Background: Tyrosine-liganded hemoproteins typically are hydroperoxidases. They do not oxygenate their substrates. Results: In the presence of an oxygen donor, tyrosine-liganded allene oxide synthase stereospecifically oxygenated polyunsaturated fatty acids. Conclusion: A catalase-related enzyme can act as a monooxygenase. Significance: A catalase hemoprotein, with tyrosine as the proximal heme ligand, can exhibit monooxygenase activity, a property usually associated with a cysteinate heme ligand, as in cytochromes P450.

Abstract:The mechanisms of oxidation of a series of a-alkyl substituted mono and dimethoxylated benzyl alcohols catalysed by mesotetrakis(4-N-methylpyridynium)porphyrin iron (III) chloride (FeTMPyPCl) and meso-tetrakis(4-sulfonatophenyl)porphyrin iron (III) chloride (FeTSPPCl) in aqueous solution with KHSO 5 as oxygen atom donor and by meso-tetrakis(pentafluorophenyl)-porphyrin iron (III) chloride (FeTPFPPCl) in dichloromethane employing iodosylbenzene as oxidant have been investigated. In the highly polar aqueous medium an electron transfer mechanism is operating. With FeTMPyPCl, which is a much more efficient catalyst than FeTSPPCl due to the presence of stronger electron withdrawing substituents, formation of side-chain oxidation products accompanies generation of nuclear oxidation products. In the low polar solvent dichloromethane, two competing mechanism have been suggested: hydrogen atom transfer and formation of a complex between the active species iron-oxo porphyrin radical cation and the substrate.© Versita Warsaw and Springer-Verlag Berlin Heidelberg.
