Horseradish peroxidase (HRP) was oxidized by IrCl6(2-) to a mixture of compounds I and II, the rate of oxidation and the ratio of the mixture being greatly affected by pH (Hayashi & Yamazaki, 1979). Oxidation of HRP by IrCl6(2-) in

One-electron oxidation of phenol, 2,4,6-trimethylphenol, and 2,6-dimethylphenol by [IrCl(6)](2-) in aqueous solution has a simple pH dependence, indicating slow bimolecular oxidation of ArOH and faster oxidation of ArO(-). H/D kinetic isotope effects as large as 3.5 for oxidation of ArOH

Unlike superoxide dismutases (SODs), superoxide reductases (SORs) eliminate superoxide anion (O(2)(•-)) not through its dismutation, but via reduction to hydrogen peroxide (H(2)O(2)) in the presence of an electron donor. The microaerobic protist Giardia intestinalis, responsible for a common intestinal disease

Two gel electrophoretic methods are described for detection of 7, 8-dihydro-8-oxoguanine and 7,8-dihydro-8-oxoadenine based on their further oxidation with one-electron oxidants including IrCl62-and IrBr62-. The products of nucleobase oxidation lead to enhanced piperidine-sensitive cleavage and to highly visible stop points

Biochemistry, 19(25), 5795-5799 (1980-12-09)
Zinc-substituted horseradish peroxidase is oxidized by K2IrCl6 to a characteristic state which retains one oxidizing equivalent more than the zinc peroxidase. The oxidized enzyme gives an optical absorption spectrum similar to that of compound I of peroxidase and catalase, and
