Earthworm fibrinolytic enzyme III-1 (EFE-III-1) was prepared to couple with cross-linking agarose activated by 1,1-Carbonyl-diimidazole (CDI) in this study. Although the activity of the immobilized protease decreased to approximately 64% of the native enzyme, the activity of EFE-III-1 coupled with the resin activated by CDI was higher than that activated by cyanogen bromide (CNBr). The immobilized protease was experimentally demonstrated to hydrolyze IgG, albumin and creatine kinase, besides fibrin(ogen) and plasmin(ogen), suggesting that EFE had a broad substrate specificity.

Keywords: Earthworm fibrinolytic enzyme III-1 (EFE-III-1), carbonyl-diimidazole (CDI), CDI-activated-Sepharose, Sepharose CL-6B, serine-protease
