Carbohydrate Biotechnology Protocols


Book Description

We are in a phase of the evolution of biotechnology in which the true and potential commercial importance of carbohydrates is becoming appre- ated more fully. Progress in providing hard facts to establish the commercial value ofpolysaccharides and oligosaccharides is limited, as always, by lack of funding and by a relative shortage of skilled practitioners in the production and analysis of those materials. Carbohydrate science has a reputation, not unmerited, for technical difficulty owing to the structural similarity of the many monosaccharide monomers and the potential, and real, complexity of oligosaccharides and polysaccharides, particularly heterosaccharides conta- ing many different monomers. Modem analytical and synthetic methods, in many cases using enzyme technology, are beginning to allow this complexity to be unraveled. Carbohydrate Biotechnology Protocols is aimed at those newcomers who have an interest in the production and use of carbohydrate materials, but have shied away from involvement for lack of detailed descriptions of appropriate methods, including the type of practical hints that may be provided by those skilled in those methods, but that are rarely described in research papers. The majority of the contributions to this book conform to the established format of the Methods in Biotechnology series. They begin with the theoretical and c- mercial background to the method or group of methods, provide a list of the reagents and equipment required for the procedure, then give a detailed st- by-step description of how to carry out the protocol.




Enzymes in Carbohydrate Synthesis


Book Description

Not only assessing the past, present, and future uses of enzymes to synthesize carbohydrates, this volume also illustrates the significance of carbohydrate chemistry and describes how the combination and use of modern enzyme chemistry can advance exploration in the field. Details research at the interface of chemistry and biology for carbohydrate chemistry by demonstrating how to integrate chemical reactions and biological techniques that can be used to synthesize complex bioactive monosaccharides, oligosaccarides, and glycoconjugates. Of particular interest are chapters by George Whitesides and Chi-Huey Wong covering the use of enzymes in monosaccharide synthesis, and Hindsgaul, Thiem, Nilsson, and Whitesides describing the use of activated sugar nucleosides and glycosyltransferases in the synthesis of oligosaccharides and polysaccharides.

Novel enzymes for functional carbohydrates production


Book Description

This book focuses on the latest research and new techniques in the field of functional carbohydrate-related enzymes. Carbohydrates are a key form of energy for most organisms. The “good” carbohydrates generally refer to functional carbohydrates. In addition to the low or moderate energy-supplying function, they have more nutritious value than traditional carbohydrates and some of them also have health-promoting effects especially prebiotic actions. Several enzymatic methods for the synthesis of such carbohydrates have been discovered and developed in the recent decades, providing a new range of application areas for these novel enzymes. This book addresses the classification of functional carbohydrate-related enzymes and the overall development in food enzyme in Chapter 1. Chapters 2-5 describe the isomerases or epimerases involved in the production of rare sugars, such as D-allulose, D-mannose, D-tagatose, and D-allose. While the studies of the enzymes related to fructo-oligosaccharides (FOS) and galacto-oligosaccharides (GOS) dominate the scientific literature in the field of enzymatic production of health-functional oligosaccharides, some enzymes also show promise for the emerging oligosaccharide production, which are introduced in Chapters 6-8. Chapters 9-12 summarize the new enzymatic technologies and applications in fructan- and glycan-related industries. The last Chapter gives an overall prospective on the trends of enzymatic functional carbohydrate production. This book is a valuable resource for researchers and graduate students in the fields of biotechnology, enzyme engineering, and carbohydrate production, as well as the health industry.

Carbohydrate Bioengineering


Book Description

The Carbohydrate Bioengineering Meeting held in Elsinore, Denmark, April 23-26, 1995, gathered 230 scientists, mostly from Europe, with interest in carbohydrate analysis and structure; carbohydrates in medicine and glycopathology; structure, function, application, and protein engineering of carbohydrate active enzymes; oligo- and polysaccharides of industrial interest; and production of carbohydrate containing new materials. The first chapters address glycoconjugates as modulatory and recognition molecules, structure determination using NMR and mass spectrometry, and microdialysis-chip enzyme-based sensors. Active site mutations coupled with crystal structures and synthetic substrate analogue interactions as well as new three-dimensional structures and binding domains for biotechnological applications are included in the chapters. Carbohydrate active enzymes turned out to be a predominant topic. The rapid development in glycobiology and glycotechnology has resulted in an enormous increase in our knowledge on the structure conversion, and application of carbohydrates in industry and medicine.
