The three-helix-bundle protein GS- α 3 W. (a) Variation of histogram of bRMSD with temperature. At high temperatures, there is a broad distribution of bRMSD with values > 10 Å. At lower temperatures there are three clearly separated clusters. Representative structures from these clusters are also shown (color) aligned with the native structure (gray). (b) Temperature dependence of specific heat, C v , and the ratio h r of the observed helix content and the helix content of the native structure.
