title: [Computer simulation of protein molecular dynamics].
abstract: A review of the works on the computer simulation of the globular protein dynamics is given. Methodological aspects of the simulation procedure are outlined briefly. Main peculiarities of protein dynamics revealed in the course of simulation of pancreatic trypsin inhibitor and cytochrome c are presented. The causes of "anomalous" processes, inherent in the simulated behaviour of model proteins are discussed. These "anomalous" processes are: continuous drift of the structure and its deviation from the experimental one, determined by X-ray analysis. Both processes are supposed to be the consequence of the reduced conformational rigidity of the model protein in comparison to the real one. Among the possible reasons for this reduced rigidity absence of the water molecules, hydrating peptide groups in the real protein, may be mentioned. Analogy between "anomalous" processes in the simulated protein dynamics and some phenomena observed in the real proteins during their functioning is drawn.
