Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods in Carbohydrate Synthesis presents in one volume a sequence of chapters leading from classical methods through to today's newest state-of -the-art technology for oligosaccharide synthesis. It places particular emphasis on the most recent breakthroughs in the field, including emerging technologies for both oligosaccharide and glycoconjugate synthesis. Chapters describing the synthesis of increasingly important glycosidic linkage analogs, as well as the oligosaccharides containing derivatives and analogs of natural sugars are included. While chemical-synthetic methods constitute the major part of the book, completing the volume is a section on the rapidly expanding and important field of enzymatic synthesis, also covering combined chemical and enzymatic synthesis. Chapters are written by leading experts in the field. Wherever possible, methods of synthesis are provided in sufficient detail to allow the reader to implement the techniques described. More than 1700 references are provided in the 21 chapters comprising the book. This volume should provide a wealth of information to a large number of synthetic organic chemists, medicinal chemists, protein chemists, biochemists, glycobiologists and cell biologists, including students in these fields.

Download or read book Enzymes in Carbohydrate Synthesis written by Chun-Hung Lin and published by . This book was released on 1995 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the synthetic utility of enzymes as catalysts for carbohydrate synthesis was explored. Sialic acid aldolase was applied to make high-carbon monosaccharides. This study included the discovery that re face attack on the acceptor carbonyl was observed toward scL-sugar substrates, instead of si face attack toward scD-sugar substrates; i.e., the opposite stereoselectivity occurred with enantiomeric substrates. Examination of the product distribution during the course of enzymatic reactions revealed that the stereoselectivity is thermodynamically controlled. CTP: CMP-3-deoxy- scD-manno-octulosonate cytidylyltransferase (CMP-KDO synthetase) was prepared for the synthesis of cytidine 5'-monophospho-3- deoxy- scD-manno-octulosonic acid (CMP-KDO) and analogs. The nature product of the enzyme, CMP-KDO, is unstable. Of several KDO analogs tested as substrates for this enzyme, 5-fluoro-2-keto-3,5-dideoxyoctulosonic acid (5-FKDO) was found to be a good substrate. The synthesis and characterization of the product, CMP-5-FKDO, represents the first stable CMP-KDO analog prepared enzymatically to date. A mechanism was proposed to explain the instability of CMP-KDO. A sialyl Lewis x dimer was synthesized enzymatically in three steps from an N-linked oligosaccharide prepared from egg yolk. Treatment of delipidated hen egg yolk with the protease orientase and neuraminidase gave a dimeric N- acetyllactosamine-containing oligosaccharide linked to asparagine. Addition of sialic acid and fucose catalyzed by [alpha]-2,3-sialyltransferase and [alpha]-1,3-fucosyltransferase provided the dimeric sialyl Lewis x, an active inhibitor of E-selectin with IC50 of 0.75 mM. In the enzymatic sulfation of polyfunctional biomolecules, 3'-phosphoadenosine-5'-phospho sulfate (PAPS) is a key intermediate and cofactor. In order to accomplish the regioselective sulfation of oligosaccharides, ATP sulfurylase, APS kinase, and Nod factor sulfotransferase were cloned and overexpressed in Escherichia coli. The first two enzymes were used in the mmol-scale synthesis of PAPS with regeneration of ATP. Additionally, PAPS was further used in the enzymatic sulfation of N,N'-diacetylchitobiose catalyzed by a recombinant Nod factor sulfotransferase, which was coupled with regeneration of PAPS from 3'-phosphoadenosine-5'-phosphate (PAP).
Download or read book Handbook of Carbohydrate Modifying Biocatalysts written by Peter Grunwald and published by CRC Press. This book was released on 2016-11-25 with total page 1056 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an actual overview of the structure, function, and application of carbohydrate-modifying biocatalysts. Carbohydrates have been disregarded for a long time by the scientific community, mainly due to their complex structure. Meanwhile, the situation changed with increasing knowledge about the key role carbohydrates play in biological processes such as recognition, signal transduction, immune responses, and others. An outcome of research activities in glycoscience is the development of several new pharmaceuticals against serious diseases such as malaria, cancer, and various storage diseases. Furthermore, the employment of carbohydrate-modifying biocatalysts—enzymes as well as microorganisms—will contribute significantly to the development of environmentally friendly processes boosting a shift of the chemical industry from petroleum- to bio-based production of chemicals from renewable resources. The updated content of the second edition of this book has been extended by discussing the current state of the art of using recombinantly expressed carbohydrate-modifying biocatalysts and the synthesis of minicellulosomes in connection with consolidated bioprocessing of lignocellulosic material. Furthermore, a synthetic biology approach for using DAHP-dependent aldolases to catalyze asymmetric aldol reactions is presented.

Download or read book Biocatalysts for Industry written by Jonathan S. Dordick and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of enzymes or whole cells (fermentatively active or resting; microbial, plant, or animal) to carry out selective transformations of commercial importance is the central theme of industrial biocatalysis. Traditionally, biocatalysis has been in the domain of the life scientist or biochemical engineer. However, recent advances in this field have enabled biocatalytic processes to compete head on with, and in some cases out perform, conventional chemical processing. Chemo-biocatalytic systems are being developed thereby combining the most attractive features of bio catalysts, namely high specificity, with those of chemical catalysts, such as high reactivities and wide substrate specificities. Hence, synthetic chemists and chemical engineers are now beginning to use biocatalysts as highly selective reagents in chemical synthesis and processing. This book is about biocatalysts and their past, present, and potential applications in the food, pharmaceutical, and chemical industries. The con cept of the book did not emanate from a meeting. Rather, it is a compila tion of selected examples where biocatalysis either has already made a significant impact in the aforementioned industries, or has the potential to make a substantial contribution. I have been fortunate to have assembled contributions from world-class researchers in the field of biocatalysis. Their timely contributions are sincerely appreciated.
