Abstract

Catalase (CAT:EC1.11.1.6) was purified from Van Apple. The purified enzyme preparation was obtained with a final recovery of enzyme activity of about 11.5% and a specific activity of 29.43 U/mg proteins. The purified catalase has an optimum temperature of activity at 50oC. As regards pH, the enzyme has an optimum activity of pH 5. Vmax and Km values were determined by Lineweaver-burk graphs. Potassium cyanide, citric acid, MnCl2, NaCl, NaNO2 and CuSO4 were used as inhibitor.
