Knowledge of the three-dimensional structure of a protein is absolutely required for the complete understanding of its function. The spatial orientation of amino acids in the active site of an enzyme demonstrates how substrate specificity is defined, and assists the medicinal chemist in the design of s- cific, tight-binding inhibitors. The shape and contour of a protein surface hints at its interaction with other proteins and with its environment. Structural ana- sis of multiprotein complexes helps to define the role and interaction of each individual component, and can predict the consequences of protein mutation or conditions that promote dissociation and rearrangement of the complex. Determining the three-dimensional structure of a protein requires milligram quantities of pure material. Such quantities are required to refine crystallization conditions for X-ray analysis, or to overcome the sensitivity limitations of NMR spectroscopy. Historically, structural determination of proteins was limited to those expressed naturally in large amounts, or derived from a tissue or cell source inexpensive enough to warrant the use of large quantities of cells. H- ever, with the advent of the techniques of modern gene expression, many p- teins that are constitutively expressed in minute amounts can become accessible to large-scale purification and structural analysis.

In the last few years there have been many exciting and innovative developments in the field of membrane protein structure and this trend is set to continue. Structural Biology of Membrane Proteins is a new monograph covering a wide range of topics with contributions from leading experts in the field. The book is split into three sections: the first discusses topics such as expression, purification and crystallisation; the second covers characterisation techniques and the final section looks at new protein structures. The book will hence have wide appeal to researchers working in and around the field and provide an up-to-date reference source. Introductory sections to each topic are accompanied by more detailed discussions for the more experienced biochemist. Detailed descriptions of experimental methods are included to demonstrate practical approaches to membrane protein structure projects. The book also offers an up-to-date reference source in addition to descriptions of new and emerging developments, including state-of-the-art techniques for solving membrane protein structures. Structural Biology of Membrane Proteins encompasses both basic introductions and detailed descriptions of themes and should appeal to a wide range of biochemical scientists, both experienced and beginner.

This detailed volume explores protocols for the production of membrane proteins in a panel of heterologous organisms for structural studies. Beginning with techniques using E. coli as a host for the overproduction and purification of membrane proteins, the book continues with chapters covering mammalian membrane protein production in yeast, insect cells, mammalian cells, as well as using virus like particles and acellular systems. Additionally, new detergents and alternatives to detergents allowing membrane protein purification for structural analyses are described. The book closes with a chapter exploring the use of microscale thermophoresis (MST) to evaluate the binding activity of heterologously expressed proteins directly in crude membrane extracts. 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 up-to-date, Heterologous Expression of Membrane Proteins: Methods and Protocols, Third Edition serves as an ideal guide for scientists aiming to produce and purify functional recombinant membrane proteins for structural studies.

Designed as a research-level guide to current strategies and methods of membrane protein production on the small to intermediate scale, this practice-oriented book provides detailed, step-by-step laboratory protocols as well as an explanation of the principles behind each method, together with a discussion of its relative advantages and disadvantages. Following an introductory section on current challenges in membrane protein production, the book goes on to look at expression systems, emerging methods and approaches, and protein specific considerations. Case studies illustrate how to select or sample the optimal production system for any desired membrane protein, saving both time and money on the laboratory as well as the technical production scale. Unique in its coverage of "difficult" proteins with large membrane-embedded domains, proteins from extremophiles, peripheral membrane proteins, and protein fragments.

While the genomic revolution has quickly led to the deposit of more than 30,000 structures in the protein data bank (PDB), less than one percent of those contributions represent membrane proteins despite the fact that membrane proteins constitute some 20 percent of all proteins. This discrepancy becomes significantly troublesome when it is coupled with the fact that 60 percent of current drugs are based on targeting this group of proteins, a trend that does not seem likely to reverse. Structural Genomics on Membrane Proteins provides an excellent overview on novel research in bioinformatics and modeling on membranes, as well as the latest technological developments being employed in expression, purification, and crystallography to obtain high-resolution structures on membrane proteins. This cutting-edge work also explains the difficulties facing researchers—both technical and ethical—that have slowed the process. Structural Genomics on Membrane Proteins provides researchers with an unprecedented look at the novel technologies that will ultimately allow them to conquer the last frontier in structural biology, leading to accelerated breakthroughs in drug discovery.

Currently, the field of mammalian membrane protein structural biology is in its infancy. Existing technologies and experiences have shown that it is possible to obtain the structures of mammalian membrane proteins if sufficient work and thought has been invested. However, there is still an urgent need to develop new methodologies and approaches to improve all aspects of this important area of biological research. Here, a series of novel technologies for the overproduction, purification and crystallisation of human membrane proteins are described which have been tested with a representative member from each of the G-protein coupled receptor (adenosine 2a receptor (A2aR)) and membrane enzyme (sterol isomerase (SI)) superfamilies. The methylotrophic yeast Pichia pastoris is an excellent host cell for the overproduction of recombinant proteins including membrane proteins of mammalian origin. However, the commercially available expression vectors are far from what is required to maximise the production levels as well as simplify the detergent extraction and purification of human membrane proteins. Here, a series of related expression constructs were made that had different combinations of tags at both ends of the recombinant protein. The final optimised expression vectors had a C3 protease-iLOV-biotin acceptor-His10 (CLBH) tag fused to the C-terminus of the recombinant protein. The -CLBH vectors gave high level production of both test proteins (one Nin - hSI; one Nout - hA2aR) that could be rapidly purified to homogeneity using a generic protocol. The position of the His10 tag did not affect the expression level of the recombinant protein. In contrast, fusion of the biotin acceptor domain to the C-terminus of the recombinant protein increased its expression by a factor of between 2-4. The biotin acceptor domain could also be fully biotinylated in vitro using recombinantly expressed biotin ligase allowing purification/immobilisation of the target protein with streptavidin

This book reviews current techniques used in membrane protein structural biology, with a strong focus on practical issues. The study of membrane protein structures not only provides a basic understanding of life at the molecular level but also helps in the rational and targeted design of new drugs with reduced side effects. Today, about 60% of the commercially available drugs target membrane proteins and it is estimated that nearly 30% of proteins encoded in the human genome are membrane proteins. In recent years much effort has been put towards innovative developments to overcome the numerous obstacles associated with the structure determination of membrane proteins. This book reviews a variety of recent techniques that are essential to any modern researcher in the field of membrane protein structural biology. The topics that are discussed are not commonly found in textbooks. The scope of this book includes: Expression screening using fluorescent proteins The use of detergents in membrane protein research The use of NMR Synchrotron developments in membrane protein structural biology Visualisation and X-ray data collection of microcrystals X-ray diffraction data analysis from multiple crystals Serial millisecond crystallography Serial femtosecond crystallography Membrane protein structures in drug discovery The information provided in this book should be of interest to anyone working in the area of structural biology.
