Apparent specific activity is defined as the amount of substrate that is converted by the enzyme in one second, the apparent catalytic efficiency is the number of oxidation cycles that the enzyme is capable of in one second. The enzymes were dosed at equal levels of syringaldazine activity. Standard deviations are shown and significant difference (p ≤ 0.05) of apparent specific activity and apparent catalytic efficiency column-wise are shown as superscripted letters (a–d), significance difference (p ≤ 0.05) of apparent specific activity and apparent catalytic efficiency row-wise are shown as superscripted letters (x–y).
