peroxidase

[pĕ-rok´sĭ-dās]

any of a group of iron-porphyrin enzymes that catalyze the oxidation of some organic substrates in the presence of hydrogen peroxide.

pe·rox·i·dase

(pĕ-rok'si-dās),

Hydrogen peroxide-reducing oxidoreductase; type of enzymes in animal and plant tissues that catalyzes the dehydrogenation (oxidation) of various substances in the presence of hydrogen peroxide, which acts as hydrogen acceptor, being converted to water in the process.
