| Quality【质量】 | High Activity |
| Application【应用】 | Apyrase is used to hydrolyze nucleoside triphosphates and diphosphates. Apyrase, from Sigma, has been used in inhibition studies of platelet-aggregation . Product A2230 is a high activity apyrase. 在多种马铃薯普通栽培种中至少发现了两种同工酶：一种具有高 ATP 酶/ADP 酶比率(约 10)，另一种该比率较低(约 1)。 反应：ATP → ADP+Pi → AMP+2Pi。 |
| Biochem/physiol Actions【生化/生理作用】 | 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 . Divalent metal ions are required for activity and best activity is observed with calcium ion at 5 mM. |
