This book describes the recent developments in enzymology in carbohydrate engineering based on modern sciences and technology, collected from recent symposia on agricultural biotechnology. It builds a bridge between basic knowledge and biotechnology in the field of carbohydrate chemistry and enzymology. The fundamental research and application of carbohydrate enzymes to agricultural biotechnology, concentrating on the structures and biochemical properties of various enzymes, and their production and application in plant and food is extensively described. This book will provide the reader with the most up-to-date information on development of enzymology in carbohydrate engineering.

Pectins are one of the classes of complex structural plant cell wall polysaccharides. They are localized in the middle lamella and primary cell wall of higher plants. Pectins have a long-standing use as gelling agents whereas their enzymatic degradation or modification plays an important role in the processing of agricultural crops and the manufacturing of foods and beverages. Progress in pectin and pectinase research has been most prominent in two areas over the past 5 years. The first one concerns the analysis and elucidation of the complex chemical structure of pectin and identification of novel enzymes involved in the degradation of these structures. The second area concerns the mode of action and the 3-dimensional structure of various pectin degrading enzymes as well as the cloning of a large number of genes encoding enzymes involved in pectin degradation and modification. This book covers the following topics. First the structural, physical and chemical properties of pectin are treated followed by information about its biosynthesis and about the biological effects of pectin and its degradation products in biological systems such as plant-pathogen interactions and human nutrition. Identification of novel enzymes, the mode of action of different pectinases and the 3-D structure of bacterial pectate lyases forms the second block. This is followed by the genetics and regulation of pectinase biosynthesis in saprophytic and phytopathogenic microbial systems as well as in plant systems. Finally, developments in pectin manufacturing and application of pectinases in traditional (food, beverage) and novel technologies are treated. This book is meant for those actively involved in fundamental and applied aspects of pectin and pectinase research but it is also of value for those interested in plant cell wall biosynthesis and architecture, phytopathology, food technology and human nutrition. This book not only reflects the present status of research in the field but it will turn out to be a very useful reference work as well.
Marine bioprospecting is a highly topical subject - in both applied and basic research - but, as yet, the marine ecosystem is a relatively unexplored source of natural bioactive substances with potential therapeutic activity. This book addresses the use of marine enzymes in biocatalysis through a series of chapters from leading scientists within academic and industrial fields. Biocatalytic processes can take advantage of the habitat-related properties of marine enzymes, such as salt tolerance, hyperthermostability, barophilicity, cold adaptivity, and so on, whilst also taking into consideration substrate specificity and affinity. These evolved properties are linked to the metabolic functions of the enzymes and to the ecological aspects of the natural source. New properties can also be discovered at the molecular level of catalysis, particularly concerning the stereochemical characteristics of products.

Marine enzymes for biocatalysis initially examines the nature and level of interest in marine biological diversity, and outlines the fundamentals of biocatalysis. It goes on to detail sources of marine enzymes, and to analyse examples from both chemical and stereochemical viewpoints of catalysis, including microbial enzymes and animal or plant sources. The book goes on to explore the future potential of marine bioprospecting in biocatalysis.Compiles studies from leading scientists in a direct and accessible format. Includes practical descriptions of results, adding further details not often covered in formal articlesTakes a molecular view which fully explains the enzymatic aspects of reactions, particularly regarding biocatalytic characteristics and descriptions of bioprocessesSelects examples of chemical and stereochemical aspects of enzymatic action with respect to known terrestrial counterparts
Recent advances in biochemistry and biotechnology have enabled significant progress in basic research on carbohydrate-active enzymes and advances in their effective application. The mechanism of catalytic reaction of carbohydrate-active enzymes is not fully understood, though, as they often show unusual substrate specificity and modes of action. This comprehensive collection summarises some of the most important research in the field of carbohydrate-active enzymes, focusing on the enzymatic reaction mechanism, structure-function relationship and role in the living organism

The book is based on papers presented in the 2008 Agricultural Biotechnology Symposium Carbohydrate-active enzymes: structure, function and applications held on September 26th-27th 2008 in Seoul National University, Korea. This symposium was organized by the Center for Agricultural Biomaterials, Seoul National University, Korea, which has organized symposia on agricultural biotechnology annually since 1990. Many important results on new types of carbohydrate-active enzymes and their applications have been reported at these meetings. Papers in Part one of this collection focus on structure-function relationships of carbohydrate-active enzymes. Papers in Part two discuss functions and applications of carbohydrate-active enzymes, such as enzymes for grain processing and glycosidases and their mutants as useful tools for glycoside synthesis.

With its distinguished editor and international team of contributors, Carbohydrate-active enzymes: structure, function and applications is an essential reference for research scientists, post-graduate students and those in the food industry with an interest in enzymes.Summarises some of the most important research in the field of carbohydrate-active enzymesCovers topics ranging from enzyme classification and structural elucidation to applications of enzymes in food processing and other industries
