Book Description
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. Students will find carefully prepared overviews of basic ideas and advanced protein scientists will find the level of detail required to apply the material directly to their day to day work. Chapters 4, 5, 6, 8 and 9 of this book are published open access under a CC BY 4.0 license at link.springer.com.

Book Description
In this present volume, different approaches are detailed to produce membrane proteins, purify them, study their function, determine their structure, and model them in membrane. Since every membrane protein behaves mostly in a unique way /fashion, knowledge of guidelines and tricks may help to increase chances to express, purify and characterize a peculiar membrane protein. Production of correctly folded protein remains a challenge. Moreover, getting a functional and stable protein requires to optimize membrane mimicking environments that can be detergent or artificial membranes. In some cases, the finding of the correct ligand which will stabilize the desired conformation is needed. In other cases, stabilization can be obtained using specific antibodies. This volume also presents different techniques to analyze the functional status of membrane proteins. Written in the highly successful Methods in Molecular Biology series format, chapters in Membrane Protein Structure and Function Characterization: Methods and Protocols provide different techniques to analyze the functional and structural status of membrane proteins. 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 practical, Membrane Protein Structure and Function Characterization: Methods and Protocols aims to ensure successful results in the further study of this vital field.

Book Description
Membrane proteins, representing nearly 40% of all proteins, are key components of cells involved in many cellular processes, yet only a small number of their structures have been determined. Membrane Protein Structure Determination: Methods and Protocols presents many detailed techniques for membrane protein structure determination used today by bringing together contributions from top experts in the field. Divided into five convenient sections, the book covers various strategies to purify membrane proteins, approaches to get three dimensional crystals and solve the structure by x-ray diffraction, possibilities to gain structural information for a membrane protein using electron microscopy observations, recent advances in nuclear magnetic resonance (NMR), and molecular modelling strategies that can be used either to get membrane protein structures or to move from atomic structure to a dynamic understanding of a molecular functioning mechanism. Written in the highly successful Methods in Molecular BiologyTM 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. Comprehensive and easy to use, Membrane Protein Structure Determination: Methods and Protocols serves as an ideal reference for scientists seeking to further our knowledge of these vital and versatile proteins as well as our overall understanding of the complicated world of cell biology.

Book Description
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.

Book Description
Structure determination of membrane proteins by solution nuclear magnetic resonance spectroscopy require that they can be incorporated into detergent micelles in order to ensure that they are maintained in a folded, water-soluble state. However, detergent molecules produce micelle-protein complexes that pose unique challenges for solution NMR studies. To improve the spectroscopic properties of these complexes, it is possible to use specific isotope labeling strategies developed for the study of large water-soluble proteins by solution NMR. Specifically, the use of a highly deuterated sample that retains protons only in the Val, Leu and Ile (delta1) methyl groups has the potential to be used to determine structures of polytopic helical membrane proteins. However, while the quality of structure that can be obtained from this approach has been examined for water-soluble proteins, its utility for this class of membrane proteins has not been systematically investigated. This thesis evaluates the utility of this method for structure determination of membrane proteins by exploring structure calculation strategies from simulated NMR data sets from membrane proteins of known structure. Here I present results for a set of membrane proteins that consist of pairs or bundles of hydrophobic alpha-helices. I analyzed the impact of intra- and inter-helical NOEs on structure quality for samples specifically labeled with protons only at the methyl and amide positions In addition, I also explored the role of dihedral angles and residual dipolar couplings in an effort to find general trends to improve the accuracy of structures for polytopic a-helical membrane proteins. Based on the results of these calculations it appears that obtaining a uniform distribution of inter-helical NOES and accurately identifying transmembrane helices for dihedral angle restraints are the most important factors determining the accuracy of these simulated membrane protein structures. These results should help to guide future structure determinations for polytopic alpha-helical membrane proteins of unknown structure.
