Several coterminous bands could be observed by PAGE of natural Eisenin Ⅰ and several coterminous peaks of Eisenin Ⅰ were also detected with MALDI-TOF-MS when the molecular weight of three main peaks are 24, 645, 25, 052 and 25, 281, separately. The amino acid composition of Eisenin Ⅰ(pI. 8) is specilized with high content of acidic amino acids and low content of alkaline amino acids; At the same time, the content of Ser and Thr are quite high and that of Lys, Met, Phe and Trp are quite low. Eisenin Ⅰ is highly homologous with serine proteases. Then, by fibrin plate assay, Eisenin Ⅰ was identified to be a plasmin and also a plasminogen activator, and the fibrinolytic activity was inhibited by PMSF (an inhibitor of serine proteases).
