Phosphoproteins in dictyostelium discoideum

Journal of Supramolecular Structure and Cellular Biochemistry, 1981
AbstractThe phosphoproteins of Dictyostelium discoideum were compared at different stages of development by polyacrylamide gel electrophoresis. Certain phosphoproteins of vegetative amoebae were conserved while others appeared and disappeared during development.

The cytochromes of Dictyostelium discoideum

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1983
1. Low temperature (77 K), reduced oxidized difference spectra of "purified" mitochondria of Dictyostelium discoideum revealed the presence of b, c and a-type cytochromes. 2. The same components were also identifiable in intact organisms, the only possible discrepancies from the contribution by "microsomal" b-type cytochromes which showed major maxima ...

Coated vesicles in Dictyostelium discoideum

Journal of Ultrastructure Research, 1981
Coated vesicles have been found in vegetative and aggregation-stage amoebae of Dictyostelium discoideum. Coated pits in the plasma membrane can be visualized by electron microscopy of both thin-sectioned cells and negatively stained preparations of sheared membranes.

Auxotrophic mutants of Dictyostelium discoideum [PDF]

Nature, 1978
THE cellular slime mould Dictyostelium discoideum is a unicellular organism in its vegetative stage. On starvation, slime mould amoebae gather into aggregates which pass through a morphogenesis culminating in mature fruiting bodies consisting of dead stalk cells supporting a sphere of viable spores1. The laboratory strains of D. discoideum are normally

Cell aggregation in Dictyostelium discoideum

Developmental Biology, 1961
Abstract The capacity of small populations of myxamebas of Dictyostelium discoideum to aggregate, i.e., to form pseudoplasmodia, was investigated under contrasting cultural and environmental conditions, including: (1) populations developed in situ on washed or purified agar where growth of myxamebas was restricted by limiting the nutrient ...

DNA polymerase of Dictyostelium discoideum

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1976
Only one molecular weight species of DNA polymerase was found in different developmental stages of the eukaryotic microorganism Dictyostelium discoideum. The molecular weight of this DNA polymerase is estimated to be about 127 000 by sucrose gradient centrifugation. The enzyme is present in all stages of growth and development, including dormant spores.

CHEMOATTRACTANT SIGNALING IN DICTYOSTELIUM DISCOIDEUM [PDF]

Annual Review of Cell and Developmental Biology, 2004
▪ Abstract  Dictyostelium is an accessible organism for studies of signaling via chemoattractant receptors. Chemoattractant-mediated signaling events and components are reviewed and presented as a series of connected modules, including excitation, inhibition, G protein–independent responses, early gene expression, inositol lipids, PH domain-containing

The Inositolcycle of Dictyostelium Discoideum

1990
Transmembrane signal transduction is characterized largely by the interaction between its components: ligand, receptor on the surface of cells, G-protein subunits at the inner face of the plasma membrane, and effector enzymes. The effector enzymes may vary widely depending on the organism and the ligand, and include adenylate cyclase, guanylate cyclase,

Pacemaker mutants of Dictyostelium discoideum

Developmental Biology, 1974
Abstract In this paper, I report measurements of the time intervals between aggregation waves in two morphogenetic mutants of Dictyostelium discoideum NC-4. The mutants both have abnormal wave periodicity and their abnormalities are interpreted in terms of defects in the cellular properties which underlie wave propagation.

Phagosomal Proteins of Dictyostelium discoideum

Journal of Eukaryotic Microbiology, 1997
ABSTRACT. In recognizing food particles, Dictyostelium cell‐surface molecules initiate cytoskeletal rearrangements that result in phagosome formation. After feeding D. discoideum cells latex beads, early phagosomes were isolated on sucrose step gradietns.
