FIG. 4.
Fractions of catalase C-10 at a Ve of 13.6 (peak C-10a) contain arginase activity. Catalase C-10 was subjected to FPLC fractionation. Individual fractions (50 μl) were allowed to react with l-arginine, and arginase activity was assessed by measurement of the production of urea and ornithine. The experiment was carried out twice with similar results.
