Antisera were raised to preparations of hexosaminidase isoenzymes A and B purified from human liver. Protein that cross-reacted with the liver hexosaminidase was detected by an antibody-consumption method. A cross-reacting protein with a low molecular weight (20000) was partially characterized and purified from control human liver. This protein is also present in the liver of patients with Tay-Sachs disease or with Sandhoff's disease. Hexosaminidases A and B gave an immunological reaction of partial identity with the low-molecular-weight protein. The possible identity of the low-molecular-weight cross-reacting protein as a subunit of hexosaminidase is discussed.
制备了针对从人肝脏中纯化的己糖胺酶同工酶A和B的抗血清。通过抗体消耗法检测与肝脏己糖胺酶发生交叉反应的蛋白质。从对照人肝脏中部分鉴定并纯化了一种低分子量(20000)的交叉反应蛋白。这种蛋白也存在于患有泰-萨克斯病或桑德霍夫病患者的肝脏中。己糖胺酶A和B与低分子量蛋白发生部分同源的免疫反应。讨论了低分子量交叉反应蛋白作为己糖胺酶亚基的可能同源性。
