[The mechanism of action of pressure on intramolecular protein dynamics].

The physical mechanisms of pressure influence on the protein dynamics and parameters of Mossbauer spectra were investigated. The pressure effects measured for human serum albumin using Rayleigh Scattering of Mossbauer Radiation techniques were described using the model of local diffusion. Parameters of this model were determined by analysing the experimental data. As a result an estimation of approximate values for activation volumes was performed. It was shown that the obtained values are well consistent with the previous experimental results.
