title: [Kinetics of the catalytic oxidation of catechol in aqueous solutions of ceruloplasmin in the presence of Fe3+].
abstract: The kinetics of oxidation of catechol in aqueous solutions containing ceruloplasmin and Fe3+, were studied. It was found that Fe3+ at low concentrations accelerate the reaction. The inhibiting effect of high concentrations of Fe3+ is due to the formation of catalytically inactive enzyme complexes with catechol oxidation products. A mechanism of this process is proposed.
