[Relationship between the spectra of macroscopic fluctuations of creatine kinase enzyme activity and the pH of a protein solution].
A canonic shape of the spectrum of macroscopic fluctuations of enzymic activity in creatinkinase solutions [1] is revealed within wide pH range. With pH decrease (from 10.0 to 6.0) the discreteness and reproducibility of the spectra decreases, at pH 5.0 no canonic spectrum was revealed. The discovered dependence of the spectrum shape on pH illustrates possibilities of spectral analysis of macroscopic fluctuations for characterization of the states of protein aqueous solutions.
