Raman spectra of crystalline subglobular proteins exhibit peaks in the low-frequency spectral range. These peaks can be related to resonance oscillations of subglobules and possibly play an important role in the catalytic act. The low-frequency spectral features were not observed in aqueous solutions. According to the hydrodynamics, the corresponding oscillations must be overdamped. The results obtained by the methods of molecular dynamics how that the Q-factor of subglobular oscillations can be larger than 10, which stimulated further experimental studies of solutions of proteins.
