Polyphenoloxidase (‘Tyrosinase’): Purification and Molecular Properties
Nature, 1957POLYPHENOLOXIDASE has been prepared from potatoes by Kubowitz1 and from cultivated mushrooms (Psalliota campestris) by Keilin and Mann2. The degree of purification attained was certainly very high, and it is conceivable that the enzyme was obtained in a pure or near pure state.

Polyphenoloxidase from DeChaunac grapes
Journal of the Science of Food and Agriculture, 1983AbstractPolyphenoloxidase (PPO) from red grape cultivar, DeChaunac, grown in New York State was isolated and purified 17‐fold by using Phenyl Sepharose CL‐4B column. Disc gel electrophoresis revealed near homogeneity of three isoenzyme bands. The molecular weight of this enzyme ranged from 73 000 to 85 000. The temperature and pH optima of the purified

Interaction between Thiourea and Insect Polyphenoloxidase
Nature, 1959POLYPHENOLOXIDASES of plant and animal origin are known to be inhibited by copper complexing sulphur compounds. When investigating the effect of thiourea on polyphenoloxidase of the wax-moth, Galleria mellonella L. (Lepidoptera), we noticed that degree of inhibition diminished during an aerobic incubation of the enzyme with the inhibitor and the ...

Inactivation of Polyphenoloxidase by Pulsed Light
Journal of Food Science, 2013Abstract The effect of pulsed light on the inactivation of polyphenoloxidase (PPO) in model solutions was investigated focusing on the effect of enzyme concentration and total energy dose of the treatment. PPO inactivation increased with the dose of the treatment.
