CAT activity as a function of pH (a) and temperature (b). The different pH buffers (each at a concentration of 50 mM) were trisodium citrate (pH 2.5 to 4), sodium acetate (pH 5), sodium phosphate (pH 6 to 7.5), tris (pH 8), ethanolamine (pH 9), and sodium phosphate (pH 10 to 12.5). Each datum point represents the average of the analysis of triplicate values.
