This book was released on 2012-12-06 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest trees constitute one of the major resources of the world and their utilization, either for structural purposes or for the materials which they yield, dates back to antiquity. Over the centuries, the exploitation of this resource has become progressively more sophisticated, and, in many parts of the world has led to the development of highly complex forest-based industries. The research and development work which led to these industrial uses fostered the formation of numerous technical societies and associations, which, through their meetings and publi cations, have facilitated communication and the exchange of ideas. Over the years, there have been numerous symposia devoted to wood and the many facets of its properties and utilization. However, rarely has the emphasis in such symposia been placed upon the living tree and the changes which it undergoes in relation to its ultimate utilization. Hence the Phytochemical Society of North America arranged the symposium, "The Structure, Biosynthesis, and Degradation of Wood", held at the University of British Columbia in August, 1976. the contributions to which form the basis of the present volume.

Available in PDF, EPUB and Kindle. Book excerpt: FROM THE AUTHOR'S PREFACE This book . . . is focused on the structure and function relationships of the four major hydrolytic enzymes, cellulases, cellobiohydrolases, b-glucosidases, and xylanases as it relates to their mechanism of action. It should be of interest to biotechnologists and industrial researchers interested in manipulating these enzymes to their full potential as catalysts for various current and new applications. It begins with an overview of the nature of cellulose and heteroxylan, followed by a description of the enzymes involved in its hydrolysis, their general structure, characteristics, and classification. Chapter 3 discusses how these various enzymes are integrated and associated for the efficient solubilization of cellulose and heteroxylan. This includes a review of the literature concerning the cellulosomes and other cellulolytic complexes. The chapter on production and purification provides an overview of this subject matter. . . . These first four chapters thus set the stage for the more comprehensive discussion of the mechanism of action of each of the primary hydrolases which follows. . . . [T]he data pertaining to the catalytic mechanism of both the retaining and inverting forms of these enzymes since such studies were initiated on cellulases . . . in 1954 is reviewed in Chapter 5. The book concludes with an overview of the mode of action of the enzymes and a discussion, citing a few examples, of how the modern methods of molecular biology, enzymology, and X-ray crystallography are being used to manipulate selected enzymes for a variety of biotechnological and industrial purposes. The information in this new book will be of value to scientists and researchers working in the areas of biochemistry, botany, crop science, ecology, microbiology and mycology, in addition to those in the forestry and forest product industries.

Download or read book Structural Biology of Enzymes Involved in the Biosynthesis and Biodegradation of Lignin written by and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lignin, a heterogeneous aromatic polymer, is a major contributor to plant cell wall recalcitrance, which inhibits the access to cellulose and cell wall sugars which are of high industrial value. Although the lignin polymer is essential for plant growth, control of the plasticity of monolignol biosynthetic and the lignin polymerization has allowed for the engineering of plants with designer lignins. One such approach is the use of the newly isolated monolignol acyltransferases, feruloyl-CoA monolignol transferase (FMT) and p-coumaroyl-CoA monolignol transferase (PMT), to catalyze the synthesis of ester-linked monomer conjugates that, when introduced into the lignin polymer, can reduce the severity of pretreatments needed to liberate cell wall sugars. In an industrial setting, such as the production of cellulosic ethanol, these pretreatments separate the lignin from the cellulose and hemicelluloses that are rich in industrially valuable sugars. However, the value of the lignin streams is still largely underappreciated, and the growing field of lignin valorization is exploring the deconstruction, conversion, and applications of high-value aromatics from lignin. Although chemical treatment methods may be better suited to handle the heterogeneous and racemic nature of natural lignin, the study of microbial processes for lignin degradation will add value to the field. Of particular interest is the cleavage of [beta]-ether linkages, abundant in lignin, catalyzed by the glutathione-dependent [beta]-etherase enzymes LigE and LigF from Sphingobium sp. In this thesis, a structural biology approach is used to characterize the monolignol transferases FMT and PMT and the [beta]-etherases LigE and LigF. Homology models of FMT from Chinese angelica (Angelica sinensis) and both PMT and FMT from rice (Oryza sativa) confirm the expected BAHD superfamily fold expected for these enzymes, and Chapter 2 details the work aimed at crystallizing these enzymes. X-ray crystal structures of LigE and LigF, detailed in Chapter 3, show that, although the monomers maintain the glutathione-S-transferase fold of this family, drastic differences in the dimer interfaces contribute to the stereospecificity of the enzyme.
