Abstract:
:During development of Dictyostelium discoideum, the cellular specific activity of beta-glucosidase increases before aggregation, declines to low levels during pseudoplasmodium formation, and increases rapidly during culmination. In addition, two electrophoretically distinct isozymes of beta-glucosidase are present at different times of development. Using enzyme-specific monoclonal antibodies, we have shown that changes in the level of enzyme specific activity are closely paralleled by changes in the relative rate of beta-glucosidase synthesis in vivo and by corresponding changes in the relative cellular concentration of functional beta-glucosidase mRNA. Thus, the developmental synthesis of beta-glucosidase is controlled at a pretranslational level. Furthermore, our experiments have demonstrated that both beta-glucosidase isozymes consist of a single subunit of identical molecular weight. This result is consistent with the previous finding that both isozymes are encoded by the same gene and suggests that the isozymes differ solely with respect to post-translational modification.
