  2. Folding funnel - Wikipedia

    en.wikipedia.org/wiki/Folding_funnel

    The folding funnel hypothesis is a specific version of the energy landscape theory of protein folding, which assumes that a protein 's native state corresponds to its free energy minimum under the solution conditions usually encountered in cells. Although energy landscapes may be "rough", with many non-native local minima in which partially ...

  3. Protein folding - Wikipedia

    en.wikipedia.org/wiki/Protein_folding

    Protein before and after folding. Results of protein folding. Protein folding is the physical process by which a protein, after synthesis by a ribosome as a linear chain of amino acids, changes from an unstable random coil into a more ordered three-dimensional structure. This structure permits the protein to become biologically functional.

  4. Hydrophobic collapse - Wikipedia

    en.wikipedia.org/wiki/Hydrophobic_collapse

    The driving force behind protein folding is not well understood, hydrophobic collapse is a theory, one of many, that is thought to influence how a nascent polypeptide will fold into its native state. Hydrophobic collapse can be visualized as part of the folding funnel model which leads a protein to its lowest kinetically accessible energy state.

  5. Anfinsen's dogma - Wikipedia

    en.wikipedia.org/wiki/Anfinsen's_dogma

    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. [1] The dogma was championed by the Nobel Prize Laureate [2] Christian B ...

  6. Levinthal's paradox - Wikipedia

    en.wikipedia.org/wiki/Levinthal's_paradox

    Levinthal's paradox is a thought experiment in the field of computational protein structure prediction; protein folding seeks a stable energy configuration. An algorithmic search through all possible conformations to identify the minimum energy configuration (the native state) would take an immense duration; however in reality protein folding happens very quickly, even in the case of the most ...

  7. Ken A. Dill - Wikipedia

    en.wikipedia.org/wiki/Ken_A._Dill

    Mathematically, the folding process can be visualized as a funnel, in which the several unfolded and misfolded high energy states of the protein occupy positions nearer the top of the funnel, but once the protein begins to fold, its options narrow down with the decrease in conformational entropy and the chain rapidly collapses into its most ...
