Proteins are large, complex molecules essential to all of life. Nearly every function that our body performs - contracting muscles, sensing light, or turning food into energy - relies on proteins, and how they move and change. What any given protein can do depends on its unique 3D structure. WebThe non-teleological reason why proteins take on one (or only a few) forms, is based on the energetics of how they fold. Most proteins have one highly stable tertiary structure, which is often organized around a core region of hydrophobic residues. great leather macbook bags

WebOct 1, 2007 · How do proteins fold and why do they fold in that way? These questions have engaged the experimentalists and theoreticians with gathering intensity since about 1960, when Chris Anfinsen first showed that proteins are able to fold to their native structure all by themselves, without outside help. 0:23 WebHere, we show that a protein’s capacity to evolve is enhanced by the mutational robustness conferred by extra stability. We use simulations with model lattice proteins to demonstrate how extra stability increases evolvability by allowing a protein to accept a wider range of beneficial mutations while still folding to its native structure.
