一般描述
马铃薯酸性磷酸酶是一种磷酸单酯酶,具有多种分子形式,分子量相近,但等电点不同。
应用
检测了马铃薯酸性磷酸酶在各种表面活性剂介质中的活性。 双(2-乙基己基)磺基琥珀酸钠,Brij 35和3mM的SDS抑制磷酸酶活性,而表面活性剂十六烷基三甲基溴化铵增强活性。
马铃薯酸性磷酸酶已用于评估新基因产物的潜在过敏性的研究中。 在一项研究中,它还用于在pH 7.0下从酪蛋白中去除8个磷酸基团。
生化/生理作用
酸性磷酸酶(APase)是一个酶家族,在pH 4-7最佳条件下,非特异性地催化磷酸单酯和酸酐水解产生无机磷酸盐。
单位定义
在pH 4.8 ,37℃ 下,一单位每分钟可水解 1.0 μmole的对-硝基苯基磷酸酯。

The effect of three different classes of surfactants viz., anionic, cationic and neutral on catalytic activity of potato acid phosphatase (AcPase) was studied. Anionic surfactants bis(2-ethylhexyl) sodium sulfosuccinate (AOT) and sodium dodecyl sulfate (SDS) inhibited AcPase activity completely at 3

An acid phosphatase (orthophosphoric monoester phosphohydrolase, acid optimum; EC 3.1.3.2) isoenzyme from wheat germ was purified 7000-fold to homogeneity. The effect of wheat germ sources and their relationship to the isoenzyme content and purification behavior of acid phosphatases was investigated.
