Details

Ascorbate oxidase is a homodimeric enzyme, which comprises 552 amino acid residues per subunit (zucchini). It corresponds to a molecular mass of 70 kDa per subunit. This enzyme is mainly found in plants, fungi and eubacteria.This enzyme is involved in a redox system involving ascorbic acid. The enzyme is highly specific for L-ascorbic acid and a few analogs. The pH optimum for enzymatic activity is in the range of pH 5.5 to 7.0. The activity at pH 4.5 and 8.3 is approximately 50% maximal activity.
