Dependence of ATPase activity on ATP concentration. ATPase activity of freshly purified D10 plasma membranes expressed as nmol Pi/min/mg protein was measured over ATP concentrations ranging from 0.5 to 5 mM. ATPase activity of parasite plasma membranes tested without ATP and absorbance due to ATP hydrolysis were subtracted. Error bars represent standard deviations from means of three separate experiments, each performed in quadruplicate.
