Staphylococcal L-asparaginase has been purified 400-fold with 40% recovery. The procedure involves ammonium sulphate precipitation and a column chromatography on Sephadex G-200 gel filtration). The enzyme is composed of not identical subunits. protein (pI 4.4) with the approximate molecular weight of 125,000 (estimated by Sephadex G-200 gel filtration). The enzyme is composed of not identical subunits. The polyacrylamide-SDS gel electrophoresis indicated two subunits with molecular weight 18,000 and 22,000.
葡萄球菌L-天冬酰胺酶已被纯化400倍,回收率为40%。该纯化过程包括硫酸铵沉淀和Sephadex G - 200凝胶过滤柱色谱法。该酶由不同的亚基组成,是一种蛋白质(等电点4.4),通过Sephadex G - 200凝胶过滤法估计其分子量约为125,000。该酶由不同的亚基组成。聚丙烯酰胺 - SDS凝胶电泳显示有两个亚基,分子量分别为18,000和22,000。
