Membrane‐Bound Cyclic AMP Phosphodiesterase in Chemotactically Responding Cells of Dictyostelium discoideum
Open accessAbstract
In cells of the cellular slime mold, Dictyostelium discoideum, that respond chemotactically to cyclic AMP, cell‐bound cyclic AMP phosphodiesterase was studied under two conditions: in suspensions of living cells with external cyclic AMP as a substrate, and in the 27000 ×g sediment of cell homogenates. Under both conditions a drastic increase of cell‐bound phosphodiesterase activity in the developmental phase preceding cell aggregation was found. In non‐aggregating mutants this increase is smaller or absent. The particle‐bound cyclic AMP phosphodiesterase has an optimum at pH 7.0–8.0. In vivo it is resistant to inhibition by external glutathione and to a macro‐molecular phosphodiesterase inhibitor from Dictyostelium discoideum; in particle fractions enzyme activity is partially sensitive to these inhibitors. A possible function of this enzyme in the chemo‐tactic receptor system is discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
