| Abstract: | An endopeptidase (Cudrania protease) with a molecular mass of 76 kDa has been purified from the fruits of Cudrania cochinchinensis (Lour.) Kudo et Masam. The enzyme was stable between pH 6 and 10 at 30 degrees C for 60 min. The enzyme activity was inhibited by diisopropyl fluorophosphate, chymostatin, and aprotinin, but not by EDTA or pepstatin. These results indicated that the enzyme was a serine protease. |
