This book serves as an introduction to protein structure and function. Starting with their makeup from simple building blocks, called amino acids, the 3-dimensional structure of proteins is explained. This leads to a discussion how misfolding of proteins causes diseases like cancer, various encephalopathies, or diabetes. Enzymology and modern concepts of enzyme kinetics are then introduced, taking into account the physiological, pharmacological and medical significance of this often neglected topic. This is followed by thorough coverage of hæmoglobin and myoglobin, immunoproteins, motor proteins and movement, cell-cell interactions, molecular chaperones and chaperonins, transport of proteins to various cell compartments and solute transport across biological membranes. Proteins in the laboratory are also covered, including a detailed description of the purification and determination of proteins, as well as their characterisation for size and shape, structure and molecular interactions. The book emphasises the link between protein structure, physiological function and medical significance. This book can be used for graduate and advanced undergraduate classes covering protein structure and function and as an introductory text for researchers in protein biochemistry, molecular and cell biology, chemistry, biophysics, biomedicine and related courses. About the author: Dr. Buxbaum is a biochemist with interest in enzymology and protein science. He has been working on the biochemistry of membrane transport proteins for nearly thirty years and has taught courses in biochemistry and biomedicine at several universities.

The Sixth International Meeting on Cholinesterases and Related Proteins, Choli nesterases '98, was organized by Palmer Taylor and his associates at the University of California-San Diego and convened in La Jolla, California, USA, in March of 1998. This was the first conference of the series to be held in the United States, let alone on the Pa cific Rim. Nearly 200 delegates from twenty countries-from Asia, Australia, Europe, and North and South America-heard 75 oral presentations and viewed 90 posters on current research on cholinesterases and related proteins. The meeting framework was structured to include two days of plenary sessions, followed by two days of concurrent sessions and workshops in specific areas. Communication at the concurrent sessions was facilitated by the conference settings of the Martin Johnson House, on a scenic bluff overlooking the blue Pacific Ocean, and the San Diego Supercomputer Center, which enabled projection and rotation of protein structures in three dimensions for a large audience. This book is the compilation of the presentations at the Sixth International Meeting on Cholinesterases and Related Proteins into a volume that describes recent investigations on the structure, catalytic and non-catalytic functions of acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), and related proteins, as well as studies on the molecular and cellular biology of these enzymes and the genes that encode them.

This book is about protein structural bioinformatics and how it can help understand and predict protein function. It covers structure-based methods that can assign and explain protein function based on overall folds, characteristics of protein surfaces, occurrence of small 3D motifs, protein-protein interactions and on dynamic properties. Such methods help extract maximum value from new experimental structures, but can often be applied to protein models. The book also, therefore, provides comprehensive coverage of methods for predicting or inferring protein structure, covering all structural classes from globular proteins and their membrane-resident counterparts to amyloid structures and intrinsically disordered proteins. The book is split into two broad sections, the first covering methods to generate or infer protein structure, the second dealing with structure-based function annotation. Each chapter is written by world experts in the field. The first section covers methods ranging from traditional homology modelling and fold recognition to fragment-based ab initio methods, and includes a chapter, new for the second edition, on structure prediction using evolutionary covariance. Membrane proteins and intrinsically disordered proteins are each assigned chapters, while two new chapters deal with amyloid structures and means to predict modes of protein-protein interaction. The second section includes chapters covering functional diversity within protein folds and means to assign function based on surface properties and recurring motifs. Further chapters cover the key roles of protein dynamics in protein function and use of automated servers for function inference. The book concludes with two chapters covering case studies of structure prediction, based respectively on crystal structures and protein models, providing numerous examples of real-world usage of the methods mentioned previously. This book is targeted at postgraduate students and academic researchers. It is most obviously of interest to protein bioinformaticians and structural biologists, but should also serve as a guide to biologists more broadly by highlighting the insights that structural bioinformatics can provide into proteins of their interest.

The prediction of the conformation of proteins has developed from an intellectual exercise into a serious practical endeavor that has great promise to yield new stable enzymes, products of pharmacological significance, and catalysts of great potential. With the application of predic tion gaining momentum in various fields, such as enzymology and immunology, it was deemed time that a volume be published to make available a thorough evaluation of present methods, for researchers in this field to expound fully the virtues of various algorithms, to open the field to a wider audience, and to offer the scientific public an opportunity to examine carefully its successes and failures. In this manner the practitioners of the art could better evaluate the tools and the output so that their expectations and applications could be more realistic. The editor has assembled chapters by many of the main contributors to this area and simultaneously placed their programs at three national resources so that they are readily available to those who wish to apply them to their personal interests. These algorithms, written by their originators, when utilized on pes or larger computers, can instantaneously take a primary amino acid sequence and produce a two-or three-dimensional artistic image that gives satisfaction to one's esthetic sensibilities and food for thought concerning the structure and function of proteins. It is in this spirit that this volume was envisaged.

This volume surveys the current status of many of the important methods and approaches which are central to the study of protein structure and function. Many of the articles in this volume are written to emphasize the general utility of the method or approach which is at its core, and to provide sufficient literature references to enable the reader to adapt the method or approach to other applications. It is hoped that this volume will provide a source from which newcomers as well as experienced scient ists may becom& more familiar with recent developments and future trends in some of the important areas of protein research. The articles which comprise this book are selected proceedings from the Symposium of American Protein Chemists, which was held in San Diego, California, September 30 to October 3, 1985. The goal of the organizers of this first symposium was to provide a forum for discussion and inter action among scientists whose interests span the broad spectrum of protein structure and function research. The concept and timing of the symposium well received as evidenced by the approximately 500 delegates to the was symposium. The inaugural meeting was marked by a strong scientific pro gram with over 140 papers presented in either a lecture or poster format.

The existence and functioning of intrinsically disordered proteins (IDPs) challenge the classical structure-function paradigm that equates function with a well-defined 3D structure. Uncovering the disordered complement of proteomes and understanding their functioning can extend the structure-function paradigm to herald new breakthroughs in drug development. Structure and Function of Intrinsically Disordered Proteins thoroughly covers the history up to the latest developments in this field. After examining the principles of protein structure, the classical paradigm, and the history of structural disorder, the book focuses on physical techniques for the identification and characterization of IDPs. It discusses proteomic and bioinformatic approaches and shows how IDPs behave under crowding conditions in living cells. The next several chapters describe the structure, correlating biological processes, and molecular mechanisms of IDPs. The author also explores the evolutionary advancement of structural disorder in proteomes and possible ways of extending the structure-function paradigm to encompass both ordered and disordered states of proteins. He concludes with discussions on the involvement of IDPs in various diseases and how to establish rational drug design through detailed characterization of IDPs. Although drug discovery rates have leveled off, new insight generated by the study of IDPs may offer fresh strategies for drug development. This work illustrates how these proteins defy the structure-function paradigm and play important regulatory and signaling roles.

Structure and Function of Membrane Proteins documents the proceedings of the International Symposium on Structure and Function of Membrane Proteins held in Selva di Fasano on May 23-26, 1983. This compilation makes it possible to obtain more information on the structure of membrane proteins, determining the structure in order to understand the function, and mechanism of action that is only understood by knowledge of the atomic structure. The gathering of data on the function of membrane proteins prior to knowledge of their structure is valuable for characterizing and defining the proteins. Once the structure is known, another stage of research will penetrate to the functional assignments of the structure. Other topics covered include the physical methods for the structure-function relationship; identification and mapping of sites in membrane proteins; and primary structure of transport proteins. Tertiary structure and molecular shape of membrane proteins and structure-function relationship in membrane proteins are also examined. This book is a good source of information for students and individuals conducting research on biochemistry, specifically on membrane proteins.

The Proteins, Third Edition, Volume V discusses the unifying concepts of protein chemistry. This volume contains three chapters that cover specific protein classes, namely, glycoproteins and cyclopeptides. Chapter 1 deals first with the purification and characterization of the N- and O-linked glycosidic groups of glycoproteins. This chapter then describes the oligosaccharide catabolism and the roles of lysosomal hydrolases, and of functions of glycoproteins as mediated by their oligosaccharide groups. Chapter 2 begins with a detailed review of ultraviolet and visible spectroscopic techniques along with their basic principles, as well as theoretical calculations of peptide spectra. This chapter then considers absorption spectroscopy, optical rotary dispersion, and circular dichroism, followed by a discussion on the use of these methods on the secondary, tertiary, and quaternary structures of proteins in solution. Infrared and Raman spectroscopy and their applications to secondary structure analysis of proteins are also included in this chapter. Chapter 3 provides a critical review of naturally occurring and synthetic cyclopeptides, a unique group of molecules that include diverse biological compounds such as toxins, hormones, regulators of ion transport, and antibiotics. Organic chemists and researchers, teachers and undergraduate students will find this book invaluable.

Structural genomics is the systematic determination of 3-dimensional structures of proteins representative of the range of protein structure and function found in nature. The goal is to build a body of structural information that will predict the structure and potential function for almost any protein from knowledge of its coding sequence. This is essential information for understanding the functioning of the human proteome, the ensemble of tens of thousands of proteins specified by the human genome. While most structural biologists pursue structures of individual proteins or protein groups, specialists in structural genomics pursue structures of proteins on a genome wide scale. This implies large scale cloning, expression and purification. One main advantage of this approach is economy of scale. Key Features *Examines the three dimensional structure of all proteins of a given organism, by experimental methods such as X-ray crystallography and NMR spectroscopy * Looks at structural genomics as a foundation of drug discovery as discovering new medicines is becoming more challenging and the pharmaceutical industry is looking to new technologies to help in this mission
