Local Structure in Spider Dragline Silk Investigated by Two-Dimensional Spin-Diffusion Nuclear Magnetic Resonance
Open accessAbstract
The local structure of dragline silk from the spider Nephila madagascariensis is investigated by solid-state nuclear magnetic resonance. Two-dimensional (2D) spin-diffusion experiments show that the alanine-rich domains of the protein form β-sheet structures in agreement with one-dimensional NMR results from a different species of the genus Nephila (Simons, A.; Ray, E.; Jelinski, L. W. Macromolecules 1994, 27, 5235) but at variance with diffraction results. The microstructure of the glycine-rich domains is found to be ordered. The simplest model that explains the experimental findings is a 3 1 -helical structure. Random coils, planar β-sheets, and α-helical conformations are not found in significant amounts in the glycine-rich domains. This observation may help to explain the extraordinary mechanical properties of this silk, because 3 1 -helices can form interhelix hydrogen bonds.

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.
