  • Title: Kinetic analysis of the polymerization process of actin.
    Author: Arisaka F, Noda H, Maruyama K.
    Journal: Biochim Biophys Acta; 1975 Aug 19; 400(2):263-74. PubMed ID: 1164507.
    Abstract:
    The polymerization process of actin was examined by measuring the amount of flow birefringence and by analyzing release of labeled inorganic phosphate from the bound [gamma-32P]ATP upon polymerization of G-actin to F-actin. Comparison of the above experimental results with the electron microscopic data of Kawamura and Maruyama (J. Biochem., 67, 437-457, 1970) suggested that growth and redistribution steps occurred simultaneously during polymerization. Attempt was made to simulate the polymerization process of actin by calculating the kinetic equations numerically. The results of simulation suggested that it was necessary to take into consideration the association and dissociation between F-actin particles as well as the association and dissociation between F-actin and G-actin.
