Trehalose Synthesis during Differentiation in Dictyostelium discoideum
The synthesis of [%Z]trehalose has been studied in uiuo at various stages of differentiation in Dictyostelium discoideum. The rate of synthesis was negligible from aggregation until late in the culmination process. At that time, a lOO-fold burst of synthetic activity was observed, amounting to 0.04 pmole of trehalose per min per ml of packed cells. In the course of these studies radioactive mal...

متن کاملA kinetic model of metabolism essential to differentiation in Dictyostelium discoideum.
For the first time, sufficient and appropriate data are available for us to attempt a kinetic model of a portion of the metabolism underlying a simple differentiation system. This has been possible in the cellular slime mold because of: (1) the relative simplicity of the metabolic changes involved, compared to those of more complex organisms; (2) the lack of growth and of extensive qualitative ...
متن کاملInter-relation of cell adhesion and differentiation in Dictyostelium discoideum.
During the development of Dictyostelium discoideum single cells aggregate to form a multicellular organism. The change from the single cell state to multicellularity is mediated by chemotactic cell movement and intercellular adhesion. Dictyostelium represents a side branch in the evolution of multicellular organization in eukaryotes. Therefore, the general importance of any work done in Dictyos...
متن کاملBiochemical and structural characterization of actin from Dictyostelium discoideum.
Actin has been purified from amoebae of Dictyostelium discoideum by a procedure which is notable in that proteolysis has been diminished to undetectable levels and "selective" purification steps have been avoided. The overall yield of this procedure is 5- to 10- fold greater than that of a previous report (Spudich, J. A. (1974) J. Biol. Chem. 249, 6013-6020). The detailed biochemical and struct...
