Application

Apyrase is used to hydrolyze nucleoside triphosphates and diphosphates. Apyrase, from Sigma, has been used in inhibition studies of platelet-aggregation [1].
At least two isoenzymes are found in different varieties of S. tuberosum: one with a high ATPase/ADPase ratio (∼10) and another with a low ratio (∼1).
Reaction: ATP → ADP+Pi → AMP+2Pi.

Other Notes

One unit will liberate 1.0 micromole of inorganic phosphorus per minute at pH 6.5 at 30 °C
Mixture of high and low ratio isoenzymes.

Packaging

Sold on the basis of ATPase units.

Biochem/physiol Actions

Apyrase is found in all eukaryotes and some prokaryotes. Apyrase, from potato, has a crucial role in regulating growth and development. Apyrase is involved in the inactivation of synaptic ATP as a neurotransmitter following nerve stimulation and in the inhibition of ADP induced platelet aggregation to prevent thrombosis [2]. Divalent metal ions are required for activity and best activity is observed with calcium ion at 5 mM.
