摘要

Wild-type actin and a mutant actin were isolated from yeast (Saccharomyces cerevisiae) and the poly- merization properties were examined at pH 8.0 and 20 degC. The polymerization reaction was followed either by an increase in pyrene-labeled actin fluorescence or by a decrease in intrinsic fluorescence in the absence of pyrene-labeled actin. While similar to the properties of skeletal muscle actin, there are several important differences between the wild-type yeast and muscle actins.
