The paper "Funnels, Pathways and the Energy Landscape of Protein Folding: A Synthesis" by Bryngelson, Onuchic, Socci, and Wolynes explores the complexity of protein folding and introduces a statistical approach to understanding the energy landscape of protein conformation. The authors argue that the complexity of protein folding can be understood by considering the statistical properties of the energy landscape, which describes the energetics of protein conformations. This approach helps explain unique behaviors such as specific folding pathways and the distinction between folding processes common to all sequences and those peculiar to individual sequences. The paper also discusses the implications of these ideas for interpreting experiments and simulations of protein folding thermodynamics and kinetics, including the origin of metastable collapsed unfolded states and curved Arrhenius plots. The authors further analyze the relationship between these quantitative ideas and folding pathways, uni-exponential vs. multi-exponential behavior in protein folding experiments, and the effect of mutations on folding. The paper unifies several previously proposed ideas about protein folding mechanisms and provides a framework for understanding protein structure prediction and engineering.The paper "Funnels, Pathways and the Energy Landscape of Protein Folding: A Synthesis" by Bryngelson, Onuchic, Socci, and Wolynes explores the complexity of protein folding and introduces a statistical approach to understanding the energy landscape of protein conformation.
