Abstract

Light scattering spectra of lysozyme dissolved in glycerol are analyzed over broad ranges in frequency and temperature. It is shown that the dynamic transition observed earlier in a lysozyme/glycerol sample at T ∼ 270 K [Biophys. J. 79 (2000) 2728] is related to the appearance of a slow relaxation process in the GHz frequency window. It is also pointed out that the dynamic transition in the lysozyme/glycerol system happens at a temperature very close to the dynamic transition temperature of bulk glycerol. These results support the idea that biopolymers are 'slaves' of solvents and that the latter controls the dynamic transition.
