Human brain hexosaminidase C was separated from isoenzymes A and B by Sephadex G-200 gel filtration. Properties of the enzyme were studied, particularly its isoelectric-focusing profile, pI4.80. These findings indicate that hexosaminidase C is identical with the major residual component of Sandhoff fibroblasts with respect to substrate specificity, pI and activity pH optimum.
通过葡聚糖凝胶G-200凝胶过滤法,从己糖胺酶A和B的同工酶中分离出了人脑海绵状血管瘤己糖胺酶C。对该酶的特性进行了研究,尤其是其等电聚焦图谱,pI为4.80。这些发现表明,就底物特异性、pI和活性最适pH而言,己糖胺酶C与桑德霍夫成纤维细胞的主要残留成分相同。
