Application

In diverse varietà di S. tuberosum si trovano almeno due isoenzimi: uno con un rapporto ATPasi/ADPasi elevato (∼10) e un altro con un rapporto basso (∼1).
Reazione: ATP → ADP+Pi → AMP+2Pi.
Apyrase is used to hydrolyze nucleoside triphosphates and diphosphates. Apyrase, from Sigma, has been used in inhibition studies of platelet-aggregation [1]. Product A2230 is a high activity apyrase.

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.

Packaging

Sold on the basis of ATPase units.

Physical form

Lyophilized powder containing potassium succinate buffer salts.

Preparation Note

Derived from red potato

Other Notes

One unit will liberate 1.0 μmole of inorganic phosphate from ATP or ADP per min at pH 6.5 at 30 °C.
