Abstract

1. 1. ATP hydrolytic activity in whole cell homogenates of some protozoa was assayed in the presence or absence of dithiothreitol. 2. 2. The activities in all protozoan cell homogenates, except Toxoplasma gondii, ranged from 0.6 to 32 μmol/mg protein/hr, irrespective of the presence or absence of dithiothreitol. 3. 3. A remarkably higher activity, l l,690 μmol/mg protein/hr, was observed for T. gondii in the presence of dithiothreitol. 4. 4. These results indicate that the higher ATP hydrolytic potency observed for T. gondii is not universal to protozoa, rather it is unique to T. gondii.
