Extensive up-to-date references and rigorous peer-review of each chapter make this volume definitive and bring it to the active frontiers of research.
The ADAM Family of Proteases provides the first comprehensive review of the roles of ADAMs and the related ADAMTS proteases in biology and disease. Although a few members of the ADAM (a disintegrin and metalloprotease) family have been known for some time, it is only in recent years through advances in genome sequencing that the large size of this family of zinc metalloproteases has become apparent. These proteins have multiple domains including a protease domain and a disintegrin domain. A branch of the family, called ADAMTS, also have thrombospondin-like motifs. The role of ADAMs and ADAMTS members in a diversity of biological processes is gradually coming to light. For example, some ADAMs have critical roles in the ectodomain shedding of membrane proteins including tumour necrosis factor-a, the cell signalling molecule Notch and the Alzheimer 's amyloid precursor protein. Other ADAM and ADAMTS family members have key roles to play in sperm function and fertility, collagen processing, development, cardiac hypertrophy and arthritis.

Lena Daumanns's thesis describes structural and functional studies of the enzyme Glycerophosphodiesterase (GpdQ) from Enterobacter aerogenes. It also examines the properties of small mimics of this enzyme and related binuclear metallohydrolases such as the metallo-ss-lactamases to enhance our understanding of hydrolytic cleavage of important substrates like phosphoesters and -lactams. Overall, this project has led to a better understanding of the metal ion binding and active site structural features of the enzyme GpdQ. Daumann describes how she successfully immobilized phosphoesterase and related biomimetics on solid supports for potential applications in the area of bioremediation of organophosphate pesticides. Analysis shows that both the enzyme and biomimetics can be stored on the solid support without loss of activity. Furthermore, the author specroscopically and mechanistically characterized a number of Zn(II), Cd(II) and Co(II) complexes, some of which are among the most active biomimetics towards organophosphates reported to date. This thesis makes excellent reading for non-specialists because each chapter includes a short introduction section.

Designing artificial systems with catalytic efficiencies to rival those of natural enzymes is one of the great challenges facing science today. Our current level of understanding fails the basic, practical test - designing and making artificial systems with catalytic efficiencies to rival those of natural enzymes. Chemists and bio-scientists are well aware of this problem, and "artificial enzymes" have been a "hot topic" for many years. However, until now, there has been no book devoted specifically to this subject. This is the first book to provide a critical introduction to, and overview of, this exciting area. It is aimed at students and more senior researchers with specialist or general interests in the field. The book starts with a systematic overview of the most important properties of natural enzymes, with special emphasis on mechanisms and efficiency of catalysis. This is followed by a summary of the mechanisms involved in the major classes of reaction they catalyze, and spells out the logical progression from simple mechanistic models for particular reactions to the first, rudimentary artificial enzymes catalyzing them. Catalytic efficiency is the key criterion for inclusion. An analysis of the strengths and limitations of the classical design-based approach to catalysis by enzyme mimics leads on to a discussion of recent advances which use selection methods coupled with iterative techniques for creating and improving catalysts by natural methods. The comparison of natural and artificial catalysts requires a quantitative understanding based on the interpretation of kinetic measurements. Key skills in data interpretation are introduced in a guided approach that connects the formal treatment of kinetic measurements with their chemical and biological interpretation.
In an intriguing series of experiments carried out many years ago, a common scientific belief, feted by no less than three Nobel prizes, was brought into question. The observations were about proteins-the molecules that the genetic code specifies and that are in one way or another central to all of life's activities. The experiments however were not about what proteins do, but how they are moved, in particular how they are moved from where they are made to where they act. The results of these studies conflicted with the standard view of how this happens, and thus became controversial. The standard view, the vesicle theory of protein secretion, envisions proteins being carried within and out of cells en masse in membrane-bound sacs or vesicles. The controversial experiments demonstrated that to the contrary individual protein molecules cross the relevant membranes as a result of their own motion. This was thought to be impossible at the time. Proteins Crossing Membranes is a personal narrative that tells the story of the controversy. Among other things, the author illustrates that scientists, like the rest of us, can rigidly hold onto their beliefs despite evidence that they are misguided. Key Features Reviews the data in support and critical of the vesicle theory of protein secretion Explores the ways scientists respond to evidence that challenges a favored theory Documents the author's personal experiences in this conflict-laden situation
Enzyme Kinetics and Mechanisms takes the reader through the experimental techniques and the logic by which the mechanisms of enzyme-catalyzed reactions can be elucidated by the results of steady-state kinetics and related experiments. It is meant to make these investigations both satisfying and effective. In distinction to other available descriptions, the descriptions in enzyme Kinetics and Mechanisms are limited to more commonly utilized and useful models and techniques. The logic relating the chemical models to the mathematical models and the logic of relating the mathematical models to data is presented in rather concise text, figures and equations. The development of mathematical models from chemical models is done by a unique algorithm that is both simple and quick, and the same concept are utilized to develop models for the effects of a variety of reaction conditions on the initial velocity. In addition, the various relationships of data, mathematical models and the chemical models is illustrated with examples from the scientific literature. Enzyme Kinetics and Mechanisms is intended for research workers, graduate students, post doctoral associates, and faculty in biochemistry and molecular biology who are interested in the techniques and logic by which mechanisms of enzymes-catalyzed reactions can be elucidated by investigation of steady-state kinetic experiments.

This volume highlights recent progress on the fundamental chemistry and mechanistic understanding of metallocofactors, with an emphasis on the major development in these areas from the perspective of bioinorganic chemistry. Metallocofactors are essential for all forms of life and include a variety of metals, such as iron, molybdenum, vanadium, and nickel. Structurally fascinating metallocofactors featuring these metals are present in many bacteria and mediate remarkable metabolic redox chemistry with small molecule substrates, including N2, CO, H2, and CO2. Current interest in understanding how these metallocofactors function at the atomic level is enormous, especially in the context of sustainably feeding and fueling our planet; if we can understand how these cofactors work, then there is the possibility to design synthetic catalysts that function similarly.
Enzyme immobilization on solid supports has been considered for a long time as an attractive solution to perform sophisticated organic synthesis, which is required in the preparation of fine pharmaceutical chemicals. But in the late 1990s, the tremendous progress in molecular biology fundamentals opened up the possibility of feeding a toolbox for building new bioinspired nanotechnologies. Among them is the goal of repositioning biocatalysts in environments mimicking their genuine working place-the cell. The research presented in this book was selected among the most impressive achievements in the fields of enzyme bioconjugation and bioinspired nanosupports. It opens up potential applications in nanocatalysis and for lab-on-a-chip and biosensor devices, drug delivery vectors, and nanometrology. Most of the supports described pertain to soft materials (cells, virus, polymers, DNA) and most of the examples benefit from the amazing properties of proteins and DNA to self-assemble, according to the "bottom-up law," a specific feature of all living systems. The enzyme nanocarriers also have the potential to be grafted on solid supports through "top-down" technologies, spanning orders of magnitude from the nano- to the mesoscale and above. The book is a rich source of inspiration for researchers seeking to build smart materials requiring nanoscale positional control of functional proteins on various carriers. |
