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.

peroxidase

(pə-rŏk′sĭ-dās′, -dāz′)
n.
Any of a group of enzymes that occur especially in plant cells and catalyze the oxidation of a substance by a peroxide.

peroxidase

an enzyme that catalyses the oxidation of various substances by peroxides.
