Glyco-Engineering


Book Description

Conceived with the intention of providing an array of strategies and technologies currently in use for glyco-engineering distinct living organisms, this book contains a wide range of methods being developed to control the composition of carbohydrates and the properties of proteins through manipulations on the production host rather than in the protein itself. The first five sections deal with host-specific glyco-engineering and contain chapters that provide protocols for modifications of the glycosylation pathway in bacteria, yeast, insect, plants and mammalian cells, while the last two sections explore alternative approaches to host glyco-engineering and selected protocols for the analysis of the N-glycans and glyco-profiling by mass spectrometry. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols and tips on troubleshooting and avoiding known pitfalls. Authoritative and extensive, Glyco-Engineering: Methods and Protocols offers vast options to help researchers to choose the expression system and approach that best suits their intended protein research or applications.




Protein Glycosylation


Book Description

Protein Glycosylation provides clear, up-to-date, and integrated coverage of key topics in this field. Particular emphasis is placed on the biosynthetic pathways that result in a wide variety of identified protein-bound oligosaccharides. Protein Glycosylation begins with an overview of the chemical structures of mono- and oligosaccharides, to provide a scientific basis for the later chapters. The book includes discussions on the purification, function, and enzyme kinetics of selected glycosidases and glycotransferases, as well as a review of the roles of oligosaccharides in glycoprotein function and the in vivo role of glycoproteins themselves. Finally, the in vitro synthesis of glycoproteins is presented, together with future directions in glycobiology. Protein Glycosylation serves as an excellent text for upper-level undergraduate and graduate students as well as a reference for those scientists whose training is not in glycobiology but who are moving into this field.




The Role of Glycosylation in Health and Disease


Book Description

Glycobiology is an emerging field of studying glycans (sugars) and glycoconjugates that are essentially involved in almost all biological processes, from fine-tuning glycoprotein function to protein-protein interactions, signaling, immune response, host-pathogen interactions, etc. However, due to structural complexity of glycans and analytical challenges this exciting field was lagging behind other areas of biology. With technological advancements growing number of glycans’ functions are being discovered and the study of glycans is becoming a cutting-edge discipline in basic and clinical research. Despite recent developments in glycobiology field, many aspects of glycosylation process still remain unknown, both in a healthy human organism and in pathological states. Human glycome is dynamic and changes with physiological triggers, immune challenges and disease. Atypical glycosylation is consequently a subject of disease biomarker research, and a target for therapeutic interventions. On the other hand, properties of glycosylated biotherapeutics are predominantly determined by their glycans. The Role of Glycosylation in Health and Disease provides a comprehensive overview of types and functions of glycans in a healthy human organism as well as their role in pathophysiology of different diseases and efficiency of glycosylated biotherapeutics. Written by the experts in the field, this book aims to bring glycobiology field closer to students, researchers in life sciences and professionals in biopharmaceutical industry.




Chemical Biology of Glycoproteins


Book Description

Glycans play a vital role in modulating protein structure and function from involvement in protein folding, solubility and stability to regulation of tissue distribution, recognition specificity, and biological activity. They can act as both positive and negative regulators of protein function, providing an additional level of control with respect to genetic and environmental conditions. Due to the complexity of glycosylated protein forms, elucidating structural and functional information has been challenging task for researchers but recent development of chemical biology-based tools and techniques is bridging these knowledge gaps. This book provides a thorough review of the current state of glycoprotein chemical biology, describing the development and application of glycoprotein and glycan synthesis technologies for understanding and manipulating protein glycosylation.







Protein Glycosylation: Cellular, Biotechnological and Analytical Aspects


Book Description

Recombinant DNA technology has enabled the efficient production of large quantities of many biologically important glycoproteins by expression in heterologuous mammalian cell lines. In such quantities these glycoproteins can be used not only in basic research but also - after manufacturing by biotechnological means - for commercial purposes. A recent GBF workshop (Braunschweig, Germany, June 1990) was devoted to this highly significant field. In 39 contributions world-leading experts give a state-of-the-art description ranging from basic research reports to perspectives of practical applications. Pharmaceutical companies involved in the production of clinically important glycoproteins (such as immune-modulators, differentiation factors, hormones and receptors) will find this book indispensable. Researchers from industrial laboratories with an emphasis on biotechnology will also find the book invaluable for their daily work.




Diabetes and Protein Glycosylation


Book Description

In the years since the initial discovery that blood from diabetic patients contains increased amounts of a posttranslationally gluco sylated form of hemoglobin (hemoglobin Ale)' an impressive number of studies have clarified and expanded the use of glycohemoglobin levels to assess disease status. Many other structural proteins have been shown to undergo similar changes, including proteins from tissues most commonly affected in diabetes (e.g., lens, aorta, peripheral nerve, basement membrane). Thus, the nonenzymatic glycosylation of hemoglobin emerges as an invaluable model for the pathogenesis of certain chronic diabetes complications. In addition to reviewing a wealth of investigative possibilities in the area of these chronic complications-including eye, kidney, nerve, and vascular disease-Dr. Cohen indicates how enhanced nonenzymatic glycosylation in uncontrolled diabetes underscores the pressing need for maintenance of long-term euglycemia. Dr. Cohen is an endocrinologist and diabetes specialist whose research activities have largely focused on the chemistry and metabo lism of the basement membrane in diabetes. This superb monograph on nonenzymatic glycosylation clearly shows the major trends of her past and present research and clinical activities. This book is beautifully written and a pleasure to read. It provides great insight into the mechanisms of the pathogenesis of the oom- vii viii Foreword cations of diabetes and should be of immense value not only to basic and clinical investigators, but also to internists, diabetologists, and endocrinologists in clinical practice.




Fundamentals of Glycosylation


Book Description

The diverse phenomenon of post-translational modifications of biological macromolecules (proteins, lipids, and nucleic acids) includes phosphorylation, glycosylation, ubiquitination, nitrosylation, methylation, acetylation, lipidation, and proteolysis. The mechanism of protein glycosylation has an important role in the regulation of human health. This book identifies the fundamentals of glycosylation that help in understanding the concepts of protein glycosylation and its significance.




Transforming Glycoscience


Book Description

A new focus on glycoscience, a field that explores the structures and functions of sugars, promises great advances in areas as diverse as medicine, energy generation, and materials science, this report finds. Glycans-also known as carbohydrates, saccharides, or simply as sugars-play central roles in many biological processes and have properties useful in an array of applications. However, glycans have received little attention from the research community due to a lack of tools to probe their often complex structures and properties. Transforming Glycoscience: A Roadmap for the Future presents a roadmap for transforming glycoscience from a field dominated by specialists to a widely studied and integrated discipline, which could lead to a more complete understanding of glycans and help solve key challenges in diverse fields.
