Abstract

The effect of caldesmon (CD) and subfragment 1 of myosin (S1) on the structural state of tropomyosin (TM) modified with N-(iodoacetyl)-N-(1-naphthyl-5-sulfo)-ethylene-diamine (1.5-IAEDANS) in single myosin-free skeletal muscle fibers was studied using polarized microfluorimetry. S1 was performed from skeletal muscles of rabbits, whereas CD and TM were prepared from the smooth muscle of chicken gizzards. An analysis of experimental data revealed that CD initiates and increases the motility of 1.5-IAEDANS-TM, while S1 decreases it. In the presence of CD S1 binding to actin is accompanied by significant changes in the fluorescent label motility. It is supposed that CD and S1 induce in TM conformational changes which interfere with the protein interaction with F-actin.

Abstract

It was shown on erythrocyte ghosts that the parameters of fluorescence of 2,6-toluidine-naphthalene-sulfonate (2,6-TNS) and fluorescamine undergo similar changes after irradiation. After a dose of 100 Gy the equally effective concentrations of Fe2+ were 1-5 microM and 50-100 microM with regard to changes in the rate of fluorescence of fluorescamine and 2,6-TNS, respectively, and greater than 100 microM with regard to fluorescence anisotropy.
