描述

應用

不同种类的马铃薯(S. tuberosum)中存在至少2种同工酶：一种的ATP酶/ADP酶比例较高(∼10)和另一种较低(∼1)。
反应：ATP → ADP+P_i → AMP+2P_i。

Apyrase is used to hydrolyze nucleoside triphosphates and diphosphates. For hydrolysis of organic di and triphosphates, the optimal pH is 6, and for inorganic substrates, the optimal pH is 5.1.[1] Apyrase, from Sigma, has been used in inhibition studies of platelet-aggregation[2].

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[3]. Divalent metal ions are required for activity and best activity is observed with calcium ion at 5 mM.

單位定義

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

外觀
