abstract = {In a quasielastic neutron scattering experiment, the
picosecond dynamics of alpha-amylase was investigated for
the folded and the unfolded state of the protein. In order
to ensure a reasonable interpretation of the internal
protein dynamics, the protein was measured in D2O-buffer
solution. The much higher structural flexibility of the pH
induced unfolded state as compared to the native folded
state was quantified using a simple analytical model,
describing a local diffusion inside a sphere. In terms of
this model the conformational volume, which is explored
mainly by confined protein side-chain movements, is
parameterized by the radius of a sphere (folded state, r =
1.2 Angstrom; unfolded state, 1.8 Angstrom). Differences in
conformational dynamics between the folded and the unfolded
state of a protein are of fundamental interest in the field
of protein science, because they are assumed to play an
important role for the thermodynamics of folding/unfolding
transition and for protein stability. (C) 2003 Elsevier
