- Abstract
- We have investigated the structure of spider dragline silk by X-ray diffraction over a broad temperature range from room temperature up to thermal denaturation conditions. The dominating signal from the beta-sheet crystallites is analyzed. Pronounced changes of scattering intensity starting at temperatures around 150 degrees C are observed. These changes are discussed in view of the respective lattice constants, crystal size, size distribution, crystallite number density and amino acid composition.
