The intriguing complexity, precision, and regulation of the wide range of biologi cal processes is determined by intricate mechanisms of molecular recognition. Their nature is under intense scrutiny. In addition to the well-appreciated interac tion of proteins either with amino acid or nucleotide sequences, the investigation of their interplay with carbohydrate elements of cellular glycoconjugates current ly exerts increasing attraction. In the group of carbohydrate-binding proteins, lec tins are distinguished from antibodies or ligand-affecting enzymes, according to the most recent definition. The thorough analysis of their structure and function is considered as a focus to collect a critical mass of information for delineating details of a further array of biochemical processes with pivotal physiological im pact. Following an already century-long history of scientific description, reflected by subjectively chosen highlights (see the Brief History of Lectin Research at page VI), the excitement in glycobiological research that prevails today can easily be ex plained by our growing awareness of the multifarious significance of a sugar-code system of biological information. This present notion unmistakably has an im pact on lines of research in diverse disciplines like cell and molecular biology, histochemistry, or clinical sciences. It also prompts inherent practical questions such as how to obtain lectins, or how to employ them as instruments in various assay systems with the best possible results. Thus, this book is devoted intentionally to cover the techniques in different research fields that deal with lectins.

Plants synthesize a wide variety of unique glycan structures which play essential roles during the life cycle of the plant. Being omnipresent throughout the plant kingdom, ranging from simple green algae to modern flowering plants, glycans contribute to many diverse processes. Glycans can function as structural components in the plant cell wall, assist in the folding of nascent proteins, act as signaling molecules in plant defense responses or (ER) stress pathways, or serve within the energy metabolism of a plant. In most cases, glycans are attached to other macromolecules to form so-called glycoconjugates (e.g. glycoproteins, proteoglycans and glycolipids), but they can also be present as free entities residing in the plant cell. Next to the broad, complex set of glycans, plants also evolved an elaborate collection of lectins or proteins with a lectin-like domain, which can recognize and bind to endogenous (plants-own) or exogenous (foreign) glycans. Though still poorly understood in plants, the dynamic interactions between lectins and carbohydrate structures are suggested to be involved in gene transcription, protein folding, protein transport, cell adhesion, signaling as well as defense responses. As such, a complex and largely undetermined glycan-interactome is established inside plant cells, between cells and their surrounding matrix, inside the extracellular matrix, and even between organisms. Studying the biological roles of plant glycans will enable to better understand plant development and physiology in order to fully exploit plants for food, feed and production of pharmaceutical proteins. In this Research Topic, we want to provide a platform for articles describing the latest research, perspectives and methodologies related to the fascinating world of plant glycobiology, with a focus on following subjects: 1. Identification and characterization of plant glycans, their biosynthetic and degradation enzymes 2. Characterization of plant lectins and glycoproteins 3. Plant glycans in the plant’s energy metabolism 4. Role of plant glycans in plant defense signaling 5. Use of plant lectins in pest control 6. Plant lectins as new tools in human medicine 7.

This volume provides a comprehensive understanding of the enigmatic identity of the glycome, a complex but important area of research that has been largely ignored due to its complexity. The authors thoroughly deal with almost all aspects of the glycome, i.e., elucidation of the glycan identity enigma and its role in regulation of the cellular process, and in disease etiology. The book bridges the knowledge gap in understanding the glycome, from being a cell signature to its applications in disease etiology. In addition, it details many of the major insights regarding the possible role of the glycome in various diseases as a therapeutic marker. The book systematically covers the major aspects of the glycome, including the significance of substituting the diverse monosaccharide units to glycoproteins, the role of glycans in disease pathologies, and the challenges and advances in glycobiology. The authors stress the significance and huge encoding power of carbohydrates as well as provide helpful insights in framing the bigger picture. The Glycome: Understanding the Diversity and Complexity of Glycobiology details state-of-the-art developments and emerging challenges of glycome biology, which are going to be key areas of future research, not only in the glycobiology field but also in pharmaceutics.

This book is the first to be dedicated to the bioinformatics of carbohydrates and glycoproteins. It provides an introduction to this emerging field of science both for the experimentalist working in glycobiology and glycomics, and also for the computer scientist looking for background information for the development of highly sophisticated algorithmic approaches. The book provides an overview of the state-of-the-art in the field, with reviews on databases, and the tools in use for analysis, interpretation, and prediction of the structures of complex carbohydrates, and demonstrates the value of bioinformatics for glycobiology. The availability of comprehensive databases and corresponding bioinformatics tools, to access and analyse the large amounts of experimental data relating to the structure of carbohydrates, will be a prerequisite for the success of the large-scale glycomics projects that aim to decipher new, so far unknown, biological functions of glycans. Efficient bioinformatics descriptions and tools can considerably enhance the efficiency of glycomics research, in terms of data quality, analysis and experimental costs. For a complete understanding of the molecular processes in which carbohydrates are involved, such as protein–carbohydrate interactions and the impact of glycosylation on protein function, knowledge of the 3D structure of the carbohydrate, the protein–carbohydrate complex, or the glycoprotein is often indispensable. This book provides a thorough introduction into methods used for conformational analysis of carbohydrates. Key features: Describes bioinformatic approaches to handle carbohydrate-active enzymes and glycosylation. Provides an overview on bioinformatics tools that facilitate analysis of carbohydrate structures. Gives introduction into molecular modelling of carbohydrate 3D structure and carbohydrates contained in the Protein Databank. Assumes only a basic knowledge of biology and bioinformatics.

This volume surveys the chemistry, biochemistry, biosynthesis, metabolism and pharmacological properties of lectins. Lectins, which are most commonly found in plants, are widespread natural products with striking biological activities. Their specific ability to recognise and bind to simple or complex saccharides facilitates their role as effective information protein molecules. As agents of cell-to-cell recognition, lectins promote symbiosis between plants and specific nitrogen-fixing soil bacteria. As natural defensive molecules, they can protect plants against predators such as bacteria, fungi and insects. As part of our diet, lectins are powerful exogenous growth factors in the small intestine and influence our health, the digestive function and the bacterial ecology of the alimentary tract. Lectins are also important research tools in preparative biochemistry and cell science.

The role of lectins and glycoconjugates in various cellular processes is receiving increasing interest. Since many cellular glycoconjugates are ligands for lectins, they are used as efficacious tools in biochemistry and cell research. "Lectins and Glycobiology" provides all relevant techniques to investigate the structure and function of lectins and their various reactions. Included are methods for the preparation ofsynthetic carbohydrate ligands, the determination of physico-chemical properties of lectin- oligosaccharide interactions, the isolation and chemical modi- fication of lectins, and assays to detect and quantitate lectins. Several chapters focus on the study of signal transduction and cellular responses induced by lectins as well as on cellular adhesion and cell recognition involving lectin-glycoprotein interaction. Further major topics are molecular biological techniques such as the use of recombinant or mutant lectin genes.
