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
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.

Book Description
The Protein Protocols Handbook, Second Edition aims to provide a cross-section of analytical techniques commonly used for proteins and peptides, thus providing a benchtop manual and guide for those who are new to the protein chemistry laboratory and for those more established workers who wish to use a technique for the first time. All chapters are written in the same format as that used in the Methods in Molecular BiologyTM series. Each chapter opens with a description of the basic theory behind the method being described. The Materials section lists all the chemicals, reagents, buffers, and other materials necessary for carrying out the protocol. Since the principal goal of the book is to provide experimentalists with a full account of the practical steps necessary for carrying out each protocol successfully, the Methods section contains detailed st- by-step descriptions of every protocol that should result in the successful execution of each method. The Notes section complements the Methods material by indicating how best to deal with any problem or difficulty that may arise when using a given technique, and how to go about making the widest variety of modifications or alterations to the protocol. Since the first edition of this book was published in 1996 there have, of course, been significant developments in the field of protein chemistry.

Book Description
The membranes surrounding cells and organelles constitute their interface with the local environment. The functions of membrane proteins include cell/cell and cell/extracellular matrix recognition, the reception and transduction of extracellular signals, and the tra- port of proteins, solutes and water molecules. Abnormal membrane protein expression has profound biological effects and may, for example, underlie phenotypic and functional differences between normal and tumour cells. Moreover the accessibility, particularly of plasma proteins traversing the plasma membrane of cells, makes them of particular ut- ity to the therapeutic intervention in disease. Indeed, it is estimated that of all currently licensed pharmaceuticals, approximately 70% target proteins resident in the plasma m- brane. In theory, unbiased technologies such as proteomics have the power to de?ne patterns of membrane protein expression characteristic of distinct states of cellular development, differentiation or disease, and thereby identify novel markers of, or targets for intervention in, disease. However, although about 25% of open reading frames in fully sequenced genomes are estimated to encode integral membrane proteins, global analysis of membrane protein expression has proved problematic. Membrane protein analysis poses unique challenges at the level of extraction, solubilization, and separation in particular, and to a lesser extent of identi?cation and quantitation. These challenges have, however, fostered creativity, in- vation, and technical advances, many of which are brought together in Membrane P- teomics.
