Mammalian heme peroxidase enzymes play a critical role in innate immune responses and disease prevention. The formation of potent chemical oxidants is essential to this protective physiologic activity in immunity. Although highly beneficial in the context of immune defense, it is now well established that peroxidases and their overproduction of oxidants contribute to the initiation and persistence of many chronic inflammatory conditions in the cardiovascular, neurologic, respiratory, renal, and gastrointestinal systems. Peroxidasins, a protein family related to heme peroxidases, play a novel role in tissue biogenesis and matrix assembly, which are also attracting attention in different pathological contexts. Given the diverse roles of mammalian heme peroxidases and the breadth and incidence of pathologies associated with these enzymes, there has been significant interest in modulating peroxidase activity as a therapeutic strategy. This book highlights recent developments in our understanding of the chemistry, biochemistry and biological roles of mammalian peroxidases and their associated oxidants, their involvement in both innate immunity and chronic inflammatory disease in a variety of end organs, and potential therapeutic approaches to modulate and prevent damaging reactions. Key Features Structure and biosynthesis of mammalian peroxidases Reactivity of hypohalous acids with biological substrates Peroxidases in innate immunity Peroxidases in human pathology Modulation of peroxidase-induced biological damage

The last systematic description of heme peroxidases was published in 1999 by Brian Dunford, from the University of Alberta in Canada. The book Heme per- idases covers discussion on three-dimensional structure, reaction mechanism, kinetics, and spectral properties of representative enzymes from bacterial, plant, fungal, and animal origin. Since 1999, vast information on basic but also applied aspects of heme peroxidases has been generated. We believe fusion of these two aspects will bene?t research of those dedicated to development of biocatalytic process. The aim of this book is to present recent advances on basic aspects such as evolution, structure–function relation, and catalytic mechanism, as well as applied aspects, such as bioreactor and protein engineering, in order to provide the tools for rational design of enhanced biocatalysts and biocatalytic processes. The book does not include an exhaustive listing of references but rather a selected collection to enrich discussion and to allow envisioning future directions for research. This book is organized in three parts. In Part I, current knowledge of structure and mechanism of peroxidases is covered. From the molecular phylogeny, going through the in?uence of structural factors over oxidative ability to the molecular mechanism of catalysis, the authors intend to provide an understanding of per- idases at the molecular level. The understanding of the fundamental behavior of peroxidases will allow further adequation, design, and/or optimization of pero- dase-based catalysis to a particular process. In Part II, research on potential applications of peroxidases in several ?elds is presented and discussed.

This monograph describes many applications of peroxidase-based biocatalysis in the biotechnology industry. The need for such a book emerges from the considerable amount of new data regarding the phylogeny, reaction mechanisms, thermodynamic characterization and structural features of fungal and plant heme peroxidases that has been generated in the past 10 years, since the last specialized book on peroxidases was published. The aim of this book is to present recent advances on such basic aspects as evolution, structure-function relation and catalytic mechanism as well as applied aspects, such as bioreactor and protein engineering, to provide the tools for rational design of enhanced biocatalysts and biocatalytic processes.

Heme peroxidises catalyse the H2O2-dependent oxidation of substrates in a two-step process, through formation of two oxy-ferryl intermediates known as Compound I and Compound II. Despite the considerable effort worldwide, important aspects about the reactivity of these enzymes are still to be clarified. Amongst all, the determination of the nature of the Fe-O bond in the oxy-ferryl intermediates, as well as the mechanism by which protons are delivered to the oxy-ferryl species during turnover, are of highest relevance. In this thesis, high resolution crystal structures of both Compound I and Compound II intermediates in two heme peroxidases, cytochrome c peroxidase (CcP) and ascorbate peroxidase (APX), are presented. In order to rule out the photoreduction arising from X-ray exposure during data collection, which causes alteration of ferryl intermediate structures, a multicrystal method has been employed. Results indicate that Compound I, with an Fe-O distance of 1.63 Å for CcP and 1.73 Å for APX, is consistent with an unprotonated oxy-ferryl species (FeIV-OH), whereas Compound II, with an Fe-O bond length of 1.83 Å and 1.84 Å for CcP and APX respectively, is consistent with a protonated oxy-ferryl species (FeIV-OH). Also presented in this thesis is the 2.40 Å structure of resting ferric CcP at room temperature obtained, for the first time, by neutron crystallography. This study allowed to establish the location of individual, exchangeable hydrogen atoms thus revealing the protonation states of several key active site residues in the distal (Arg48, Trp51, His52) and proximal (His163, Trp191, Asp235) heme regions. This information was used to revise the reaction mechanism of heme peroxidases and also to infer a possible delivery pathway of protons during turnover. All together, these data not only clarify long-standing inconsistencies on the nature of the oxy-ferryl species, but they also provide new insights into the reaction mechanism of heme peroxidases and provide important information which may apply to other categories of heme enzymes such as the cytochromes P450 and NO synthases.

The second of two relatively independent volumes on the chemistry and biology of peroxidases. Volumes 2 covers the peroxidases isolated from plants and microorganisms, and includes detailed discussions of some of the unique reactions catalyzed by these enzymes. Volume one covered the peroxidases isolated from animal sources, as well as the "pseudo- peroxidase activity" of prostaglandin H synthase and of myoglobin and hemoglobin. Acidic paper.
