THIS BOOK collects together papers given at a NATO Advanced Research Workshop held at Il Ciocco (Lucca), Italy, from the 9th to the 15th April, 1989. It sets out to present the current state of understanding of the principles governing the way fluxes and concentrations are maintained and controlled in metabolic systems. Although this is a topic that has held the interest of biochemists for many years, it is only quite recently that the methods of analysing the kinetics of multi-enzyme pathways developed over the past two decades have come to be widely discussed or applied experimentally. Many biochemists remain sceptical that the new methods offer a real advance (except in complexity) over the landmark discoveries of the 1950s and 1960s relating to inhibition of enzymes at branch-points by the end products of metabolic pathways, and the interpretation of allosteric effects and cooperativity. Even those who have become convinced that the classical ideas provide only the starting point for understanding metabolic control have been by no means unanimous in their assess ment of the direction in which one should advance. In this book we have tried to include all of the current points of view, including the view that the classical theories tell us all that we need to know. We have not seen it as our role as editors to paper over the cracks that exist and to pretend that we can speak to the world with one voice.

Fully understanding the complex process of the integration and control of metabolism in cellular organisms requires knowledge in several fundamental concepts. Drawing on nearly two decades of innovative studies, Doctors Naa Adamafio, Laud Okine, and Jonathan Adjimani specifically target the intricacies of metabolism and provide a comprehensive approach to the subject. The text is divided into three essential areas of study: Fundamentals of metabolic control-dealing with the basic concepts of metabolic control and the role played by regulatory enzymes Control of cellular metabolism-including the regulation of the metabolism of major biomolecules, such as carbohydrates, lipids, and compounds containing nitrogen The integration of metabolism-observing the methods in which various metabolic pathways within and between tissues and organs are integrated Whether you are an undergraduate student in biochemistry, a medical student in your preclinical years, or a teacher in the subject area, Integration and Control of Metabolism is a valuable medical resource.

Although phosphorylation of proteins on tyrosine is relatively rare compared to phosphorylation on serine or threonine residues, the past two decades of research into PTP function have led to a great appreciation of the critical role PTPs have in regulating basic cellular processes. Among these important roles is the regulation of cellular signaling pathways related to metabolism. This volume contains chapters which highlight many aspects of PTP function in the context of metabolism. Given the growing obesity and diabetes epidemics in the United States and throughout the world, the desire to identify possible therapeutic targets for treatment of these diseases is a high priority. In many ways, PTPs may be attractive drug targets since they are amenable to targeting with small molecules; however many challenges abound in making PTP inhibitors.

During the last two decades, the prevalence of obesity has dramatically increased in western and westernized societies. Its devastating health consequences include hypertension, cardiovascular diseases, or diabetes and make obesity the second leading cause of unnecessary deaths in the USA. As a consequence, obesity has a strong negative impact on the public health care systems. Recently emerging scienti?c insight has helped understanding obesity as a complex chronic disease with multiple causes. A multileveled gene–environment interaction appears to involve a substantial number of susceptibility genes, as well as associations with low physical activity levels and intake of high-calorie, low-cost, foods. Unfor- nately, therapeutic options to prevent or cure this disease are extremely limited, posing an extraordinary challenge for today’s biomedical research community. Obesity results from imbalanced energy metabolism leading to lipid storage. Only detailed understanding of the multiple molecular underpinnings of energy metabolism can provide the basis for future therapeutic options. Numerous aspects of obesity are currently studied, including the essential role of neural and endocrine control circuits, adaptive responses of catabolic and anabolic pathways, metabolic fuel sensors, regulation of appetite and satiation, sensory information processing, transcriptional control of metabolic processes, and the endocrine role of adipose tissue. These studies are predominantly fuelled by basic research on mammalian models or clinical studies, but these ?ndings were paralleled by important insights, which have emerged from studying invertebrate models.

The aim of this book is to show how supramolecular complexity of cell organization can dramatically alter the functions of individual macromolecules within a cell. The emergence of new functions which appear as a consequence of supramolecular complexity, is explained in terms of physical chemistry. The book is interdisciplinary, at the border between cell biochemistry, physics and physical chemistry. This interdisciplinarity does not result in the use of physical techniques but from the use of physical concepts to study biological problems. In the domain of complexity studies, most works are purely theoretical or based on computer simulation. The present book is partly theoretical, partly experimental and theory is always based on experimental results. Moreover, the book encompasses in a unified manner the dynamic aspects of many different biological fields ranging from dynamics to pattern emergence in a young embryo. The volume puts emphasis on dynamic physical studies of biological events. It also develops, in a unified perspective, this new interdisciplinary approach of various important problems of cell biology and chemistry, ranging from enzyme dynamics to pattern formation during embryo development, thus paving the way to what may become a central issue of future biology.

In mammals, a robust physiologic system acts to maintain relative constancy of weight. A key element of this system is leptin. The nature of this "brain-somatic" cross talk is as yet poorly understood, but it is likely to have important implications for the pathophysiology and treatment of obesity, diabetes and other metabolic disorders.

Energy Metabolism and the Regulation of Metabolic Processes in Mitochondria contains papers presented at the 1972 symposium on metabolic regulation, held at the University of Nebraska Medical School in Omaha, Nebraska. The contributors provide alternative views and ideas in some aspects of metabolic regulation directly concerned with mitochondrial function. Separating 16 papers into chapters, this book first discusses the general aspects of control of the biological energy regulation and the kinetic and thermodynamic control of mitochondrial electron transport and energy coupling. It then covers significant topics on citric acid cycle, including its replenishment and depletion; anion transport and regulation; dynamics and substrate compartmentation; and feedback control. Other chapters examine the mechanisms of gluconeogenesis, lipogenesis, redox reaction, and phosphorylation in the mitochondria. Discussions on hormonal regulation of selected enzyme system directly related to mitochondrial function are provided in the concluding chapters. Biochemists, physiologists, pharmacologists, physicians, researchers, and all others interested in the concepts of mitochondrial function will find this book of great value.

Two decades have passed since the mechanisms of protein synthesis became well enough understood to permit the genetic modification oforganisms. An impressive amount of new knowledge has emerged from the new technology, but much ofthe promise of20years ago has notyet been fulfilled. In biotechnology, efforts to increase the yields of commercially valuable metabolites have been less successful than ex pected, and when they have succeeded it has often been as much from selective breeding as from new methods. The cell is more complicated than what is presented in the classical teaching of biochemistry, it contains more structure than was dreamed of 20 years ago, and the behaviour ofany systemofenzymes is more elaborate than can be explained in terms ofa single supposedly rate-limiting enzyme. Even if classical enzymology and meta bolism may have seemed rather unfashionable during the rise ofmolecular biology, they remain central to any modification ofthe metabolic behaviour oforganisms. As such modification is essential in much ofbiotechnology and drug development, bio technologists can only ignore these topics at their peril.

The ability to control the rates of metabolic processes in response to changes in the internal or external environment is an indispensable attribute of living cells that must have arisen with life’s origin. This adaptability is necessary for conserving the stability of the intracellular environment which is, in turn, essential for maintaining an efficient functional state. The advent of genomics, proteomics, and metabolomics has revolutionised the study of plant development and is now having a significant impact on the study of plant metabolism and its control. In the last few years, significant advances have been made, with the elucidation of enzyme gene families and the identification of new proteinaceous and allosteric regulators. The first part of this volume is devoted to generic aspects of metabolic control, with chapters on the key control points in pathways. Part Two considers the control of specific pathways, with detailed descriptions (including structures) and discussions of the regulation of these pathways, particularly in terms of the enzymology. The book is directed at researchers and professionals in plant biochemistry, physiology, molecular biology and cell biology.

As widely spread health problems related to over-and undernutrition have grown nowadays to an epidemic extent and even prevail over infectious diseases, a better knowledge of the metabolic basis of clinical nutrition has become essential. The extremes of the nutritional spectrum, undernutrition and obesity, are no longer considered as isolated opposites with different effects on separate risk groups, but paradoxically prove to be interacting in a setting of rapidly changing lifestyles, as is presently the case worldwide. Recurring issues such as insulin resistance, changes in intermediary metabolism, fluid and electrolyte physiology, genetic and non-genetic inheritance are highlighted, as well as the biological linkage between maternal undernutrition and the development of obesity, diabetes and cardiovascular disease in later life. The problems at stake present a new and enormous challenge for future healthcare policies and, therefore, are better tackled today. This book will be an interesting source of knowledge for internists, family physicians, pediatricians, dieticians, endocrinologists, gastroenterologists, and public health officers.

This SpringerBrief on Spx reviews the investigations that led to the discovery of Spx and its orthologs and ties together the results of various studies that have explored the function and control of spx in Gram-positive organisms. Spx of Bacillus subtilis has been extensively studied, but very little has been published about it. This book incorporates a number of studies that have been conducted in other Gram positive bacteria, which examined the role of Spx orthologs in stress response, bacterial development and virulence. The book contains an overview that will introduce the protein and its orthologous forms, its association with RNA polymerase, the species of Gram-positive bacteria in which it is found, and the conditions in which it is abundant and active. Spx is a member of a large group of proteins belonging to the ArsC/Spx protein family, so the review touches upon the bioinformatic support for the protein family composition and its meaning with regard to protein structure/function. ​

Endocrinology II concerns the actions of hormones in insects, complementing Volume 7 which is concerned with the production and chemistry of insect hormones. While the preceding volume is directed mainly towards the insect endocrinologist, this volume has much of intrinsic interest to the general physiologist. It deals with the regulation of metabolism, reproduction, cuticle properties, and certain aspects of behaviour from a systems point of view and amply documents how hormones have provided basic insights into the functioning of such systems. Interference in endocrine regulation could provide future systems for insect control and this volume will provide the foundation on which the future formulation of these strategies is based. More information on diverse aspects of insect hormone action is brought together here than in any previous single work and this volume will therefore be a valuable reference source for many years to come.
