This book highlights current approaches and future trends in the use of mass spectrometry to characterize protein therapies. As one of the most frequently utilized analytical techniques in pharmaceutical research and development, mass spectrometry has been widely used in the characterization of protein therapeutics due to its analytical sensitivity, selectivity, and specificity. This book begins with an overview of mass spectrometry techniques as related to the analysis of protein therapeutics, structural identification strategies, quantitative approaches, followed by studies involving characterization of process related protein drug impurities/degradants, metabolites, higher order structures of protein therapeutics. Both general practitioners in pharmaceutical research and specialists in analytical sciences will benefit from this book that details step-by-step approaches and new strategies to solve challenging problems related to protein therapeutics research and development.

The use of the chemical modification of proteins has evolved over the past 80 years, benefiting from advances in analytical, physical, and organic chemistry. Over the past 30 years, the use of chemical reagents to modify proteins has been crucial in determining the function and structure of purified proteins. This groundbreaking work is part of the foundation of emerging disciplines of proteomics, chemical biology, structure biology, and chemical proteomics. Chemical Reagents for Protein Modification, Fourth Edition provides a comprehensive review of reagents used for the chemical modification of proteins, representing a major revision of the work presented in previous editions. The completely updated Fourth Edition is substantially larger and includes five new chapters: Alkylating Agents Acylating Agents Nitration and Nitrosylation Oxidation Modification of Proteins with Reducing Agents There is greatly increased coverage of the chemical modification of cysteine, which is critical for bioconjugate synthesis. The chapter on reduction also provides information necessary for bioconjugate synthesis as well as for the processing of inclusion bodies. The book places emphasis on conditions that affect the specificity of the chemical modification of proteins, such as solvent and temperature. The format has been markedly revised, presenting information based on the chemical nature of the modifying material and on the amino acid residue modified. This new version has increased significance to biopharmaceuticals. Much of the information is in tabular form, which enables the rapid location of cited material.

A NATO Advanced Research Workshop entitled New Methods for the Study of Molecular Aggregates was held at Tbe Lodge at Kananaskis Village, Alberta, Canada from 16 -20 June 1996. In fact the meeting was entirely concerned with the problem of analyzing biomolecular complexes, so the title of these proceedings has been altered to give a more precise description of the content. Tbe workshop was hosted by the time-of-flight group of the Department of Physics at the University of Manitoba, and was attended by 64 participants from around the world. '!\venty-one invited talks were given and 27 papers were presented as posters. Of the 48 contributions, 22 papers (12 orals, 10 posters) are included in these proceedings. Tbe subject of the conference was the investigation of noncovalent biomolecular complexes, with particular focus on the application of mass spectrometry to their characterization. '!\vo new ionization techniques introduced in the late 1980s, electrospray ionization (ES I) and matrix-assisted laser desorptionlionization (MALDI), resulted in a breakthrough in mass spectrometry, enabling its use in molecular weight and primary structure determination of biopolymers larger than 100 kDa. Recently it has been discovered that ESI mass spectrometry mayaiso be used to characterize complexes containing noncovalent interactions, thus opening new perspectives for supramolecular chemistry. ESI mass spectrometry has the advantage that the sampie is introduced from a homogenous solution which can be maintained at near physiological conditions of pR, concentration, and temperature.

This book reviews the long-standing debate over the relative merits of a high-protein versus a low-protein diet. When protein (or 'animal substance') was first discovered in vegetable foods it was hailed as the only true nutritional principle. Leibig, the leading German chemist of the mid-nineteenth century, believed that it provided the sole source of energy for muscular contraction. In contrast, health reformers argued that high intakes were over-stimulating, leading to dissipation and decline. The subject came to widespread public attention again in the 1950s as the United Nations debated the need for providing protein supplements to Third World infants. At a time when the concern has resurfaced that over-consumption of protein in affluent societies may damage health, this book provides a fascinating historical perspective.

First published in 1943, Vitamins and Hormones is the longest-running serial published by Academic Press. The Series provides up-to-date information on vitamin and hormone research spanning data from molecular biology to the clinic. A volume can focus on a single molecule or on a disease that is related to vitamins or hormones. A hormone is interpreted broadly so that related substances, such as transmitters, cytokines, growth factors and others can be reviewed. This volume focuses on nociceptin opioid.

Na+-K+ ATPase or Na-pump ATPase, a member of "P"-type ATPase superfamily, is characterized by association of multiple isoforms mainly of it's - and - subunits. At present four different - ( -1, -2, -3 and -4) and three - ( -1, -2, and -3) isoforms have been identified in mammalian cells and their differential expressions are tissue specific. Regulation of Na+-K+ ATPase activity is an important but a complex process, which involves short-term and long-term mechanisms. Short-term regulation of Na+-K+ ATPase is either mediated by changes in intracellular Na+ concentrations that directly affect the Na+-pump activity or by phosphorylation/dephosphorylation-mediated by some stimulants leading to changes in its expression and transport properties. On the other hand, long-term regulation of Na+-K+ ATPase is mediated by hormones, such as mineralocorticoids and thyroid hormones, which cause changes in the transcription of genes of - and - subunits leading to an increased expression in the level of Na+-pump. Several studies have revealed a relatively new type of regulation that involves the association of small, single span membrane proteins with this enzyme. These proteins belong to the FXYD family, the members of which share a common signature sequence encompassing the transmembra ne domain adjacent to the isoform(s) of - subunits of Na+-K+ ATPase. Considering the extraordinary importance of Na+-K+ ATPase in cellular function, several internationally established investigators have contributed their articles in the monograph entitled "Regulation of Membrane Na+-K+ ATPase" for inspiring young scientists and graduate students to enrich their knowledge on the enzyme, and we are sure that this book will soon be considered as a comprehensive scientific literature in the area of Na+-K+ ATPase regulation in health and disease.

Daniel C. Liebler masterfully introduces the science of proteomics by spelling out the basics of how one analyzes proteins and proteomes, and just how these approaches are then employed to investigate their roles in living systems. He explains the key concepts of proteomics, how the analytical instrumentation works, what data mining and other software tools do, and how these tools can be integrated to study proteomes. Also discussed are how protein and peptide separation techniques are applied in proteomics, how mass spectrometry is used to identify proteins, and how data analysis software enables protein identification and the mapping of modifications. In addition, there are proteomic approaches for analyzing differential protein expression, characterizing proteomic diversity, and dissecting protein-protein interactions and networks.

New insights into the evolution and nature of proteins

Exploring several distinct approaches, this book describes the methods for comparing protein sequences and protein structures in order to identify homologous relationships and classify proteins and protein domains into evolutionary families. Readers will discover the common features as well as the key philosophical differences underlying the major protein classification systems, including Pfam, Panther, SCOP, and CATH. Moreover, they'll discover how these systems can be used to understand the evolution of protein families as well as understand and predict the degree to which structural and functional information are shared between relatives in a protein family.

Edited and authored by leading international experts, "Protein Families "offers new insights into protein families that are important to medical research as well as protein families that help us understand biological systems and key biological processes such as cell signaling and the immune response. The book is divided into three sections: Section I: Concepts Underlying Protein Family Classification reviews the major strategies for identifying homologous proteins and classifying them into families.Section II: In-Depth Reviews of Protein Families focuses on some fascinating super protein families for which we have substantial amounts of sequence, structural and functional data, making it possible to trace the emergence of functionally diverse relatives.Section III: Review of Protein Families in Important Biological Systems examines protein families associated with a particular biological theme, such as the cytoskeleton.

All chapters are extensively illustrated, including depictions of evolutionary relationships. References at the end of each chapter guide readers to original research papers and reviews in the field.

Covering protein family classification systems alongside detailed descriptions of select protein families, this book offers biochemists, molecular biologists, protein scientists, structural biologists, and bioinformaticians new insight into the evolution and nature of proteins.

A Unified Microscopic Approach to Analyzing Complex Processes in Molecular Motors Motor Proteins and Molecular Motors explores the mechanisms of cellular functioning associated with several specific enzymatic molecules called motor proteins. Motor proteins, also known as molecular motors, play important roles in living systems by supporting cellular transport and force generation via the transformation of chemical energy into mechanical work. The book presents established results, theoretical methods, and experimental observations related to biological molecular motors. It uses fundamental physical-chemical concepts and methods to develop a systematic theoretical framework for understanding motor protein dynamics. The author introduces the main ideas using simple arguments that avoid heavy mathematical derivations in favor of more intuitive physical understanding. Although the book assumes some rudimentary knowledge of cell biology, calculus, and basic ideas from chemistry and physics, it gives explanations and derivations for most results. Accessible to students and researchers in a wide range of scientific fields, this book provides a unified molecular picture for analyzing motor proteins. It connects major experimental facts on molecular motors to principal theoretical concepts consistent with the fundamental laws of chemistry and physics.

This book is concerned with applications of spectroscopic methods to determine protein structure in solution.

This new edited volume in the Springer Subcellular Biochemistry Series presents a comprehensive, state-of-the-art overview of the proteomics of peroxisomes derived from mammalian, Drosophila, fungal, and plant origin, and contains contributions from leading experts in the field. The development of sensitive proteomics and mass spectrometry technologies, combined with bioinformatics approaches now allow the identification of low-abundance and transient peroxisomal proteins and permits to identify the complete proteome of peroxisomes, with the consequent increase of our knowledge of the metabolic and regulatory networks of these important cellular organelles. The book lines-up with these developments and is organized in four sections including: (i) mass spectrometry-based organelle proteomics; (ii) prediction of peroxisomal proteomes; (iii) analysis of peroxisome proteome interaction networks; and (iv) peroxisomes in relation to other subcellular compartments. The editor Luis A. del Rio is Professor ad honorem of the Spanish National Research Council (CSIC) in the Group of Antioxidants, Free Radicals and Nitric Oxide in Biotechnology, Food and Agriculture, Department of Biochemistry and Cell & Molecular Biology of Plants, at the Estacion Experimental del Zaidin, Granada, Spain. Del Rio's research group focuses on the metabolism of reactive oxygen species (ROS), reactive nitrogen species (RNS) and antioxidants in plant peroxisomes, and the ROS- and RNS-dependent role of peroxisomes in plant cell signalling. The editor Michael Schrader is Professor of Cell Biology & Cytopathology in the Department of Biosciences at the University of Exeter, UK. Using mammalian peroxisomes as model organelles, Prof. Schrader and his team aim to unravel the molecular machinery and signalling pathways that mediate and regulate the formation, dynamics and abundance of these medically relevant cellular compartments.

Lectins have in the past been regarded by many scientists as curious proteins of uncertain structure and specificity that bind to carbohydrates of dubious significance themselves. All this is rapidly changing. The functional importance of glycosylation in cell-cell and cell-pathogen interactions, as well as intracellular events, has been recognized by the explosion of the science of glycobiology. This has been paralleled by the realization that lectins, once they have been well characterized, can be extremely useful tools for exam- ing structural changes in glycosylation and their functional consequences for human pathophysiology. Different lectins vary considerably in their degree of specificity. Some, such as wheatgerm agglutinin, have fairly broad specificity (for glucosamine or sialic acid), whereas others, such as Maackia amurensis, are specific not only for a single carbohydrate, but also for its linkage (2-3 linked sialic acid). Lectins with relatively broad specificity may be very useful as an adjunct to isolation or quantification of soluble glycoproteins, whereas lectins of known, and precise, specificity will be more useful for characterization of carbo- drate structure. We have included an appendix in Lectin Methods and Pro- cols that provides the known specificities of all lectins cited in the text.

With the invitation to edit this volume, I wanted to take the opportunity to assemble reviews on different aspects of circadian clocks and rhythms. Although most c- tributions in this volume focus on mammalian circadian clocks, the historical int- duction and comparative clocks section illustrate the importance of various other organisms in deciphering the mechanisms and principles of circadian biology. Circadian rhythms have been studied for centuries, but only recently, a mole- lar understanding of this process has emerged. This has taken research on circadian clocks from mystic phenomenology to a mechanistic level; chains of molecular events can describe phenomena with remarkable accuracy. Nevertheless, current models of the functioning of circadian clocks are still rudimentary. This is not due to the faultiness of discovered mechanisms, but due to the lack of undiscovered processes involved in contributing to circadian rhythmicity. We know for example, that the general circadian mechanism is not regulated equally in all tissues of m- mals. Hence, a lot still needs to be discovered to get a full understanding of cir- dian rhythms at the systems level. In this respect, technology has advanced at high speed in the last years and provided us with data illustrating the sheer complexity of regulation of physiological processes in organisms. To handle this information, computer aided integration of the results is of utmost importance in order to d- cover novel concepts that ultimately need to be tested experimentally.

This book describes hydration structures of proteins by combining experimental results with theoretical considerations. It is designed to introduce graduate students and researchers to microscopic views of the interactions between water and biological macromolecules and to provide them with an overview of the field. Topics on protein hydration from the past 25 years are examined, most of which involve crystallography, fluorescence measurements, and molecular dynamics simulations. In X-ray crystallography and molecular dynamics simulations, recent advances have accelerated the study of hydration structures over the entire surface of proteins. Experimentally, crystal structure analysis at cryogenic temperatures is advantageous in terms of visualizing the positions of hydration water molecules on the surfaces of proteins in their frozen-hydrated crystals. A set of massive data regarding hydration sites on protein surfaces provides an appropriate basis, enabling us to identify statistically significant trends in geometrical characteristics. Trajectories obtained from molecular dynamics simulations illustrate the motion of water molecules in the vicinity of protein surfaces at sufficiently high spatial and temporal resolution to study the influences of hydration on protein motion. Together with the results and implications of these studies, the physical principles of the measurement and simulation of protein hydration are briefly summarized at an undergraduate level. Further, the author presents recent results from statistical approaches to characterizing hydrogen-bond geometry in local hydration structures of proteins. The book equips readers to better understand the structures and modes of interaction at the interface between water and proteins. Referred to as "hydration structures", they are the subject of much discussion, as they may help to answer the question of why water is indispensable for life at the molecular and atomic level.

Starting from a comprehensive quantum mechanical description, this book introduces the optical (IR, Raman, UV/Vis, CD, fluorescence and laser spectroscopy) and magnetic resonance (1D and 2D-NMR, ESR) techniques. The book offers a timely review of the increasing interest in using spin-label ESR as an alternative structural technique for NMR or X-ray diffraction. Future aspects are treated as well, but only as an illustration of the progress of ESR in this field.

This book summarizes all the important aspects of CRLs (Cullin-RING E3 Ubiquitin Ligases), while providing details of mechanistic specifics that go beyond protein ubiquitination and neddylation. Ubiquitin ligases, including the CRLs, which are activated by neddylation, play an important role in diverse biological processes and are involved in various human diseases, particularly cancer. The book covers various topics, such as CRL structure, biology, genetics, its regulation by neddylation, its pivotal role in human disease, and its potential in drug discovery and targeted therapies. The book appeals to biochemists and biologists working in other fields, and, given the importance of CRLs in all aspects of cell biology and the great promise of targeting these complexes for therapy, is a valuable resource anyone interested in modern biology or medicine.

Introduction to Computational Proteomics introduces the field of computational biology through a focused approach that tackles the different steps and problems involved with protein analysis, classification, and meta-organization. The book starts with the analysis of individual entities and works its way through the analysis of more complex entities, from protein families to interactions, cellular pathways, and gene networks. The first part of the book presents methods for identifying the building blocks of the protein space, such as motifs and domains. It also describes algorithms for assessing similarity between proteins based on sequence and structure analysis as well as mathematical models, such as hidden Markov models and support vector machines, that are used to represent protein families and classify new instances. The second part covers methods that investigate higher order structure in the protein space through the application of unsupervised learning algorithms, such as clustering and embedding. The book also explores the broader context of proteins. It discusses methods for analyzing gene expression data, predicting protein-protein interactions, elucidating cellular pathways, and reconstructing gene networks. This book provides a coherent and thorough introduction to proteome analysis. It offers rigorous, formal descriptions, along with detailed algorithmic solutions and models. Each chapter includes problem sets from courses taught by the author at Cornell University and the Technion. Software downloads, data sets, and other material are available at biozon.org

There are 28 different collagens, with 46 unique chains, which allows for a collagen for each time and place. Some collagens are specialized for basement membrane, whereas others are the central structural component of the interstitial matrix. There are eight collagens among the 20 most abundant proteins in the body, which makes these molecules essential building blocks of tissues. In addition, lessons learned from monogenomic mutations in these proteins result in grave pathologies, exemplifying their importance in development. These molecules, and their post-translationally modified products serve as biomarkers of diseases in a range of pathologies associated with the extracellular matrix. Biochemistry of Collagens, Laminins, and Elastin: Structure, Function, and Biomarkers, Second Edition provides researchers and students current data on key structural proteins (collagens, laminins, and elastin), reviews on how these molecules affect pathologies, and information on how selected modifications of proteins can result in altered signaling properties of the original extracellular matrix component. Further, it discusses the novel concept that an increasing number of components of the extracellular matrix harbor cryptic signaling functions that may be viewed as endocrine function, and it highlights how this knowledge can be exploited to modulate fibrotic disease.

Protein Modificomics: From Modifications to Clinical Perspectives comprehensively deals with all of the most recent aspects of post-translational modification (PTM) of proteins, including discussions on diseases involving PTMs, such as Alzheimer's, Huntington's, X-linked spinal muscular atrophy-2, aneurysmal bone cyst, angelman syndrome and OFC10. The book also discusses the role PTMs play in plant physiology and the production of medicinally important primary and secondary metabolites. The understanding of PTMs in plants helps us enhance the production of these metabolites without greatly altering the genome, providing robust eukaryotic systems for the production and isolation of desired products without considerable downstream and isolation processes.

Driven by the widespread growth of proteomic practices, protein separation techniques have been refined to minimize variability, optimize particular applications, and adapt to user preferences in the analysis of proteins. Separation Methods in Proteomics provides a comprehensive examination of all major separation techniques for proteomics research. Written as a compilation of hands-on methods exemplified by the work of several recognized leaders in the field, this book may serve as a guide for selection of the optimal separation strategies to solve particular biological problems. Recent progress in the development of robust analytical techniques and instrumentation has created the need for good quality biological samples that are subject to analysis. Emphasizing the importance of sample preparation, the book explains how proteomes can be divided into smaller, less complicated "subproteomes" for individual analysis. It also highlights several hybrid approaches that take into account protein interactions. Including applications of the separation methods currently employed in proteomic analyses for both clinical and basic research, Separation Methods in Proteomics contains practical information that can enhance the current and future endeavors of scientists in proteomics, genomics, transcriptomics, biomarker discovery, and drug discovery.
