Protein folding as an evolutionary process

Sharma, Vivek; Kaila, Ville R.I.; Annila, Arto - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 6, pp. 851-862

Protein folding is often depicted as a motion along descending paths on a free energy landscape that results in a concurrent decrease in the conformational entropy of the polypeptide chain. However, to provide a description that is consistent with other natural processes, protein folding is...
