Publication Abstract from PubMed
The thermodynamics of protein folding are dictated by a complex interplay of interatomic interactions and physical forces. A variety of unnatural protein-like oligomers have the capacity to manifest defined folding patterns. While the energetics of folding in natural proteins is well studied, little is known about the forces that govern folding in modified backbones. Here, we explore the thermodynamic consequences of backbone alteration on protein folding, focusing on two types of chemical changes made in different structural contexts of a compact tertiary fold. Our results reveal a surprising favorable impact on folding entropy that accompanies modifications that increase disorder in the ensemble of unfolded states, due to differences in the solvation of natural and unnatural backbones.
