Enzyme and Microbial Biosensors: Techniques and Protocols (Methods in Biotechnology #6)

by Ashok Mulchandani and Kim R. Rogers

In 1962 Clark and Lyons pioneered the concept of a biosensor. They p- posed immobilizing enzymes at electrochemical detectors to form “enzyme el- trodes” in order to expand the analyte range of ther base sensor. Smce then, the field of blosensors has greatly expanded. Some of the reasons for the expansion include both advances in signal transduction technologies and the incorporation of different biological sensing elements (Table 1). As a consequence, there are now a bewildering array of permutations of the biological sensing element and signal transducers that can be used to c- struct a biosensor. The purpose of the two volumes of Protocols and Te- niques in Biosensors is to provide a basic reference tool and starting point for use by graduate students, postdoctoral and senior researchers, and technicians m academics, industry, and government research establishments, to enable rapid entry into the field of biosensors. There are a variety of approaches that researchers employ to select a combination of bioaffinity elements and signal transducers. One commonly used approach is to identtfy the compound or compounds of interest; identify the biological molecule that yields an appropriate recognitionlselectivtty and dynamic concentration range for the assay; and choose an assay format and signal transduction technology that will meet the analytical requirements for the proposed application, This volume, Enzyme and Microbial Biosensors: Techniques and Protocols, describes a variety of transduction technologies that have been interfaced to enzymes and microorganisms.

Enzyme- and Transporter-Based Drug-Drug Interactions: Progress and Future Challenges

by K. Sandy Pang A. David Rodrigues Raimund M. Peter

Germination of the thought of "Enzymatic- and Transporter-Based Drug-Drug Interactions: Progress and Future Challenges" Proceedings came about as part of the annual meeting of The American Association of Pharmaceutical Scientists (AAPS) that was held in San Diego in November of 2007. The attendance of workshop by more than 250 pharmaceutical scientists reflected the increased interest in the area of drug-drug interactions (DDIs), the greater focus of PhRMA, academia, and regulatory agencies, and the rapid pace of growth in knowledge. One of the aims of the workshop was to address the progress made in quantitatively predicting enzyme- and transporter-based DDIs as well as highlighted areas where such predictions are poor or areas that remain challenging for the future. Because of the serious clinical implications, initiatives have arisen from the FDA (http://www.fda.gov/cber/gdlns/interactstud.htm) to highlight the importance of enzyme- and transporter-based DDIs. During the past ten to fifteen years, we have come to realize that transporters, in addition to enzymes, play a vital role in drug elimination. Such insight has been possible because of the continued growth in PK-ADME (pharmacokinetics-absorption-distribution-metabolism-excretion) knowledge, fueled by further advances in molecular biology, greater availability of human tissues, and the development of additional and sophisticated model systems and sensitive assay methods for studying drug metabolism and transport in vitro and in vivo. This has sparked an in-depth probing into mechanisms surrounding DDIs, resulting from ligand-induced changes in nuclear receptors, as well as alterations in transporter and enzyme expression and function. Despite such advances, the in vitro and in vivo study of drug interactions and the integration of various data sets remain challenging. Therefore, it has become apparent that a proceeding that serves to encapsulate current strategies, approaches, methods and applications is necessary. As Editors, we have assembled a number of opinion leaders and asked them to contribute chapters surrounding these issues. Many of these are the original Workshop speakers whereas others had been selected specially to contribute on topics related to basic and applied information that had not been covered in other reference texts on DDI. The resulting tome, entitled Enzyme- and Transporter-Based Drug Interactions: Progress and Future Challenges, comprises of four sections. Twenty-eight chapters covering various topics and perspectives related to the subject of metabolic and transporter-based drug-drug interactions are presented.

Enzyme Biocatalysis: Principles and Applications

by Andrés Illanes

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.

Enzyme Cascade Design and Modelling

by Selin Kara Florian Rudroff

This book provides a comprehensive overview of the recent developments achieved in the field of chemo/enzymatic cascades with topics spanning from design (in vitro and in vivo) to kinetic- and process modelling as well as process control. Opportunities and challenges of building multi-step chemo/enzymatic reactions are discussed, whereby the latter are critically assessed in each chapter and methods to ease the implementation are explored. Both, multi-enzymatic cascades and chemo-enzymatic cascades are presented with the motivation of combining the strengths of these two worlds (e.g. selectivity, activity and robustness) not neglecting the obstacles and challenges of such endeavour. Furthermore, the use of non-conventional media for catalytic cascade reactions, recent achievements and potential for future developments in a technical environment are addressed.

The Enzyme Catalysis Process: Energetics, Mechanism and Dynamics (Nato Science Series A: Ser.)

by A. Cooper

This volume represents the proceedings of a NATO Advanced Studies Instituteheld near Barga (Italy), July 11-23, 1988, involving over 90 participants from more than twelve countries of Europe, North America and elsewhere. It was not our intention at this meeting to present a complete up-to-the-minute review of current research in enzyme catalysis but t·ather, in accord wi th the intended spiri t of NATO ASis, to gi ve an opportunity for advanced students and researchers in a wide variety of disciplines to meet tagether and study the problern from different points of view. Hence the lectures cover topics rauging from the purely theoretical aspects of chemical reaction kinetics in condensed matter through practical experimental approaches to enzyme structure, dynamics and mechanism, including the new experimental opportunities arising from genetic engineering techniques. Our approachwas unashamedly physical, both because the more biochemical aspects of enzymology are amply covered elsewhere and because progress in our understanding and application of the molecular basis of enzymic processes must ultimately come from advances in physical knowledge. We tried to cover as wide a spectrum as possible, and succeeded in gathering an expert and enthusiastic team of speakers, but there . are some inevitable omissions. In particular, and with hindsight, our discussions might have been enriched by more detailed coverage of general aspects of chemical catalysis - but readers requiring this background should find adequate references herein.

Enzyme Chemistry: Impact and applications

by Colin Suckling

As the first edition of this book was going through the publication process, a revolution was taking place in the technologies available for the study of enzymes. The techniques of molecular biology, especially in genetic engineering of organisms and in site specific mutagenesis of genes, were established and were being brought into use to solve many problems in in enzymology. Added to these fundamental and applied science, not least advances the possibility of generating catalysts from antibodies has become a topic of major interest. These major innovations have changed the emphasis of much bioorganic research; whereas in the past, the protein was often the 'sleeping partner' ina study, its detailed function is now the major focus of scientific interest. Similarly in industry, the potential of genetically manipulated organisms to satisfy the needs for the production of chemicals and foodstuffs has been widely recognised. The second edition of 'Enzyme Chemistry, Impact and Applications' takes on board these new develop­ ments whilst maintaining the overall aims and views of the first edition. Many of the chapters have been completely rewritten to take account of advances in the last five years especially with regard to the impact of biologically based technologies. Although the book continues to approach its subject matter from the point of view of the chemist, the increased interdisciplinary content of much modern science will be obvious from the discussion.

Enzyme Chemistry: Impact and applications

by Colin J. Suckling

In the molecular sciences, enzyme chemistry occupies a special niche as one of the major contact points between chemical and biological disciplines. The special properties of enzymes as selective and efficient catalysts are so central to current challenges to chemists that the development of enzyme chemistry in the past thirty years has been a major stimulus to chemical research in general. On the one hand studies of the intrinsic properties of enzymes and, on the other hand, their applications to synthesis, drug design, and biosynthesis have had an immense impact. This book brings together in one volume essays describing several such fields with emphasis on the applications. It would be unnecessarily repetitious to outline the approach and contents of the book in a Preface; the first short chapter is more eloquent than a formal Preface can be. I shall therefore encourage you to begin with the Introduction in Chapter 1 and here I wish to extend my warm thanks to those who have contributed to the production of this book: the authors for their acceptance of the overall concept of the book and for the thoughtfulness of their writing; Dr Charles Suckling, FRS and Professor Hamish Wood for their constructive criticism of the whole book; and Dr John Buckingham and his colleagues at Chapman and Hall for their efficiency and enthusiasm in transforming the typescripts into the book that you now hold.

Enzyme Engineering: Volume 4

by G. B. Broun

The unique catalytic properties of enzymes and the numerous techniques for immobilization of enzymes and cells continue to maintain a high degree of practical and scientific interest in this area called Enzyme Engineering. This fourth International Enzyme Engineering Confer­ ence was the first to be held outside of the United States. Europe was chosen as the site primarily to en­ able greater participation by investigators from that continent. The Engineering Foundation of New York, which was the principal sponsor of the first three conferences, was most fortunate in having the DECHEMA (Deutsche Gesell­ schaft fur chemisches Apparatewesen e. V.) of Frankfurt (Main), F. R. Germany as the cosponsor for this fourth conference. The success of the conference also was due in large part to the generous financial support, especially by the government of the Federal Republic of Germany, as well as by European enzyme and chemical companies. The fourth conference, held September 25-30, 1977 at Bad Neuenahr, Federal Republic of Germany was certainly successful, with 240 participants from 23 countries, repre­ senting many academic disciplines and occupational special­ ties. At this conference special emphasis was placed on the immobilization of whole cells and organelles, medical applications of immobilized enzymes and organelles, and the industrial status and future for immobilized biological materials.

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 participant£ could visit Japany, which has produced successful achievements in the field of biotechnology.

Enzyme Engineering: Volume 3

by E. Pye

The recent worldwide explosion of interest in enzymes as cata­ lysts in industrial processes has arisen primarily because of the potential of major innovative advances which have taken place over the last two decades, foremost among these being novel methods of enzyme immobilization and affinity chromatography for rapid enzyme purification. This interest is now being further stimulated by the remarkable commercial success of several enzyme-based industrial processes, particularly the production of high-fructose syrup in the U. S. and amino acid production in Japan. With the initiation of these and other processes, together with the readying for commercial­ ization of several other enzyme-based operations, interest has ex­ panded in other areas in which enzymes may playa useful role, particularly in medicine and analytical chemistry. The development of this technology has required the cooperative efforts of practi­ tioners of several disciplines, primarily chemical engineers, bio­ chemists and other life scientists. Indeed, from this cooperation is arising the new interdisciplinary field of Enzyme Engineering. To stimulate communication, information exchange and advance­ ment of knowledge in this new field on an international level the Engineering Foundation, through the efforts of Lemuel B. Wingard, Jr. , initiated in 1971 a series of international conferences on Enzyme Engineering to be held biannually. The first two conferences were held in Henniker, New Hampshire, in the summers of 1971 and 1973, respectively, while the third conference, from which these proceedings derived, was held in August 1975 in Portland, Oregon.
