Values presented as mean ± standard deviation (). Data in the same column with the same superscript are not significantly different at . = maximum velocity; is the Michalelis–Menten constant (substrate concentration required for an enzyme to reach half ). nd means not determined. WA-f₅₀ and WA-f₇₅: water-extractable fractions from WA obtained at 50 and 75% ammonium sulphate saturation, respectively. WB-f₅₀ and WB-f₇₅: water-extractable from WB obtained at 50 and 75% ammonium sulphate saturation, respectively.
