Book Description :

Carbohydrate-active enzymes are responsible for both biosynthesis and the breakdown of carbohydrates and glycoconjugates. They are involved in many metabolic pathways; in the biosynthesis and degradation of various biomolecules, such as bacterial exopolysaccharides, starch, cellulose and lignin; and in the glycosylation of proteins and lipids. Carbohydrate-active enzymes are classified into glycoside hydrolases, glycosyltransferases, polysaccharide lyases, carbohydrate esterases, and enzymes with auxiliary activities (CAZy database, www.cazy.org). Glycosyltransferases synthesize a huge variety of complex carbohydrates with different degrees of polymerization, moieties and branching. On the other hand, complex carbohydrate breakdown is carried out by glycoside hydrolases, polysaccharide lyases and carbohydrate esterases. Their interesting reactions have attracted the attention of researchers across scientific fields, ranging from basic research to biotechnology. Interest in carbohydrate-active enzymes is due not only to their ability to build and degrade biopolymers—which is highly relevant in biotechnology—but also because they are involved in bacterial biofilm formation, and in glycosylation of proteins and lipids, with important health implications. This book gathers new research results and reviews to broaden our understanding of carbohydrate-active enzymes, their mutants and their reaction products at the molecular level.

Book Description :

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.

Book Description :

Several efforts have been made in developing strategies to supply the enzyme market, as well as in reducing its costs. It includes the selection of an appropriate enzyme source and the optimization of enzyme properties and secretion. Carbohydrate-Active Enzymes (CAZymes) are industrially relevant biocatalysts that are capable of degrading plant cell wall biomass. The most important secreted enzymes related to plant cell wall decomposition are cellulases, hemicellulases, and auxiliary enzymes. These enzymes have been applied in the hydrolysis of plant biomass for the production of second-generation (2G) ethanol and several other high added value products. One of the bottlenecks for 2G ethanol production is the cost of enzymes applied on plant biomass hydrolysis. The improvement of proteins production by fungi applying system biology and genetic engineering is an interesting and promising strategy to reduce the enzymes cost and make the 2G ethanol production viable. Fungi play an important role in plant biomass degradation and biotechnology by producing and secreting high yields of enzymes. In spite of the fact that filamentous fungi present several advantages compared to other microorganisms due to the high level of proteins production, heterologous protein production is far from optimal levels and still needs to be improved. Currently, heterologous production of certain proteins is generally considerably lower than the levels obtained to homologous production. Many strategies have been studied in order to improve heterologous production of proteins by filamentous fungi, including the deletion of genes that encode for proteases, the deletion of lectin-like ER-Golgi cargo receptors and the co-expression of specific chaperones. It has been shown that the main bottleneck in the production of heterologous proteins is not caused by the low expression of the target gene. An experimental evidence suggests that most target proteins produced in filamentous fungi are lost or stuck in the secretory pathway due to errors in processing, modification or misfolding that result in their elimination by endoplasmic reticulum (ER) quality control. Misfolded proteins alter homeostasis and proper ER functioning resulting in a state known as ER stress. ER stress activates a conserved signaling pathway called unfolded protein response (UPR) and ER-associated protein degradation (ERAD), which upregulates genes responsible for restoring protein folding homeostasis in the cell and degrades misfolded protein in the cytosol by the ubiquitin-proteasome system. The genetic manipulation of individual genes and changes in the genome seems not to be the best alternative to overcome the main bottlenecks in heterologous protein secretion. However, the understanding of complex interactions of important proteins and genes, as well as how they are regulated is more promising.

Book Description :

The oil crisis during the 1970s turned interest towards the utilization of renewable resources and towards lignocellulosics in particular. The 1970s were also the cradle period of biotechnology, and the years when biotechnical utilization of lignocellulosic waste from agriculture and forestry gained priori ty. This was a logical conclusion since one of nature's most important biologi cal reactions is the conversion of wood and other lignocellulosic materials to carbon dioxide, water and humic substances. However, while biotechnology in other areas like medicine and pharmacology concerned production of expen sive products on a small scale, biotechnical utilization and conversion of ligno cellulosics meant production of inexpensive products on a large scale. Biotechnical utilization of lignocellulosic materials is therefore a very difficult task, and the commercial utilization of this technology has not progressed as rapidly as one would have desired. One reason for this was the lack of basic knowledge of enzyme mechanisms involved in the degradation and conversion of wood, other lignocellulosics and their individual components. There are also risks associated with initiating a technical development before a stable platform of knowledge is available. Several of the projects started with en thusiasm have therefore suffered some loss of interest. Also contributing to this failing interest is the fact that the oil crisis at the time was not a real one. At present, nobody predicts a rapid exhaustion of the oil resources and fuel production from lignocellulosics is no longer a high priority.
