Heme proteins play a major role in various biological functions, such as oxygen sensing,
electron transport, signal transduction, and antioxidant defense enzymes. Most of these …

Five procedures are presented for the determination of hydrogen peroxide and organic
hydroperoxides (including organic peroxyacids) at concentrations of 1–10 μM in aqueous …

A brief description is made of properties of a wide variety of peroxidases which illustrates
differences as well as similarities. The article begins with monoheme enzymes and ends …

A peroxidase modelsystem employing various model hemin compounds as catalysts, m-
chloroperbenzoic acid as the principal oxidant, and tri-fert-butylphenol as the substrate is …

The reaction of hydrogen peroxide with 5, 10, 15, 20-tetrakis (2, 6-dimethyl-3-
sulfonatophenyl) porphinato-iron (III) hydrate [(P) FeIII (H2O)] has been investigated in water …

The oxidation of ferrihaems by H2O2 was studied as a model for haem catabolism. Rates of
ferrihaem oxidation were evaluated by using a new computer-based method that measures …

The kinetics of formation of the dominant intermediate (CII) formed between hemin and
H2O2 has been studied by the stopped‐flow method. CII is preceded by a precursor (CI) for …

The group of proteins generally referred to under the umbrella term" hemoproteins" utilize
iron porphyrin (usually ferriprotoporphyrin IX [protoferriheme], or a close chemical relative …

The reaction of hydrogen peroxide with protohemin has been examined in aqueous solution
(pH 5—10) with potassium ferrocyanide as a substrate. Kinetic studies were carried out in …

The interaction of hydrogen peroxide, ascorbate and microperoxidase-11 (MP11), a
ferriheme undecapeptide derived from cytochrome c, has been investigated using …
