Total volume, ml. Incubation: 10 minutes, ° C. Ordinate, 7 phosphate liberated/mg. protein/10 minutes, abscissa NaPP concentration (M/liter). liberated was 88% of the control (no NaPP). When the molar ratio of ATP to NaPP was :1, only 57% of the control activity was found. Tentatively, this was interpreted as an inhibition caused by the removal of the activating divalent cations through their chelation by the pyrophosphate. Verification was deferred until the present.
