Book Description
Heme peroxidases are widely distributed in biological systems and are involved in a wide range of processes essential for life. This book provides a comprehensive single source of information on the various aspects of heme peroxidase structure, function and mechanism of action. Chapters written and edited by worldwide experts span a range of heme peroxidases from plants, yeast, bacteria and mammals. Discussed functions of peroxidases range from cell wall synthesis, synthesis of prostaglandins, role in drug suppression of tuberculosis, and antibacterial activity. Included is a discussion of peroxidases that also act as catalases and oxygenases. Heme Peroxidases serves as an essential text for those working in industry and academia in biochemistry and metallobiology.

Book Description
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

Book Description
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.

Book Description
the refolding process is often the critical bottleneck in the production of high-value proteins, and recently acquired insights have yet to be translated into technological advantages. These proceedings bridge the gap between fundamental and applied studies, addressing such issues as in vivo protein folding, protein aggregation and inclusion body formation, elucidation of the folding pathway, characterization of folding intermediates, and practical considerations in protein renaturation. The symposium was part of the 199th ACS National Meeting, Boston, April 1990. Annotation copyrighted by Book News, Inc., Portland, OR

Book Description
This book describes in 13 chapters mechanisms of P450 used to monooxygenate substrates via the NAD(P)H/O2 pathway using its peroxidase and peroxygenase functions. P450 also utilizes peroxides, peracids, periodate and iodosobenzene to oxygenate substrates via the shunt pathway. Also described are mechanisms used in the oxidation of pharmaceuticals by CYP3A4; acyl- carbon cleavage by CYP17A1, CYP19A1 and CYP51A1; metabolism of tetrabromodiphenyl ethers and bile acids by CYP2B6 and CYP3A4; metabolism of ω-6 and ω-3 polyunsaturated fatty acids; H2O2-mediated peroxygenation of substrates using substrate misrecognition; P450 oxidative reactions using electrochemical methods; electron transfer to P450 by redox proteins; hydroxylation of 1,8-cineole by P450cin; and peroxygenation by unspecific peroxygenases using H2O2. The topics covered are relevant to P450 researchers, professors and students from a variety of disciplines ranging from pharmacology, toxicology and microbiology to chemistry.

Book Description
Caenorhabditis Elegans has been a popular model organism for biological research for over thirty years and has been used to investigate many aspects of animal development, for example apoptosis, the Hox genes, signal transduction pathways, and the development of the nervous system. It has recently taken on new importance with the publication of the entire genome sequence in 1998. The first chapter gives all the basic information on C. elegans required to use it: it's natural history, anatomy, life cycle, development, and evolution. Information on how to obtain, grow, and maintain C. elegans for use as a model system is given in Chapter 4. Chapters 2 and 3 describe the genome project and show how to use genome sequence information by searching the database for homologues using different search methods and then how to analyse the search data. The next chapter gives the essential practical details of transformation and common uses for the technique. Chapter 6 covers reverse genetics and describes strategies for gene inactivation that are known to work in C elegans: epigenetic inactivation and mutational germ line inactivation. Chapter 7 is designed to help the user analyse phenotype by microscopy and includes Normaski, fluorescence, 4-dimensional, and electron microscopy. Techniques for studying the neurobiology of C. elegans are given in chapter 8. Chapter 9 describes the three commonly used approaches for studying gene expression and Chapter 10 deals with the common methods of molecular biology essential for gene characterization. C. elegans is not the ideal organism for biochemical studies, but chapter 11 describes several procedures for producing biochemically useful quantities of pure tissues. The final chapter is about conventional genetics and details the standard procedures for selfing and crossing; mutagenesis and mutant screening; characterization of mutants; gene mapping; temperature-shift experiments and mosaic analysis. Caenorhabditis Elegans: A Practical Approach will therefore provide all the background information necessary for use of C. elegans as a model system.
