Macromolecular Crystallization and Crystal Perfection

類似書籍推薦給您

The crystallization of proteins and nucleic acids and/or their complexes has become more highly automated but is still often a trial and error based approach. In parallel, a number of X-ray diffraction based techniques have been developed which explain the physical reasons limiting the resulting crystallographic data and thus show how that data may be improved. Crystal growth is also pivotal in neutron crystallography, which establishes the hydrogen and hydration aspects. Thus this book is aimed at addressing the science behind obtaining the best and most complete structural data possible for biological macromolecules, so that the detailed structural biology and chemistry of these important molecules emerge. Crystal imperfections such as twinning and lattice disorders, as well as multiple crystal situations, and their possible remedies, are also described. The small crystal frontier in micro-crystal crystallography, crystallites in powders and finally down to the proposed single molecule structure determination of X-ray lasers are covered. Overall this interdisciplinary book will interest crystal growers, X-ray and neutron physicists and the biological crystallographers, including graduate students.

This highly illustrated monograph provides a comprehensive study of the structure and function of proteins, nucleic acids and viruses using synchrotron radiation and crystallography. Synchrotron radiation is intense, polychromatic and finely collimated, and is highly effective for probing the structure of macromolecules. This is a fast-expanding field, and this timely monograph gives a complete introduction to the technique and its uses. Beginning with chapters on the fundamentals of macromolecular crystallography and macromolecular structure, the book goes on to review the sources and properties of synchrotron radiation, instrumentation and data collection. There are chapters on the Laue method, on diffuse X-ray scattering and on variable wavelength dispersion methods. The book concludes with a description and survey of applications including studies at high resolution, the use of small crystals, the study of large unit cells, and time-resolved crystallography (particularly of enzymes). Appendices are provided which present essential information for the synchrotron user as well as information about synchrotron facilities currently available. A detailed bibliography and reference section completes the volume. Many tables, diagrams and photographs are included.
