【摘要】 经硫酸铵盐析沉淀和ＰＡＧＥ制备电泳，从赤子爱胜蚓（Ｅｉｓｅｎｉａｆｏｅｌｉｄｅ）粗品中分离纯化出五种纤溶酶组份（Ⅰ、Ⅶ、Ⅷ、Ⅸ、Ⅹ），在ＰＡＧＥ中均呈现单一带。组份Ⅶ、Ⅷ、Ⅹ能将纤维蛋白原中α、β、γ链依次降解，对α链亲和力最大。组份Ｘ不能降解４３．５ＫＤ、４０ＫＤ、２４．５ＫＤ片段。组份Ⅰ对α链有较高亲和力而对γ链无降解作用。更多还原

【Abstract】 By ammonium sulfate precipitation and preparative electrophoresis, five fibrinolytic enzymes(Ⅰ、Ⅶ、Ⅷ、Ⅸ、Ⅹ) were isolated and purified from the extract of the earthworm (Eisenia foelide), they were single band determined by PAGE. The α,β,γ chains of fibrinogen were successively degraded by EFE Ⅶ,Ⅷ,Ⅸ and Ⅹ respectively, and had the most affinity to α chain. Component X can not degrade the fragment of 43.5,40,24 5 KD. Component I had high affinity to α chain, but can not degrade r chain.更多还原
