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

Potato acid phosphatase (EC 3.1.3.2) was used to remove the eight phosphate groups from alphas1-casein. Unlike most acid phosphatases, which are active at pH 6.0 or below, potato acid phosphatase can catalyze the dephosphorylation of alphas1-casein at pH 7.0. Although

A new manganese-containing acid phosphatase has been isolated and crystallized from sweet potato tubers. The pure enzyme contains one atom of manganese per Mr = 110,000 polypeptide and shows phosphatase activity toward various phosphate substrates. The pH optimum of the

Formation of phosphate esters by kinases has long been recognized as an important process in biochemistry, but the reverse reaction, hydrolysis of phosphate esters by phosphatases, has attracted less attention. Recent work suggests that phosphatases are as important as kinases
