Table 3 ATPase activity in the presence of 2 mM concentrations of various nucleotides.

From: Preparation of pure and intact Plasmodium falciparum plasma membrane vesicles and partial characterisation of the plasma membrane ATPase

  ATPase activity (% of control)
Nucleotide Triphosphate Diphosphate Monophosphate
Adenosine 100 72.6 ± 16.7 -9.2 ± 9.3
Guanosine 120.8 ± 19.6 55.4 ± 17.1 N.D.
Cytosine 64.2 ± 7.6 N.D. N.D.
Uridine 101.4 ± 55.0 N.D. N.D.
  1. ATPase activity of isolated D10 plasma membranes tested without nucleotide and absorbance due to the nucleotide hydrolysis was subtracted. Values are means of three separate experiments, each performed in quadruplicate ± standard deviations and are expressed as % of control in presence of ATP. N.D.: not determined.
