[Conformational dynamics of proteins and the simplest molecular "machines"].
A mathematical model is developed for conformational motions of proteins. The mechanism is shown to be by local jump diffusion via conformational substrates. The model is analysed in terms of experimental data obtained by Mössbauer spectroscopy and X-ray scattering. From comparative analysis the validity of a continual model is deduced. The correlation between electron transport activity and protein conformation motions is discussed within the local jump mechanism. An equation is established to describe the relationship between electron tunneling rate and correlation time of conformational movement.
