Abstract

The kinetics of the RuIII-(edta) (edta4− = ethylenediaminetetraacetate) catalyzed oxidation of L-arginine by H2O2 mimicking the action of nitric oxide synthases (NOSs) has been studied spectrophotometrically. The time course of the reaction of [RuV(edta)O]− with L-arginine was followed at 390 nm under catalytic turn-over conditions. Formation of NO in the reacting system has been confirmed with an isolated nitric oxide free radical analyzer. A detailed reaction mechanism in agreement with the spectral and kinetic data is presented.
