Distribution of Horseradish Peroxidase in Horseradish Plants [PDF]

HortScience, 1996
Peroxidases are an enzyme family that displays a wide range of forms, functions, and distribution in the plant kingdom. Peroxidase extracted from horseradish is one of a few enzymes that had been widely used in industrial and clinical research. Horseradish peroxidase (HRP, EC 1.11.1.7, donor: hydrogen-peroxide oxidoreductase) has been used to estimate ...
