This book introduces readers to industrially important enzymes and discusses in detail their structures and functions, as well as their manifold applications. Due to their selective biocatalytic capabilities, enzymes are used in a broad range of industries and processes. The book highlights selected enzymes and their applications in agriculture, food processing and discoloration, as well as their role in biomedicine. In turn, it discusses biochemical engineering strategies such as enzyme immobilization, metabolic engineering, and cross-linkage of enzyme aggregates, and critically weighs their pros and cons. Offering a wealth of information, and stimulating further research by presenting new concepts on enzymatic catalytic functions in basic and applied contexts, the book represents a valuable asset for researchers from academia and industry who are engaged in biochemical engineering, microbiology and biotechnology.

This book was written with the purpose of providing a sound basis for the design of enzymatic reactions based on kinetic principles, but also to give an updated vision of the potentials and limitations of biocatalysis, especially with respect to recent app- cations in processes of organic synthesis. The ?rst ?ve chapters are structured in the form of a textbook, going from the basic principles of enzyme structure and fu- tion to reactor design for homogeneous systems with soluble enzymes and hete- geneous systems with immobilized enzymes. The last chapter of the book is divided into six sections that represent illustrative case studies of biocatalytic processes of industrial relevance or potential, written by experts in the respective ?elds. We sincerely hope that this book will represent an element in the toolbox of gr- uate students in applied biology and chemical and biochemical engineering and also of undergraduate students with formal training in organic chemistry, biochemistry, thermodynamics and chemical reaction kinetics. Beyond that, the book pretends also to illustrate the potential of biocatalytic processes with case studies in the ?eld of organic synthesis, which we hope will be of interest for the academia and prof- sionals involved in R&D&I. If some of our young readers are encouraged to engage or persevere in their work in biocatalysis this will certainly be our more precious reward.

In this thesis, Xiaoshi Wang investigates the function and mechanism of a newly discovered heme-thiolate peroxygenase, AaeAPO. This enzyme class comes from Agrocybe aegerita and is used in the conversion of inert hydrocarbons to alcohols. Xiaoshi's work focuses on an extracellular P450 enzyme which is not limited in its stability and lack of solubility and therefore is relevant for widespread industrial use. The author demonstrates that the peroxygenase catalyzes a wide range of reactions. In some cases the author even describes very difficult transformations in molecules that are highly inert. Her detailed investigations provide a mechanistic framework for how the peroxygenase catalyzes such a large number of reactions. A major highlight of this thesis is the identification of key short-lived intermediates in the catalytic cycle of the peroxygenase, using rapid kinetic and spectroscopic methods, as well as the elucidation of the thermodynamic properties of these high-energy intermediates. This work adds new insight into an important class of enzymes.

This book is the proceedings of the 7th International Summer School on Biophysics: Supramolecular Structure and Function, held September 14-26, 2000, in Rovinj, Croatia. An enormous amount of new knowledge on the molecular basis of biological phenomena has emerged in the rapidly expanding field of biophysics. The principles and methods of modern biophysics now provide a strong foundation for all of the biosciences, and serve as a rational common language for scientists from various disciplines. The series of books on Supramolecular Structure and Function was inspired by the International Summer School on Biophysics, established under the sponsorship of IUPAB, UNESCO, and ICGEB, held in Rovinj, in 2001, and follows the successful interdisciplinary approach. This volume covers some powerful methods, such as analytical centrifugation, mass spectrometry, fluorescence spectroscopy, infrared spectroscopy, electron spin resonance and nuclear magnetic resonance, for the study of complex biological structures, and discusses useful physical concepts as applied to biological and biochemical systems. Case-orientated studies concentrating on particular methodologies are presented and examples are given, addressing some of the most important aspects of structure-function relationship in biological assemblies. Biophysics nowadays collaborates closely with molecular biology and bioinformatics as well as with neurosciences, and this is also demonstrated in this book. The book should be of interest both to experienced researchers wishing to widen their insight into molecular structure and function, and to younger scientists at the doctoral and postdoctoral level interested in the molecular nature offundamental biological entities and phenomena.

This volume, as does Volume 176, provides a general background of modern NMR techniques, with a specific focus on NMR techniques that pertain to proteins and enzymology, and a "snapshot" of the current state-of-the-art in NMR experimental techniques. These books enable the reader to understand a given technique, to evaluate its strengths and limitations, to decide which is the best approach, and, finally, to design an experiment using the chosen technique to solve a problem.

Carbonic anhydrase (CA) is a seemingly ubiquitous enzyme of profound physiological importance, which plays essential roles in respiration, acid-base homeostasis, bone resorption, calcification, photosynthesis, several biosynthetic pathways and a variety of processes involving ion, gas and fluid transfer. This enzyme, which is present in at least three gene families (a, ss, ?), has found favour as a model for the study of evolution of gene families and for site-directed mutagenesis in structure/function relationships, for protein folding and for transgenic and gene target studies. Since the early use of CA inhibitors as diuretics and in treating congestive heart failure, the enzyme has been target of considerable clinical attention. Much of this is now focused on endeavours to produce a new generation of such drugs for the effective treatment of glaucoma and other potential applications. Recent data, suggesting links between CA and various disease processes, including cancer, have stimulated further...

When marketing managers and financial managers join forces within any business, the result can often be poor communication on financial criteria and goals. The risk of this situation occurring is inevitably present when those with different professional backgrounds and roles are working in accordance with their own norms. In his seminal 1956 paper on general systems theory, the economist Kenneth Boulding referred to the phenomenon of "specialised ears and generalised deafness", which can be seen to exist when marketing managers are financially illiterate or when financial managers lack the necessary insights to design, implement and operate accounting systems which are useful to marketing managers in carrying out their roles. It is increasingly difficult to attach credence to the idea of marketing managers who lack financial skills, or financial managers who fail to relate to the context in which marketing managers operate. Understanding the marketing/accounting interface is therefore important in generating emergent properties from the interaction of marketers and accountants whereby the whole is greater than the sum of the parts. The chapters in this volume seek to address this challenge. This book was originally published as a special issue of the Journal of Marketing Management.

This book brings together and updates the latest information on the diversity of yeasts, their molecular features and their applications in the welfare of mankind. Yeasts are eukaryotic microfungi widely found in natural environments, including those with extreme conditions such as low temperatures, low oxygen levels and low water availability. To date, approximately 2,000 of the estimated 30,000 to 45,000 species of yeast on Earth, belonging to around 200 genera have been described. Although there are a few that are opportunistic human and animal pathogens, the vast majority of yeasts are beneficial, playing an important role in the food chain and in the carbon, nitrogen and sulphur cycles. In addition, yeasts such as Saccharomyces cerevisiae, Hansenula polymorpha and Pichia pastoris are used in expressing foreign genes to produce proteins of pharmaceutical interest. A landmark in biotechnology was reached in 1996 with the completion of sequencing of the entire S. cerevisiae genome, and it has now become a central player in the development of an entirely new approach to biological research and synthetic biology. The sequencing of genomes of several yeasts including Schizosaccharomyces pombe, Candida albicans and Cryptococcus neofromans has also recently been completed.

The book highlights work from many different labs that taught us abnormal HDACs potentially contribute to the development or progression of many human diseases including immune dysfunctions, heart disease, cancer, memory impairment, aging, and metabolic disorders.

This thesis reports studies on the substrate specificity of crucial ketosynthase (KS) domains from trans-AT Polyketide Synthases (PKSs). Using a combination of electrospray ionisation-mass spectrometry (ESI-MS) and simple N-acetyl cysteamine (SNAC) substrate mimics, the specificity of a range of KS domains from the bacillaene and psymberin PKSs have been succsessfully studied with regard to the initial acylation step of KS-catalysis. In addition, the ability to alter the substrate tolerance of KS domains by simple point mutations in the active site has been demonstrated. A series of acyl-ACPs have been synthesised using a novel methodology and employed to probe the substrate specificity of both KS domains and the previously uncharcterised acyl hydrolase domain, PedC. KS-catalysed chain elongation reactions have also been conducted and monitored by ESI-MS/MS. All KS domains studied exhibited higher substrate specificity at the elongation step than in the preceeding acylation step. Furthermore, a mechanism of reversible acylation is proposed using the PsyA ACP1-KS1 di-domain. The findings in this thesis provide important insights into mechanisms of KS specificity and show that mutagenesis can be used to expand the repertoire of acceptable substrates for future PKS engineering.

This volume commemorates the 30th anniversary of the discovery in 1971 of the first DNA topoisomerases, i.e topoisomerase I in E. coli, then provisionally named omega' protein, by the pioneering work of Jim Wang at Harvard University, who has contributed an article to this volume: Reflections on an accidental discovery' of the enzyme. Many kinds of topoisomerase have since been found from type I through to type VI in a variety of organisms ranging from viruses to higher eukaryote mammals. The wide distribution of enzymes in various forms of life implies that the DNA topoisomerase is essential for life.

In the mid 80's type I and II enzymes were found to be the intracellular targets of a number of efficacious anticancer drugs such as doxorubicin, mitoxantrone, etoposide and camptothecin as a result of a continued efforts of many investigators, especially Leroy Liu and his collaborators at Johns Hopkins University. Readers will find a series of chapters written by researchers actively engaged in the expanding field of topoisomerase and their inhibitors. The series of chapters cover review articles on pharmacology and the molecular mechanism of topoisomerase I- and II-targeting anticancer drugs in mammals and in the yeast Saccharomyces cerevisiae, which has proved to be a superb model organism for studies of anticancer drugs. This volume compiles up-to-date information on the topoisomerase-targeting compounds in clinical and preclinical development as a useful and important reference book for students and researchers in the field of pharmacology, toxicology, oncology and molecular biology.

The aims of this volume are to highlight the tremendous pharmacological potential of protein kinase and protein phosphatase inhibitors, to provide a thorough overview of the most remarkable achievements in the field and to illustrate how beneficial these studies can be for the advancement of both basic knowledge on biological regulation and deregulation and for the clinical treatment of a wide spectrum of diseases. This goal is attained by contributions of leader investigators in the field, who address the issue from different angles.

The second international symposium on Pectins and Pectinases was organized by Wageningen University and Research Centre and held in Rotterdam, May 6-10, 2001. This successful meeting was attended by around 130 participants from more than 20 countries representing almost all of the groups and industries working woridwide on pectins and pectinases. Following the first meeting on this subject held in December 1995, the symposium defInitely forms a platform for researchers and industries working in the fIeld, all within their own discipline and expertise. The symposium demanded a written account and this book is the resuit of that. It contains aIl keynote lectures and other oral presentations and provides an update about the current research. SignifIcant progress has been made in the last 5 years. This book provides an up-to-date insight into the research on pectin and pectic enzymes involved in their biosynthesis, degradation, modifIcation or utilization. The progress in the elucidation of the chemical structure of pectin and mode of action and 3-D structure of the pectin degrading enzymes allows us to identify and influence the functionality of pectins and pectic enzymes, both in vitra after isolation as weIl in the plants themselves (in planta). Other contributions deal with new applications of both pectin and pectin-degrading enzymes, while more and more attention is paid to health and nutritional aspects ofpectins. The book provides a 'state of the art' account for both beginners and experienced researchers of almost all disciplines of pectin research.
