[Spectrum of macroscopic fluctuations in the enzymatic activity of creatine kinase]

Computations were carried out of 725 recordings of enzymic activity of equal shares of creatinkinase solution. It has been shown that in the course of macroscopic fluctuations (synchronous in the macrovolume of "conformation fluctuations") a discrete characteristic spectrum of protein solution state resolution degree of the spectrum is deteriorated. Application of statistical spectral analysis to characterization of the properties of protein aqueous solutions is suggested.
