This means that the unfolded protein form of protein #1 will be less stable than the protein #2 leading to a greater stability when folded. " - Funnel model of protein folding

Energy landscapes, including … Anfinsen's dogma, also known as the thermodynamic hypothesis, is a postulate in molecular biology. It states that, at least for a small globular protein in its standard physiological environment, the native structure is determined only by the protein's amino acid sequence. The dogma was championed by the Nobel Prize Laureate Christian B. Anfinsen from his research on the folding of ribonuc…
