A variety of experiments, probing both static and dynamic properties of compact globular proteins such as myoglobin1–3, has provided evidence that the protein undergoes something resembling a glass transition at sufficiently low temperature, typically around 200°K. More precisely, myoglobin and several other proteins (hemoglobin, calmodulin) behave as if they possess a large number of conformational substates (CS) about a more or less fixed tertiary structure. These substates are separated by barriers whose energy scale is typically of order 200°K, the freezing temperature. Two questions which immediately come to mind are:
  1. 1.

    To what extent is the transition driven by the solvent, and to what extent is it a consequence of the internal structure of the protein itself?

  2. 2.

    How relevant are the low temperature (i.e., glassy) properties of the protein at higher, physiological temperatures?
