Oxidation of 2-nitropropane by horseradish peroxidase. Involvement of hydrogen peroxide and of superoxide in the reaction mechanism.

Abstract

Incubation of aqueous solutions of 2-nitropropane in air causes a slow oxidation reaction that generates H(2)O(2). Purified horseradish peroxidase catalyses the oxidation of such preincubated 2-nitropropane solutions according to the equation: [Formula: see text] The pH optimum is 4.5 and K(m) for 2-nitropropane is 16mm. Other nitroalkanes or nitro… (More)
