[Study of the dynamics of water-protein systems by the technic of gamma-resonance spectroscopy]

The possibility of using gamma resonance spectroscopy (GRS) for studying the dynamics of water-protein systems is shown in the present work. The experiments were carried out on an albumin-water system. The results obtained are compared with those obtained by the spin label method under the same conditions. The different behaviour of Fe ions which are firmly- and weakly-related with the protein matrix allows to separate the mobility of the whole protein macromolecule and also the mobility of its subunits.
