This timely book provides a comprehensive and up-to-date account of CD spectroscopy and its application to the problems of structural biology. In particular, the newer methods of synchrotron radiation circular dichroism (SRCD) and linear dichroism (LD) are fully covered. Use of SRCD allows data between 190-160nm to be measured, where additional information content is obtained plus the ability to characterise biomolecules in diverse environments. The method has value in protein fold recognition and potential for use in structural genomics. The editors, Professor B.A. Wallace of Birkbeck College, University of London and Dr. R.W. Janes of Queen Mary College, University of London in addition to their wide research experience have extensive experience of running and teaching internationally at workshops on CD. Based on this experience, practical aspects, such as instrumentation, calibration and sampling are covered comprehensively in the book, which has been undertaken partly as a result of demand by those who participated in the workshops or by those who did not themselves participate but heard excellent reports of the workshops. The book will be of value to research workers in the general area of biophysics, to graduate students and to others entering research. Professor Wallace has been awarded the Astra Zeneca Award for 2010 by the Biochemical Society for her pioneering work on new methods of CD spectroscopy for biological studies. This book is the first volume in a new series published by IOS Press entitled Advances in Biomedical Spectroscopy, the series being edited by Dr Parvez I. Haris of De Montfort University Leicester. Each volume in the series will cover a specific spectroscopic technique for the study of biology and biological molecules.

viii The experimental research presented at the conference and reported here deals mainly with the visible wavelength region and slight extensions to either side (roughly from 150 nrn to 1000 nrn, 8. 3 eV to 1. 2 eV). A single exception was that dealing with a description of spin-resolved photoelectron spectroscopy at energies up to 40 eV (31 nm). This work was done using circularly polarized radiation emitted above and below the plane of the circulating electrons in a synchrotron ring. The device at BESSY (West Germany) in which the experiments were carried out seems to be the only one presently capable of providing circularly polarized radiation in the X--ray through vacuum ultraviolet energy range. A much more intense source is needed in this range. A possible solution was proposed which could provide not only circularly polarized photons over a wide energy range, but could in principle modulate the polarization of the beam between two orthogonal polarization states. Realization of this device, or an equivalent one, would be a vital step towards the goal of determining all components of the Mueller matrix for each spectroscopic experiment. A variety of theoretical treatments are presented describing the different phenomena emerging from the interaction of matter and polarized radiation in a wide range of energies. From this work we expect to learn what are the most useful wavelength regions and what types of samples are the most suitable for study.

The present volume contains most of the invited talks and two contributed posters of a workshop which was held in]uly 1990 within the frame of the Centro Stefano Franscini, Monte Verita at Ascona in Switzerland. The main idea has been to demonstrate that in many areas in solid state physics the use of synchrotron radiation as a powerful source for polarized uv radiation between 5 eV and about 1500 eV yields exciting new results. Furthermore, one has tried to attract a larger number of Ph D-students to bring them into contact with experienced people in the field. This tutorial aspect, I su ppose, is also in the spirit of Stefano Franscini, after whom the Centro, a joint undertaking between the Cantone Ticino and the Federal Institute of Technology in Zurich (ETHZ), has been named. Stefano Franscini, himself a dedicated teacher, has been the first member of his Canton in the Swiss Federal Council. As such he has been head of the departement of the interior and has been strongly supporting the foundation of the ETHZ. But he is also reknown, even today, as Cantonal Counceler, who has organised the elementary school system in Ticino.

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.

''Excellent and very timely....It will undoubtedly become a standard reference for the application of circular dichroism (CD) to biomolecules.'' --- Quarterly Review of Biology, March 1997 ''[T]estament to the book's utility is the fact that during the course of my review I had to 'rescue' it from the desks of graduate students on an almost daily basis. In summary, this is a great book.'' --- American Scientist ''Well documented chapters provide a very good insight into the problems surrounding the conformation of biomacromolecules...An indispensible source of information.'' --- Nahrung, 42(2), 1998 Renowned experts present the first state-of-the-art description of circular dichroism spectroscopy (CD). Chapters present in-depth discussions of the history of the field, the theory of CD for application to globular proteins, membrane proteins, peptides, nucleic acids and their interactions, carbohydrates, and instrumentation. Discussions also feature new techniques using synchrotron radiation, vibrational Raman optical activity, and vibrational CD. More than 250 illustrations supplement the text.

Biological membranes are the essential structuring elements of all living cells. Many enzymatic reactions take place at the membrane-water interface. To gain detailed insight into membrane properties, it is therefore of great importance to understand the complex nature of the interactions of membrane proteins with lipids. Lipid-Protein Interactions: Methods and Protocols provides a selection of protocols to examine protein-lipid interactions, membrane and membrane protein structure, how membrane proteins affect lipids and how they are in turn affected by the lipid bilayer and lipid properties. The methods described here are all actively used, complementary, and necessary to obtain comprehensive information about membrane structure and function. They include label-free approaches, imaging techniques and spectroscopic methodologies. Written in the 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 protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Lipid-Protein Interactions: Methods and Protocols seeks to serve both professional and novices with its wide range of the methods frequently used in this area of research.
