  • Title: [Influence of monovalent cations on the ATP activity and superprecipitation of actomyosin].
    Author: Pavliashvili GI, Simonidze MSh, Kupatadze RM, Zaalishvili MM.
    Journal: Biofizika; 1982; 27(3):362-4. PubMed ID: 7093313.
    Abstract:
    Dependence of ATP activity and superprecipitation of reconstructed actomyosin on ionic strength, pH and ionic radius of the monovalent cations at different temperatures has been investigated. It is established that the optimum of ATP activity and superprecipitation of synthetic actomyosin at the presence of different monovalent cations was in the ionic strength range 0.09-0.1, in the pH range--7.5-8.0. The monovalent cations according to their efficiency are arranged in the following order: Na+ greater than or equal to K+ greater than Rb+ greater than Li+ and Cs+.
