The intracellular and extracellular acidic alpha-mannosidase in cultures of fibroblasts from mucolipidosis-II patients has normal kinetics. The extracellular activity in cultures of cells from mannosidosis patients is normal, but a mutant enzyme is associated with the cell surface and intracellular fraction. The results support the involvement of membrane cycling and recognition markers in lysosomal enzyme localization.
黏脂贮积症II型患者成纤维细胞培养物中的细胞内和细胞外酸性α-甘露糖苷酶具有正常的动力学。甘露糖苷贮积症患者细胞培养物中的细胞外活性正常,但一种突变酶与细胞表面和细胞内部分相关。这些结果支持膜循环和识别标记物参与溶酶体酶定位。
