一般說明
甘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。
應用
在一项研究中，利用甘薯酸性磷酸酶与戊二醛和氨丙基可控孔径玻璃共价结合后，可用作柱前酶反应器。它还被用于研究酪氨酸、组氨酸和半胱氨酸作为甘薯磷酸酶中Mn(III)的配体的用途。
甘薯酸性磷酸酶被作为去磷酸化试剂用于硫色素测定，以检测生物样品中的硫胺。在该测定中，该酶比小麦胚芽酸性磷酸酶或α-淀粉酶更有效。
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，通过以下反应非特异性地催化磷酸单酯和酸酐水解，产生无机磷酸盐： APaseR-PO4 + H2O --------------- R-OH + HOPO3 2+它们在磷酸盐生成、转运和再循环中的作用对于细胞的代谢和能量转导过程至关重要。Apase作为一类酶，可能与调节过程中的激酶具有同等重要的作用。

Induction of phosphatase activity is an important component of the plant cell response to phosphate deficiency. Suspension cell cultures of Brassica nigra contain two major inducible acid phosphatase (APase) isozymes; vacuolar phosphoenolpyruvate (PEP) APase and cell wall nonspecific APase. Polyclonal
