Effect of EDTA on the activity of Tk-SP. Tk-SP was incubated at 80°C for 20 min in 50 mM Tris–HCl (pH 7.5) containing EDTA at the concentration indicated, and the relative activities were determined using azocasein as the substrate. Each experiment was carried out three times, and the average values are shown together with the error bars.
