Cytochromes c are haemoproteins which carry out electron transfer in a wide variety of biological systems, necessitating different kinds of cytochrome c to fulfill different biological roles. The evolutionary relationship between cytochromes c and their host organisms are described, as well as their structural, spectroscopic and redox properties, including both electron-transfer rates and redox potentials. The treatment is aimed at the non-specialist so that both the techniques described and their application to cytochromes c can be understood. All classes of cytochrome c are dealt with to provide a comprehensive account of the field. No other text provides such a broad survey. Similar to the earlier volume "Cytochromes c: Biological Aspects" which deals with the classification, biosynthesis and biological role of cytochromes c, the present book is aimed at research workers and advanced students.

Cytochrome c fulfills a central role in biological electron transport. This book draws together information from diverse disciplines in order to provide a common base for further research. The comprehensive treatment of this subject does not neglect to show the diversity of biological respirations and photosyntheses. But it also defines their unifying principles. This overview presents the evolutionary relatedness in bioenergetic systems. Such systems are discussed at the experimental level with emphasis on the interpretation of results and the methodological approaches used. No other text provides a broad survey of this central area of biology. Researchers on cytochrome c are presented with information on the impact and importance of other disciplines on their area of investigation. Advanced students gain a balanced account of biological electron transport and will be encouraged to seek new directions of research.

Cytochromes P450 (CYPs) comprise a large superfamily of proteins that are of central importance in the detoxification or activation of a tremendous number of natural and synthetic hydrophobic xenobiotics, including many therapeutic drugs, chemical carcinogens and environmental pollutants. CYPs are important in mediating interactions between an organism and its chemical environment and in the regulation of physiological processes. Cytochrome P450 Protocols, Third Edition focuses on high-throughput methods for the simultaneous analysis of multiple CYPs, substrates or ligands. Although the emphasis is on CYPs of mammalian origin, it reflects an increasing interest in CYPs of bacterial species. Also included are chapters on cytochrome P450 reductase (the redox partner of CYPs) and the flavin-containing monooxygenases (FMOs), and metabolomic and lipidomic approaches for identification of endogenous substrates of CYPs (‘de-orphanizing’ CYP substrates). Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Cytochrome P450 Protocols, Third Edition provides a wide range of techniques accessible to researchers in fields as diverse as biochemistry, molecular biology, pharmacology, toxicology, environmental biology and genetics.

Major advances have been made in recent years in clarifying the molecular properties of the cytochrome P-450 system. These advances stem, in practical terms, from the generally recognized importance of cytochrome P-450 in the metabolism of drugs and in the bioactivation of xenobiotics to toxic products. The fascinating multiplicity and differential regulation of cytochrome P-450 isozymes, and their ability to catalyze extraordinarily difficult chemical transformations, have independently drawn many chemists and biochemists into the P-450 circle. Progress in the field, from a technical point of view, has been propelled by the de velopment of reliable procedures for the purification of membrane-bound enzymes, by the growing repertoire of molecular biological techniques, and by the development of chemical models that mimic the catalytic action of P-450. As a result, our understanding of the P-450 system is moving from the descriptive, pharmacological level into the tangible realm of atomic detail. The rapid progress and multidisciplinary character of the cytochrome P-450 field, which cuts across the lines that traditionally divide disciplines as diverse as inorganic chemistry and genetics, have created a need for an up-to-date evaluation of the advances that have been made. It is hoped that this book, with its molecular focus on the cytochrome P-450 system, will alleviate this need. The authors of the individual chapters have strived to emphasize recent results without sacrificing the background required to make their chapters comprehensible to informed nonspecialists.

This volume is based on the proceedings of an International Symposium on "Cytochrome Systems: Molecular Biology and Bioenergetics" that was held at Selva di Fasano near Bari, Italy, between April 7 and 11,1987. It contains papers covering the subjects discussed at the Symposium, contributed both by participants of the meeting and by some invited speakers who were not able to attend. The aim of the Symposium was to bring together experts in various rese arch strategies currently being applied to the study of cytochrome systems, including molecular genetics, protein chemistry, enzymology of electron transfer and protonmotive activity in energy-transducing biological mem branes. Because of the high degree of complexity of cytochrome systems and the increasing sophistication in recent years of the different experimen tal approaches, there has been a growing specialization - sometimes even a tendency to "over-specialization" - among scientists working in this field. This in itself seemed to justify a meeting where representatives of various disciplines could exchange their results and discuss their conclusions. In addition, and perhaps even more importantly, it was felt that meetings of this kind provide an opportunity for a "cross-fertilization" of approaches and ideas among representatives of various fields of science. The present meeting proved to be an ample illustration of the success of such an inter action.

From Cyclotrons to Cytochromes: Essays in Molecular Biology and Chemistry focuses on the uses of the cyclotron and radioactive isotopes in molecular biology and chemistry. The book includes a tribute to Martin Kamen, who played an important role in the development of biochemical sciences in the United States, particularly through his research on the cyclotron. The text also documents research on isotopes carried out at the Radiation Laboratory of the University of California at Berkeley during the 1930s, as well as the role of radioactive carbon in bacterial metabolism and experimental work on cytochromes. This volume is organized into six sections encompassing 54 chapters and begins with an overview of science and technology, and then discusses carbon-14 and its half-life. The next chapters discuss the chemistry and structure of cytochromes; the role of cytochromes and redox systems in photosynthesis; the biological aspects of phosphorylation and oxidation; and protein structure. The book also methodically explains the regulatory mechanisms and miscellaneous metabolic processes such as the metabolism of cyclic nucleotides and related compounds; biological functions of lactate dehydrogenase; and nucleotide excision repair of damaged DNA. The final chapter discusses the deamidation of asparagine and glutamine side chains when incorporated into polypeptide chains, with reference to the role of cryptic amidase active sites in catalyzing the process. This book is a valuable resource for biochemists and molecular biologists.
