In this report, we show that an ecto-(Ca, Mg)-apyrase activity is present on EBV-transformed B cells, but not on B or T lymphomas. The coincidence between CD39 expression and ecto-apyrase activity on immune cells suggests that CD39 may be an ecto-apyrase.

Long-term use of the drug chloroquine diphosphatase, used in malaria prophylaxis, rheumatoid arthritis and other conditions, was found to cause bluish - grey pigmentation in the hard palate. Finally, we show that CD39 indeed has ecto-apyrase activity by expression in COS-7 cells. This supposition is supported by the observation that the amino acid sequence of CD39 is significantly homologous to those of several newly identified nucleotide triphosphatases.
