be more specific, a mutation can occur that leads to blockage of a routes to native state, but another route can take over provided that it reaches th… WebThe folding funnel diagram (see Fig. 1), introduced by Wolynes, Onuchic and Thirumalai2, is intended to provide a pictorial representation of how the Levinthal paradox3, which had dominated discussion of protein folding for many years, is resolved.
