The inflammasome was first described in 2002 as a molecular complex activating proinflammatory caspases and therefore regulating the maturation and biological activities of cytokines such as IL-1 and IL-18. This finding was substantiated by the identification of several mutations in the cias1 gene, encoding the human NLRP3 protein, responsible for several autoinflammatory disorders such as the Muckle Wells syndrome. Since, the interest for this complex has constantly increased and several inflammasome complexes with different specificities have been described. These inflammasomes sense a wide variety of pathogens and danger signals and are key players in the inflammatory response. With the contributions of leading international experts in the field, this book provides an extensive overview of the current knowledge of inflammasome biology and their role in health and disease.

Ribonucleases are a ubiquitous and functionally diverse group of enzymes that have a common ability to cleave RNA. Either through scission of internal phosphodiesters, or removal of nucleotides from RNA 5' or 3' ends, ribonucleases perform essential roles in gene expression and regulation, genome replication and maintenance, host defense, stress response, and viral strategies of infection. Ribonucleases have also served as highly informative models to understand virtually every aspect of biomolecular structure and function. The fifteen chapters in this volume are written by recognized researchers in the field, and provide in-depth analyses of the major ribonuclease families. Particular focus is given to the relation of ribonuclease structure and mechanism to biological function, as well as ribonuclease dysfunction in certain disease states. Other topics include the evolutionary genetics and functional diversification of ribonucleases, engineered ribonucleases as anti-cancer agents, the mechanisms of action of artificial ribonucleases, and ribonucleases as models to understand protein folding and stability. This volume should serve as an essential reference for a broad range of researchers and educators with interests in RNA metabolism, enzymology, and gene regulation.

Obesity is a risk factor for breast cancer in older women. A number of adipose-derived and obesity-related factors have been shown to affect tumour cell growth. These include adipokines, insulin, IGF-1 and oestrogens. The majority of obesity-related postmenopausal breast cancers are oestrogen-dependent. Since the ovaries no longer produce oestrogens after menopause, and that circulating levels are negligible, it is evident that it is the oestrogens produced locally within the breast adipose that are responsible for the increased growth of breast cancer cells. Aromatase is the enzyme that converts androgens into oestrogens and its regulation is dependent on the activity of a number of tissue-specific promoters. Targeting oestrogen biosynthesis in obesity may be useful for the prevention of breast cancer. Aromatase inhibitors are efficacious at treating postmenopausal breast cancer and recent studies suggest that they may also be useful in the prevention setting. However, these compounds inhibit the catalytic activity of aromatase and as a consequence lead to a number of undesirable side-effects, including arthralgia and possible cognitive defects due to inhibition of aromatase in the bone and brain, respectively. Novel therapies, such as those employed to treat obesity-associated disease, including anti-diabetics, may prove successful at inhibiting aromatase specifically within the breast. This SpringerBrief will explore all of these issues in depth and the authors are in a unique position to write about this topic, having extensive experience in the field of aromatase research.

This book provides a review of the multitude of nucleic acid polymerases, including DNA and RNA polymerases from Archea, Bacteria and Eukaryota, mitochondrial and viral polymerases, and other specialized polymerases such as telomerase, template-independent terminal nucleotidyl transferase and RNA self-replication ribozyme. Although many books cover several different types of polymerases, no book so far has attempted to catalog all nucleic acid polymerases. The goal of this book is to be the top reference work for postgraduate students, postdocs, and principle investigators who study polymerases of all varieties. In other words, this book is for polymerase fans by polymerase fans.

Nucleic acid polymerases play a fundamental role in genome replication, maintenance, gene expression and regulation. Throughout evolution these enzymes have been pivotal in transforming life towards RNA self-replicating systems as well as into more stable DNA genomes. These enzymes are generally extremely efficient and accurate in RNA transcription and DNA replication and share common kinetic and structural features. How catalysis can be so amazingly fast without loss of specificity is a question that has intrigued researchers for over 60 years. Certain specialized polymerases that play a critical role in cellular metabolism are used for diverse biotechnological applications and are therefore an essential tool for research.

Yeasts are a versatile group of eukaryotic microorganisms, exhibiting heterogeneous nutritional profiles and an extraordinary ability to survive in a wide range of natural and man-associated ecosystems, including cold habitats. Cold-adapted yeasts inhabit numerous low-temperature environments where they are subjected to seasonal or permanent cold conditions. Hence, they have evolved a number of adaptation strategies with regard to growth and reproduction, metabolic activities, survival and protection. Due to their distinctive ability to thrive successfully at low and even subzero temperatures, cold-adapted yeasts are increasingly attracting attention in basic science and industry for their enormous biotechnological potential.

This book presents our current understanding of the diversity and ecology of cold-adapted yeasts in worldwide cold ecosystems, their adaptation strategies, and their biotechnological significance. Special emphasis is placed on the exploitation of cold-adapted yeasts as a source of cold-active enzymes and biopolymers, as well as their benefits for food microbiology, bioremediation and biocontrol. Further, aspects of food biodeterioration are considered.

Enzyme Technology is one the most promising disciplines in modern biotechnology. In this book, the applications of a wide variety of enzymes are highlighted. Current studies in enzyme technology are focused towards the discovery of novel enzymes (termed "bio-discovery" or "bio-prospecting") and the identification and elucidation of novel pathways of these novel enzymes with emphasis on their industrial relevance. With the development of molecular techniques and other bioinformatics tools, the time to integrate this subject with other fields in the life sciences has arrived. A rapid expansion of the knowledge base in the field of enzyme biotechnology has occurred over the past few years. Much of this expansion has been driven by the bio-discovery of many new enzymes from a wide range of environments, some extreme in nature, followed by subsequent protein (enzyme) engineering. These enzymes have found a wide range of applications, ranging from bioremediation, bio-monitoring, biosensor development, bioconversion to biofuels and other biotechnologically important value-added products. Hydrolases constitute a major component of the global annual revenue generated by industrial enzymes and the emphasis has therefore been placed on these enzymes and their applications. With the immense interest of researchers active in this area, this book will serve to provide information on current aspects in this field of study. In the current edition, the contributions of many diversified topics towards establishing new directions of research in the area of enzyme biotechnology are described. This book serves to provide a unique source of information to undergraduates, post graduates and doctoral courses in microbiology and biotechnology along with allied life sciences. The present edition of the book covers all important areas of enzyme biotechnology i.e. the wide variety of enzymes in the field of enzyme biotechnology and their industrial applications, new methods and state-of-the-art information on modern methods of enzyme discovery. This book will act as good resource on most of the current facets of enzyme technology for all students engaged in bioengineering and biotechnology.

For most of industrial applications, enzymes and cells have to be immobilized, via very simple and cost-effective protocols, in order to be re-used for very long periods of time.

With new chapters on protocols for immobilization of enzymes and cells which may be useful to greatly improve the functional properties of enzymes and cells. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Immobilization of Enzymes and Cells, Third Edition demonstrates simple and efficient protocols for the preparation, characterization, and utilization of immobilized enzymes and cells.

This book brings together lmportant work on the structure and function of the dehydrogenases requiring nicotinamide coenzymes. The structure and function of lactate dehydrogen- ase, alcohol dehydrogenase, and glyceraldehyde 3-phosphate dehydrogenase are compared. These are the relatively simple oligomeric dehydrogenases for which very extensive structural and mechanistic information is available. Kinetic studies are dealt with in general terms, with selected examples. Genetic and structural relationships revealed by primary structure are discussed. General features of the specificity of dehydrogen- ase reactions are described. The pyridine nucleotide - disulphide oxidoreductases exemplify a type of multicomponent enzyme complex. Lipoamide dehydrogenase, glutathione reductase, and thioredoxin reduct- ase are described and compared. The fatty acid synthesizing systems of some organ- isms are nonaggregated, whereas in other organisms they are multienzyme complexes containing, in animal tissues for example, two closely related multifunctional polypeptide chains. The dehydrogenase activities of the fatty acid syn- thesizing systems afford many points of interest, which are described and discussed. Hydroxymethylglutaryl-CoA reductase occupies a key position in the synthesis of isoprenoid compounds, including cholesterol. It probably occurs in all forms of life; in animal cells it is a microsomal enzyme. Its properties are reviewed.

Gamma-Glutamyl Transpeptidases ( -GTs) are members of the N-terminal nucleophile hydrolase superfamily, enzymes that cleave the -glutamyl amide bond of glutathione to liberate cysteinylglycine. The released -glutamyl group can be transferred to water (hydrolysis) or to amino acids or short peptides (transpeptidation). -GT plays a key role in the gamma glutamyl cycle by regulating the cellular levels of the antioxidant glutathione, hence it is a critical enzyme in maintaining cellular redox homeostasis. -GT is upregulated during inflammation and in several human tumors, and it is involved in many physiological disorders related to oxidative stress, such as Parkinson's disease and diabetes. Furthermore, this enzyme is used as a marker of liver disease and cancer. This book covers current knowledge about the structure-function relationship of -GTs and gives information about applications of -GTs in different fields ranging from clinical biochemistry to biotechnology and biomedicine.

Bioethanol has been recognized as a potential alternative to petroleum-derived transportation fuels. Even if cellulosic biomass is less expensive than corn and sugarcane, the higher costs for its conversion make the near-term price of cellulosic ethanol higher than that of corn ethanol and even more than that of sugarcane ethanol. Conventional process for bioethanol production from lignocellulose includes a chemical/physical pre-treatment of lignocellulose for lignin removal, mostly based on auto hydrolysis and acid hydrolysis, followed by saccharification of the free accessible cellulose portions of the biomass. The highest yields of fermentable sugars from cellulose portion are achieved by means of enzymatic hydrolysis, currently carried out using a mix of cellulases from the fungus Trichoderma reesei. Reduction of (hemi)cellulases production costs is strongly required to increase competitiveness of second generation bioethanol production. The final step is the fermentation of sugars obtained from saccharification, typically performed by the yeast Saccharomyces cerevisiae. The current process is optimized for 6-carbon sugars fermentation, since most of yeasts cannot ferment 5-carbon sugars. Thus, research is aimed at exploring new engineered yeasts abilities to co-ferment 5- and 6-carbon sugars. Among the main routes to advance cellulosic ethanol, consolidate bio-processing, namely direct conversion of biomass into ethanol by a genetically modified microbes, holds tremendous potential to reduce ethanol production costs. Finally, the use of all the components of lignocellulose to produce a large spectra of biobased products is another challenge for further improving competitiveness of second generation bioethanol production, developing a biorefinery.

This volume is concerned with the enzymes of the nervous system. Cerebral enzymes form the basis of the functional brain. They are needed for the control of the energetics of the nervous system, whether it be their release or their direction; for the elaboration of transmitters and for their destruction; for the synthesis, transport, and breakdown of all metabolites of the nervous system. They are indispensable for the control of the multitude of factors that govern our thinking and our behavior. They make it possible for us to comprehend what is taking place around us and perhaps to understand what may be in store for us. Enzymes are the stuff of life, and no living cell can be without them. They are the results of many millions of years of evolution, from the time when biological membranes first came into being and were folded to produce the first cells within which the earliest enzymes were wrought. Countless changes have taken place within them, so that, now, only those enzymes exist that play specific roles in the functions of the living cells of today. Those in the nervous system possess a mUltiple role: in the creation, maintenance, and ultimate breakdown of the component cells and in enabling consciousness, perception, memory, and thought to become possible. But though life may go on forever, the enzymes that make life possible will undergo the many changes involved in the evolutionary process.

Glycosyltransferases (GTs) are essential for the biosynthesis of complex glycoconjugates and are powerful tools to study the functions of complex glycans in health, development and disease. Complex glycoconjugates, such as glycoproteins, proteoglycans and glycolipids, are assembled by GTs which synthesize specific linkages between sugars or sugars and protein. This is in contrast to the non-specific or less specific chemical glycation reactions, transglycosylation and reverse glycosylation reactions. Glycosyltransferases: Methods and Protocols contains a wide range of studies, methods and protocols which form a solid basis for investigations of the role and mechanisms, biology and pathology involving GTs. Written in the successful Methods in Molecular Biology (TM) 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, Glycosyltransferases: Methods and Protocols is a vital contribution to glycobiology and glycopathology, and to applications of these enzymes in biotechnology and drug development. It will prove invaluable to students, postdoctoral fellows, and senior scientists carrying on research of GTs that has been intensified over the last years.

The invention of the polymerase chain reaction (PCR) won the Nobel Prize in Chemistry in 1994 and remains one of the most important scientific discoveries of the twentieth century. More than 50,000 researchers in the United States use PCR replication technology, and yet a book has not been published on the subject in more than ten years. In this book, Dr. Stephen A. Bustin, a world-renowned PCR expert, examines in detail the latest innovations and the overall impact of PCR on many areas of molecular research. The book contains personal reflections, opinions, and comments by leading authorities on the many applications of the PCR and how this technology has revolutionized their respective areas of interest. This book conveys the ways in which PCR has overcome many obstacles in life science and clinical research and also charts the PCR s development from time-consuming, low throughput, non-quantitative procedure to today s rapid, high throughput, quantitative super method.

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.

Is red wine good for you? And if so, why? How much? And what are the actual benefits? This addition to the SpringerBriefs in Cell Biology series thoroughly but succinctly answers these questions. It covers the biochemistry, health benefits and therapeutic potential of wine grapes. It begins with an overview of phytoalexin production in Vitis vinifera (Common Grape Vine), detailing the relationship of resveratrol to analogues such as pterostilbene, piceid and the viniferins (resveratrol oligomers). The discussion then turns to the hundreds of reports linking resveratrol and related grape vine polyphenols to various beneficial health effects especially cardio- and cerebro- vascular, metabolic, anti-inflammatory and more. Also addressed are the numerous intracellular mechanisms that have been shown to mediate the effects of these compounds in mammalian cells and tissues. Finally, the authors discuss aspects of polyphenol bioavailability and how this will influence choices taken for delivering these compounds as nutritional supplements. A brief chapter containing general conclusions and prospectus rounds out the information. ai

Whether the pursuit is commercially motivated or purely academic, engineering a novel biological catalyst is an enticing challenge. High-resolution protein structure analysis allows for rational alteration of enzyme function, yet many useful enzyme variants are the product of well-designed selection schemes or screening strategies. Enzyme Engineering: Methods and Protocols provides guidance to investigators wishing to create enzyme variants with desired properties. This detailed volume covers such topics as a simple method for generating site-specific mutations within bacterial chromosomes. It also highlights the engineering of two difference types of rare-cutting endonucleases that show great potential in gene therapy applications: The newest development is the emergence of TAL effector nucleases or TALENs. Chapters describe newly developed technologies in sufficient detail so that each method can be practiced in a standard molecular biology laboratory. Written in the successful Methods in Molecular Biology (TM) 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 Enzyme Engineering: Methods and Protocols will be valuable for scientists with a budding interest in protein engineering as well as veterans looking for new approaches to apply in established discovery programs.

Presently, intensive and global attention is being devoted to "biotechnology"--the technology utilizing marvelous capacities of living things for human welfare. Each country is strongly promo ting its development. In particular, enzyme engineering, whose pur pose is to utilize efficiently enzymes, microorganisms, and cultured plant as well as animal cells as organic catalysts, is one of the main themes in the field of biotechnology. Under these circumstances, the Sixth Enzyme Engineering Confe rence was held at Kashikojima, Mie Prefecture, Japan from September 20 to 25, 1981, under the joint auspices of the Engineering Foun dation of New York and the Japanese Society of Enzyme Engineering. This series of international conferences has been held biannually since 1971. The first three and the fifth conferences were held in the United States and the fourth one was in the Federal Republic of Germany. This sixth conference was the first to be held in Asia; and it was significant that a number of participantGBP could visit Japany, which has produced successful achievements in the field of biotechnology.

In September 1998 experts from 19 countries came together for an interdisciplinary discussion of the function of animal peroxidases, a family of enzymes embracing myeloperoxidase, eosinophil peroxidase, thyroid peroxidase and lactoperoxidase. Their papers have been updated for publication, yielding a wide-ranging overview of the state of the art. The chapters cover a wide range of topics, including three-dimensional structure of representative family members, their biosynthesis and intracellular transport, mechanism of action as well as applications to clinical medicine. They are of clinical relevance in, for example, arteriosclerosis, multiple sclerosis, infections, tumorigenesis, rheumatic diseases and hypothyroidism. This book forms an excellent introduction for anyone interested in the peroxidase family of enzymes.

In recent years, a number of groundbreaking structural and mechanistic studies deepened our understanding of helicase mechanisms and established new approaches for their analyses. Many fundamental mechanistic questions ranging from the mechanism of force generation, mechanochemical coupling to distinct mechanisms by which the same enzyme translocates on DNA removing obstacles, unwinds DNA and/or remodels nucleoprotein complexes, however, remain to be answered. It is even less understood how the helicase motors are incorporated into a wide range of genome maintenance and repair machines. The field has reached a stage when the studies of molecular mechanisms and basic biology of helicases can and shall be integrated with the studies of development, cancer and longevity. The objective of this book is to provide the first systematic overview of structure, function and regulation of DNA helicases and related molecular motors. By integrating the knowledge obtained through the diverse technical approaches ranging from single-molecule biophysics to cellular and molecular biological studies the editors aim to provide a unified view on how helicases function in the cell, are regulated in response to different cellular stresses and are integrated into large macromolecular assemblies to form a complex and adaptive living system.
