Energy landscape model of protein folding
WebThe protein frustratometer is an energy landscape theory-inspired algorithm that aims at localizing and quantifying the energetic frustration … WebThe free-energy landscape model is nowadays the most used to describe such phenomena and especially the aging of the protein folding mechanism (1, 5, 6), i.e., the way in which proteins fold to their native state and then unfold (protein denaturation) (6, 7). The model is based on the idea that in complex materials and
