Determination of CAT activity was performed by the method of
Hong et al. (2012). The reaction mixture consisted of 2.8 mL H2O2
(40 mM, in 50 mM sodium phosphate buffer, pH 7.0) and 0.2 mL
enzyme extract. The decomposition of H2O2 was measured by the
decline in absorbance at 240 nm during 120 s. The specific activity
