Human lymphocytes contain NTPDase (NTPDase-1; ecto-apyrase; ecto-diphosphohydrolase; CD39; EC 3.6.1.5), a cation-dependent enzyme that hydrolyzes ATP and ADP and also other di- and triphosphate nucleosides, acting at an optimum pH of 8.0.
A significant inhibition of ATP and ADP hydrolysis (P <0.05) was observed in the presence of 20 mM sodium azide.

RT-PCR analysis from left ventricle tissue demonstrate different levels of expression of Entpd1 (Cd39), Entpd2 (Cd39L1), Entpd3 (Cd39L3), Entpd5 (Cd39L4) Entpd6, (Cd39L2) and 5'-NT/CD73.
Oligomycin (2 microg/mL) and sodium azide (0.1 mM), both mitochondrial ATPase inhibitors, inhibit only the ATP hydrolysis.

However, suramin and sodium azide were effective inhibitors of ATP and ADP hydrolysis.

The parallel decrease in ATPase and ADPase activities, in the presence of sodium azide, indicated that an ATP diphosphohydrolase (ATPDase) was responsible for these activities.
Identity of ATPDase was confirmed by electrophoretograms of the particulate fractions and Western immunoblots, with an antibody that recognizes ATPDases from different sources.

Sodium azide (0.03-30 mM), at high concentrations (> 0.1 mM), caused a parallel hydrolysis inhibition of ATP and ADP.

In addition, the double mutant is substantially less sensitive to inhibition by azide, a more potent inhibitor of ecto-apyrases than ecto-ATPases.

Comp Biochem Physiol B Biochem Mol Biol. 2010 Mar;155(3):230-40. Epub 2009 Nov 14.

Sodium azide (20mM), ARL 67156 (300 microM) and Suramin (300 microM) differently altered the nucleotide hydrolysis in zebrafish tissues, suggesting the contribution of distinct NTPDase activities.
RT-PCR experiments revealed the existence of a distinct relative entpd1-6 and entpd8 expression profile in brain, liver, and heart.
