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.

Outer envelope membranes from chloroplasts are isolated as right-side-out vesicles [PDF]

, 1992
Outer envelope membranes were isolated from purified chloroplasts of pea leaves. The sidedness of the vesicles was analyzed by (i) aqueous polymer-two phase partitioning, (ii) the effect of limited proteolysis on the outer-envelope proteins (OEP) 86 and ...
