Plasma membranes isolated from the protozoan parasite Leishmania donovani were enriched in acid phosphatase (E.C. 3.1.3.2) activity. Cytochemically, the enzyme was distributed uniformly on the surface of intact cells and was localized on the external face of isolated membranes. Physical characteristics and orientation of the membrane-bound enzyme suggest that the organism is adapted for existence in hydrolytic environments.
从原生动物寄生虫杜氏利什曼原虫分离出的质膜富含酸性磷酸酶（E.C. 3.1.3.2）活性。细胞化学分析表明，该酶在完整细胞表面均匀分布，且定位于分离膜的外表面。膜结合酶的物理特性和方向表明，该生物体适合在水解环境中生存。
