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.
Plant Peroxidases: Biochemistry and Physiology recoge los últimos avances en el campo de las peroxidasas vegetales. Las peroxidasas son un grupo de enzimas que se encuentran ampliamente distribuidas en toda la escala filogenética y catalizan la oxidación de un amplio número de sustratos orgánicos e inorgánicos, utilizando el poder oxidante del peróxido de hidrógeno. Además de su interés académico y fisiológico, estas enzimas son ampliamente utilizadas en laboratorios clínicos y en la industria. El presente libro consta de 47 artículos de investigaciónen en los que se tratan diversos aspectos de las peroxidasas como su estructura, enzimología genética, fisiología, localización y aplicaciones. Las aportaciones a este libro han sido realizadas por especialistas de todo el mundo que se reunieron en Murcia en el año 2002 durante el Congreso titulado VI International Plant Peroxidase Symposium
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.

This book provides an overview of antioxidants and antioxidant enzymes and their role in the mechanisms of signaling and cellular tolerance under stress in plant systems. Major reactive oxygen species (ROS)-scavenging/modulating enzymes include the superoxide dismutase (SOD) that dismutates O2 into H2O2, which is followed by the coordinated action of a set of enzymes including catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX) and peroxiredoxins (Prx) that remove H2O2. In addition to the ROS scavenging enzymes, a number of other enzymes are found in various subcellular compartments, which are involved in maintaining such redox homeostasis either by directly scavenging particular ROS and ROS-byproducts or by replenishing antioxidants. In that respect, these enzymes can be also considered antioxidants. Such enzymes include monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), glutathione reductase (GR), alternative oxidases (AOXs), peroxidases (PODs) and glutathione S-transferases (GSTs). Some non-enzymatic antioxidants, such as ascorbic acid (vitamin C), carotenes (provitamin A), tocopherols (vitamin E), and glutathione (GSH), work in concert with antioxidant enzymes to sustain an intracellular steady-state level of ROS that promotes plant growth, development, cell cycles and hormone signaling, and reinforces the responses to abiotic and biotic environmental stressors. Offering a unique compilation of information on antioxidants and antioxidant enzymes, this is a valuable resource for advanced students and researchers working on plant biochemistry, physiology, biotechnology, and signaling in cell organelles, and those specializing in plant enzyme technology.
The Peroxidases in Chemistry and Biology series provides up-to-date information on a wide range of developments in the field of Peroxidases, methods and applications. This is Volume 1 originally published in 1990.
Plant pathology embraces all aspects of biological and scientific activity which are concerned with understanding the complex phenomena of diseases in plants. Physiological plant pathology represents those specialities within plant pathology which focus on the physiological and biochemical activities of pathogens and on the response of host plant tissues. Today there is an increasing recognition on the part of the scientific agri cultural community that only through a deeper and more fundamental under standing of all the interacting components of the agricultural biota can we expect to improve our capabilities of feeding an expanding world population. It is in this context that physiological plant pathology has assumed new significance within the broader field of plant pathology. No longer are studies on the biochemistry and physiology of pathogens and pathogenesis merely isolated academic exercises; rather, a substantial coherent body of knowledge is accumulating upon which our understanding of the process of disease developmen t and host resistance is being founded. It is from these foundations of knowledge that ultimately new insights into the control of plant diseases may be expected to grow. It seems appropriate, therefore, that at regular intervals those involved in the various subspecialities encompassing the broadest aspects of physiological plant pathology reassess the contributions within the particular specialities in the light of new knowledge and technologies for the purpose of articulating new and productive directions for the future.
SINGLE SOURCE GUIDE TO PEROXIDASES AND CATALASES Reflecting the important historical discoveries and exciting research in the field in recent years, Peroxidases and Catalases: Biochemistry, Biophysics, Biotechnology and Physiology provides a much-needed systematic, up-to-date treatment of peroxidases and catalases. From the structure and properties of the various superfamilies to current applications of peroxidases, the book consolidates vast amounts of information previously scattered in the professional literature, covering all aspects of these ubiquitous enzymes that act on a variety of substances and processes in living systems—their properties, reactions, crystal structures, cloning, and more. Considering the subject from both theoretical and applied perspectives, Peroxidases and Catalases offers a critical review of the literature and detailed discussions of the most current research. Chapters cover: The background and history of peroxidases and catalases Plant, fungal, and bacterial peroxidase superfamilies and their organization Mammalian peroxidases including medical and physiological roles Spectroscopic and theoretical techniques for studying peroxidases highlighting the contributions of physicists and physical/theoretical chemists Heme peroxidases, catalases, and other peroxidases such as vanadium and selenium peroxidase Relevant plant and animal physiology This one-stop reference is a vital reference for biochemists, biologists, biochemical engineers, physiologists, environmental and pharmaceutical researchers, and others interested in the study and use of peroxidases and catalases.
