Banana Polyphenoloxidase. Preparation and Properties [PDF]
Plant Physiology, 1963 Griffiths (13) has presented evidence indicating that the browning reactions of banana fruit result from the enzymic oxidation of dopamine (3,4 dihydroxyphenylethyliamine) by polyphenoloxidase. Although dopamine does occur in various fruits and vegetables (23), it has not previously been implicated as an important substrate in browning reactions.

Inhibition of Palmito Polyphenoloxidase by Halide Salts [PDF]
Journal of Enzyme Inhibition, 1998 The inhibitory properties of halide salts on palmito polyphenoloxidase (PPO) are described. Halide salts have the same inhibitory effect on the two forms of palmito PPO separated by hydrophobic chromatography. Fluoride and chloride ions showed a non-competitive, mixed type inhibition while bromide and iodide ions were found to be non-competitive ...

Some Biochemical properties of polyphenoloxidase from spearmint (Mentha arvensis)
Brazilian Archives of Biology and Technology, 2009 Polyphenoloxidase (PPO; EC 1.14.18.1) extracted from Mentha arvensis leaves was isolated by (NH4)2SO4 precipitation and extensive dialysis. Its optimum pH and temperature varied with the substrate. The PPO showed activity with various diphenols.
