产品说明

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

包装

100 units in glass bottle
按 ATP 酶单位销售。

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.

单位定义

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

外形

Lyophilized powder containing potassium succinate buffer salts.
