Characterization of the ATP-G-actin aggregates formed at low potassium chloride concentration
The Biochemical Journal
|April 1, 1984
Abstract:
The ATP-G-actin aggregates formed by incubation of ATP-G-actin in 7.5 mM-KCl were characterized by electron-microscopical observation, by high-pressure liquid chromatography and by the study of the 1,N6-etheno-ATP-ATP exchange reaction between the free and the actin-bound nucleotide. In 30 mM-KCl the initial rate of the reduced-viscosity increase is found to be directly related to the amount of the aggregates formed in the course of the preincubation in 7.5 mM-KCl.
