Part I covers modern advances in the determination of glycoprotein structure and in the biosynthesis of mammalian, bacterial, yeast, plant and insect glycoproteins. There are also two chapters on functional aspects (glycoprotein hormones and collagens). The content of the volume is very comprehensive in that, most contributors have focussed on discussing, in depth, the wealth of most recent advances in their field, and referring to previous reviews of older work for background information. This method can effectively produce a very wide subject coverage in a smaller number of chapters/volumes. The volume is an important information source for all glycobiologist researchers (senior investigators, post-doctoral fellows and graduate students), and as a good, comprehensive, reference text for scientists working in the life sciences.

Although glycoproteins and proteoglycans have been a subject of re search for many years, it is only during the last five or so years that they have aroused the interest of a very broad cross section of investigators in the biological sciences. The reason for this expanded interest in these molecules is simple: not only are glycoproteins and proteoglycans ubiq uitous, but many are molecules with well-defined and important biological functions. The list of molecules that fall into this category grows daily; interferon, immunoglobulins, certain hormones, many cell surface recep tors, and viral coat proteins are but a few examples. Thus, investigators with interests as diverse as viral replication. cell-cell interactions. poly isoprenoid synthesis, secretory processes, hormone responses, embryonic development, and immunology have become concerned with glycopro teins and proteoglycans. The objective of this book is to summarize the current state of knowledge on the biochemistry of these molecules. Coverage is by no means encyclopedic; rather the thrust is to emphasize the recent ad vances. The first chapter deals primarily with structural work on the oligosaccharide chains of glycoproteins, but it will be apparent in it and in the succeeding two chapters on biosynthesis that not only do structural studies aid biosynthetic investigations, but that studies on biosynthesis often playa major role in elucidation of structure.

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.

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.

This volume presents methods used for the analysis of glycoproteins at different levels—intact, subunit, glycopeptide, and monosaccharide--, and discusses and solves most analytical challenges that a scientist working on glycoproteins may come across. The chapters in this book cover topics such as the role of glycosylation on the properties of therapeutic glycoproteins; different analytical methods to characterize glycosylation, from the intact proteins to the glycan level, for both N-linked and O-linked glycoproteins; mass spectrometry imaging methodology for glycosylation analysis in tissues; approaches to characterizing glycosylation on cultured cells; and the use of cloud computing to deploy mass spectrometry data analysis. Written in the highly successful Methods in Molecular Biology series format, 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. Cutting-edge and thorough, Mass Spectrometry of Glycoproteins: Methods and Protocols is a valuable resource for scientists interested in learning more about this developing field.

This book is in many ways a sequel to The Biochemistry ojGlycoproteins and Proteoglycans. The enormous recent progress in understanding the biological roles of glycoproteins has prompted the present volume. The reasons for studying glycoproteins have multiplied, and in the present volume the roles played by glycoproteins are explored in a variety of biological situations. The first two chapters describe molecules involved in cell-substratum and cell-cell interactions in a broad sense, and also focus on recent progress in identifying specific attachment molecules. Our understanding of how normal processes, such as cellular differentiation and tissue organization, are regulated is dependent on understanding how cells interact with the extracellular matrix. When these processes go awry the consequences can be tragic, for example, when manifest as birth de fects and cancer. Our ability to devise appropriate therapies is in many cases limited by our understanding of such cell-matrix interactions. The third chapter explores the roles by glycoproteins during early mammalian development. The carbohydrate portions c1early play very important roles in presenting information during early embryogenesis, and an unusual tumor stern cell, the embryonal carcinoma, looks very promising in pro viding an experimental system for understanding how the expression of these complex carbohydrate determinants is regulated. The next three chapters explore the biology of glycoproteins in distinct situations: in the immune system, in the nervous system, and during erythropoiesis.

In the last 50 years molecular biology was dominated by the exploration of proteins and nucleic acids. Beside their role in energy metabolism, oligos- charides,which represent thethirdclass ofbiomacromolecules, have received less attention. Today it is well established that oligosaccharides are involved in many important biologicalregulation and recognition processes fromp- tein folding to cell-cell communication. Glycosylation of proteins is the most complexformofco-andposttranslationalmodi'cation. Thedeterminationof structure-function relationships, however, remains dif'cult due to the mic- heterogeneity of glycoproteins that exist in many different glycoforms. Thus chemical synthesis of glycoproteins and glycopeptides with de'ned glycan structures plays a pivotal role for the detailed determination of the role of protein glycosylation. This topic is covered by the ?rst two chapters of this bookdealingwiththechemicaland enzymatic synthesis ofglycopeptides and glycoproteins. The third chapter describes the construction of glycopeptide andglycoproteinmimetics containingnon-naturalstructuralelements. These so-calledneoglycopeptidesandneoglycoproteins,respectively,canprovide- sight on the importance of distinct structural elements on biological activity andmayhaveimproved propertiessuchasanincreased stability.

Glycopeptide antibiotics are glycosylated secondary metabolites of bacteria and fungi that are synthesized by non-ribosomal peptide synthetases. Some of them serve as antibiotics of last resort in the treatment of nosocomial infections with enterococci and methicillin-resistant Staphylococcus aureus (MRSA) strains. Their structure, biosynthesis, and mode of action are summarized in the ?fth chapter. The last chapter covers current methods for the determination of high-resolution structures of glycopeptides and glycoproteins mainly based onNMRspectroscopy, X-raycrystallography,and molecular modeling.
