This reference work focuses on the enzyme systems that participate in the metabolism of chemicals and other xenobiotics, with emphasis being placed on drug metabolism. Each chapter focuses on a specific enzyme system.

Structure and Function of Glutathione S-Transferases provides some of the latest information available on a variety of structural and functional components of glutathione S-transferases, a family of isozymes involved in many endogenous and exogenous functions in cells. Molecular studies presented in the book focus on the regulation of these enzymes and identify important response elements. X-ray crystallographic structures show detailed information on the structural aspects of these proteins. Metabolism of a number of carcinogens and drugs is covered in detail, and the role that these enzymes play in governing drug resistance at the preclinical and clinical levels is discussed. The book will be excellent for biochemists, pharmacologists, oncologists, experimental therapeutic specialists, and others interested in glutathione S-transferases.

Focuses on particular aspects of the so-called Phase II of drug detoxication, which has important ramifications for endogenous metabolism and nutrition. This volume on glutathione transferases and gamma-glutamyl transpeptidases serves to bring together methods and concepts in a rapidly developing field of cell and systems biology.

This is the only book of its kind to provide an overview of the science of flavonoids in plants.

Herbicides and their Mechanisms of Action highlights issues in herbicide selectivity. Developed with the input of authors from both academia and industry, this volume delivers a comprehensive and up-to-date treatment of the operation of the selectivity mechanisms of herbicides. Even more, the book discusses real-world effects of herbicides, and the results herbicides bring to bear on the environment. The authors emphasize applied aspects of the subject and concentrate on the developments of the last decade, making the book both practical and timely. With the wide variety of herbicides now available for the selective control of weed growth, it is imperative that scientists acquire a detailed understanding of the scientific bases of these herbicides. Indeed, the most recently developed herbicides work by inhibiting the enzyme systems of specific herbs, thereby retarding the growth of those herbs. For maximum effectiveness it becomes crucial that the active ingredients of these herbicides be efficiently delivered on the desired targets. Providing a state-of-the-art appraisal of this important subject, Herbicides and their Mechanisms of Action is the ideal resource for virtually all researchers and professionals involved in the development, administration, and regulation of herbicides.

This volume contains the proceedings of the third in a series of conferences entitled, The International Symposium on Biological Reactive Intermediates. The first was held at the University of Turku in Finland, in 1975, the second at the University of Surrey in the United Kingdom, in 1980 and the most recent at the University of Maryland in the United States, in 1985. The significance of these conferences has been emphasized by the rapid growth of mechanistic toxicology over the last decade. These conferences were initially stimulated by the attempt to uncover the significance behind the observations that the toxicity of carcinogenic responses produced by many chemicals was associated with the observation that their metabolism led to the formation of chemcially reactive electrophiles which covalently bound to nucleophilic sites in cells such as proteins, nucleic acid or fats. Recently, newer concepts have arisen which have necessitated the expansion of subjects covered by the conference. For example, the application of newer knowledge of the role of active oxygen species in reactive metabolite formation, the concept of suicide substrates, examination of the function of glutathione in cells, application of immunological techniques and molecular biological probes to the solution of toxicological problems all had an impact on the study of the biological reactive intermediates.

This is the first serious attempt to synthesize all that became known of glutathione over the last three decades. The book contains an update of glutathione biosynthesis with special emphasis on its regulation in adaptive stress responses. Other chapters review glutathione transport systems and glutathione peroxidases and their differences in substrate specificities and localization. Further contributions center on the diversified roles of different glutathione-S-transferases and the roles of nitrosoglutathione and glutaredoxins - a subfamily of redoxins. The book closes with discussions of the analogous or homologous thiol metabolism in pathogens and the potential suitability of involved enzymes as drug targets. Key selling features: Summarizing the way glutathione is involved in stress responses Compiling the multiple ways glutathione affects inflammatory responses Disclosing how glutathione dampens programmed cell death such as ferroptosis Exploring the enigma of how enzymes accelerate glutathione-dependent processes Discussing how detoxification and redox regulation is mediated by glutathionylation Reviewing the ways glutaredoxins catalyze protein disulfide reduction Highlighting the medical impact of glutathione-related metabolic pathways Illustrating the role thiol metabolism of pathogens might play in drug discovery

This book discusses the primary functions of microtubule-associated proteins (MAPs) such as MAP2 and tau in neuronal morphogenesis, as well as relationships between neuronal differentiation and the expression of neuronal intermediate filaments (nestin, alpha internexin, and neurofilament triplet proteins). It emphasizes the importance of several cytoskeletal proteins for neuronal differentiation and morphogenesis, organelle transport, and synaptic functions. The book considers the involvement of tau MAPs in the formation of paired helical filaments in Alzheimer's disease, and it examines the mechanisms of organelle transports and molecular motors such as kinesin, braindynein, and kinesin superfamily proteins. Cytoskeletal proteins involved in synaptic formation and transmitter release and new synaptic junctional-associated proteins are explored as well.

This book describes the methods of analysis and determination of oxidants and oxidative stress in biological systems. Reviews and protocols on select methods of analysis of ROS, RNS, oxygen, redox status, and oxidative stress in biological systems are described in detail. It is an essential resource for both novices and experts in the field of oxidant and oxidative stress biology.

A guide to the chemical agents that protect plants from various environmental stressors Protective Chemical Agents in the Amelioration of Plant Abiotic Stress offers a guide to the diverse chemical agents that have the potential to mitigate different forms of abiotic stresses in plants. Edited by two experts on the topic, the book explores the role of novel chemicals and shows how using such unique chemical agents can tackle the oxidative damages caused by environmental stresses. Exogenous application of different chemical agents or chemical priming of seeds presents opportunities for crop stress management. The use of chemical compounds as protective agents has been found to improve plant tolerance significantly in various crop and non-crop species against a range of different individually applied abiotic stresses by regulating the endogenous levels of the protective agents within plants. This important book: Explores the efficacy of various chemical agents to eliminate abiotic stress Offers a groundbreaking look at the topic and reviews the most recent advances in the field Includes information from noted authorities on the subject Promises to benefit agriculture under stress conditions at the ground level Written for researchers, academicians, and scientists, Protective Chemical Agents in the Amelioration of Plant Abiotic Stress details the wide range of protective chemical agents, their applications, and their intricate biochemical and molecular mechanism of action within the plant systems during adverse situations.
