Abstract

Homology modeling of unknown proteins is based on the assumption that highly similar sequences are likely to share the same fold. However, this does not provide any information on the stability of a given fold, which is ultimately determined by the subtle interplay of enthalpic and entropic contributions. Herein it is shown that ab initio atomistic simulations can be used to predict the effect of point mutations on the stability of a protein fold. The calculations indicate that the fold stabilities of two proteins of similar sequence and identical fold, the villin and advillin C-terminal headpiece fragments, are different and that the same P62A point mutation has a dramatic effect on the fold of villin but a minor one on that of advillin. These predictions were subsequently validated by NMR and CD experiments.

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.
