Three other purification methods have been described in the literature—for cucumber 16) and for the enzyme from green squash 17,18). Table I summarizes the salient molecular properties of ascorbate oxidase purified according to the different procedures mentioned above. A detailed purification table is presented in References 15 and 18, and includes the enzyme yield calculated on the basis of total protein present in the crude juice. The yield is 14% for the method of Lee and Dawson... 

As previously mentioned, laccase is very closely related to ascorbate oxidase. The principal molecular architecture and arrangement of the mononuclear and trinuclear copper centers are the same. Furthermore, spectroscopic and kinetic properties are similar in many circumstances. Therefore, the catalytic mechanism of the dioxygen reduction should be the same for both. Kinetic studies on fungal and tree laccases have been...
