The Protein-Folding Problem, 50 Years On

Dill, Ken A., MacCallum, Justin L.·2012·Science

Abstract

Protein Folding: Past and Future: Fifty years ago the Nobel Prize in chemistry was awarded to Max Perutz and John Kendrew for determining the structure of globular proteins. Since first viewing their structure of myoglobin, scientists have sought to understand protein folding. Dill and MacCallum (p. 1042 ) review the progress that has been made on three central questions: What is the code that relates sequence to structure? How do proteins fold so fast? Can protein structure be computationally predicted? While we have come some way toward answering these questions, new questions have been gene rated. It is no longer useful to talk about “solving the protein-folding problem”—protein folding has grown into a field of research where the next 50 years promise to be as exciting as the last.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • AlphaFold does not resolve the protein folding problem and does not identify folding pathways.

    “AlphaFold does not resolve the decades-long protein folding challenge, nor does it identify the folding pathways.”

    From AlphaFold, Artificial Intelligence (AI), and Allostery (2022) · cites this paper as [52]

  • According to the funnel hypothesis of protein folding, the native structure of a protein is believed to be the global minimum of its free energy, although many counterexamples exist.

    “According to the funnel hypothesis of protein folding, the native structure of a protein is believed to the global minimum of its free energy [177,193], although many counterexamples exist.”
  • The argument that a protein must have a specific folding pathway because conformational space is too large is fallacious, since free energy falls progressively as the protein folds, providing sufficient guidance.

    “In fact, as has often been pointed out (for example43) this is a fallacious argument, since the free energy falls progressively as the protein folds, providing sufficient guidance44.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
