Adp Ribosylation Reactions

This monograph is dedicated to one of the discoverers of poly(ADP ribose), Professor Paul Mandel, from the Centre de Neurochimie in Strasbourg. We would like to congratulate him for his distinguished contributions to the field of poly(ADP-ribosyl)ation and express our gratitude for his support in the last years and particularly for his encouragement for the organization of this meeting. Poly(ADP-ribose) was discovered more than 25 years ago. Since then, excellent progress has been made on the study of the mechanisms of poly(ADP ribose) reaction. The last five years have been particularly exciting since the development of various molecular biology techniques has revealed the complex nature of this multifunctional enzyme. Looking at the contributions presented at this meeting, it becomes obvious that more work at the molecular level is needed. Most likely, these experiments will shed some light on the functions of poly(ADP-ribose), but further ~iophysical studies will still be required to fully understand this complex enzymatic system.

ADP-Ribosylation Reactions: Biology and Medicine deals with the biochemical and physiological aspects of poly(ADP-ribose) and ADP-ribosylation of proteins. Topics covered range from pyridine nucleotide metabolism and ADP-ribosylation to the structure and properties of poly(ADP-ribose), along with acceptor proteins of poly(ADP-ribose). ADP-ribosyl protein linkages and poly(ADP-ribose) synthetase are also discussed. Comprised of 39 chapters, this book begins with a historical background on the discovery of poly(ADP-ribose) and the significance of poly- and mono(ADP-ribosyl)ation reactions in molecular biology. The next section explores the role of ADP-ribosylation in NAD metabolism, paying particular attention to poly(ADP-ribose) synthetase-DNA interaction and the link between chromatin structure and poly(ADP-ribosyl)ation. Subsequent chapters focus on subfractions and subcellular distribution of mono(ADP-ribosyl) proteins in eukaryotic cells; polyadenylylation and ADP-ribosylation of reovirus proteins; poly(ADP-ribose) synthesis in plants; and immunohistochemistry of poly(ADP-ribose). The final chapter analyzes the ADP-ribosylation activity of toxin A and exoenzyme S in Pseudomonas aeruginosa. This monograph is written for students, practitioners, and researchers in fields such as molecular biology, medical chemistry, and biochemistry.

This special issue of Molecular and Cellular Biochemistry contains twenty-two selected research papers and reviews from a total of one hundred and ten presentations given at the 12th International Symposium on ADP-ribosylation Reactions: From Bacterial Pathogenesis to Cancer, held in Cancun, Mexico, May 10-14, 1997. The Symposium was hosted by the Sociedad Mexicana de Bioquimica and was sponsored by the University of North Texas Health Science Center, Fort Worth, TX, USA. This volume provides a state-of-the-art source of information for basic scientists and clinicians who are interested in the molecular, biochemical, and cellular aspects of protein-(ADP-ribose) transfer reactions in human health and disease.

This book provides an update on recent advances in the field of ADP ribosylation reactions. The individual chapters represent the synopses of contributions which were presented at the Seventh International Symposium on ADP-Ribosylation Reactions, held in Vitznau, Switzer land, from September 23 to 27, 1984. This volume covers new devel opments in the field since the last meeting was held on this topic in 1982, in Tokyo. Therefore, the present text is not meant to form a comprehensive account of a specialized research area, but encompasses a collection of state-of-the-art reports from the vast majority of laboratories currently involved in ADP-ribosylation work. For the sake of rapid publication, the editorial policy was to ensure easy accessibility of information contained in individual articles rather than to provide elaborate cross references or reference to work published prior to 1982. However, a detailed subject index will help the reader find complementary information. The enzymes of ADP-ribose metabolism have not yet acquired universally acceptable trivial names and the Enzyme Commission has not yet defmitely decided on formal appellations. Consequently, a variety of names for the nuclear enzyme appear in this book, including nuc1ear(ADP-ribosyl)transferase, poly(ADP-ribose) polymerase, or synthetase or synthase. Hopefully, a common convention will soon be established. The Seventh International Symposium on ADP-Ribosylation Reac tions was only possible because of the generous support which we have been given by our sponsors, listed below.

Current interest in NAD (Nicotinamide adenine dinucleotide) in biological systems focuses on its role in ADP-ribose transfer reactions. These appear to be fundamentally involved in the regulation of many physiological processes. The contributions in this monograph thus represent the range of research in the very active investigation of niacin metabolism. The major topics covered are: ??? - Enzymology of ADP-Ribosylation - ADP-Ribosylation and Chromatin Function - Carcinogenesis and Differentiation - NAD Metabolism and Chemotherapy - ADP-Ribosylation and Signal Transduction - Molecular Genetic Approaches to ADP-Ribosylation

In 1966, a paper entitled "On the formation of a novel adenylylic compound by enzymatic extracts of liver nuclei" from Paul Mandel's laboratory in Strasbourg, France, planted the seed for a rapidly growing new field of biological research focusing on ADP-ribosylation reactions. The development of this field over the past 2 decades reflects very much a modern trend of biological research. As more detailed knowledge accumulates, enigmatic phenomena turn into concepts which create their own enigmata. This process tends to favor the development of multiple, seemingly disconnected, research lines until simplicity emerges from chaos and unifying concepts substitute for controversy. It appears that the field of ADP-ribosylation reactions has not yet attained this latter stage. For example, with the identification of two different classes of ADP-ribosylation reactions, i.e., mono-ADP-ribosyla­ tion and poly-ADP-ribosylation reactions, the field split very early into two separate branches of research. With the present volume, we have divided the task of reviewing these two classes of ADP­ ribosylation accordingly, although their coexistence in eukaryotes may involve a closer functional linkage than hitherto recognized.
