Electrophoresis is the leading method among those used in the investigation of pro teins and nucleic acids. A paper on the study of these biopolymers without recourse to electrophoresis at each fractionation or characterization step is very unlikely to be encountered in the current scientific literature. This method enables separation of macromolecules according to characteristic features such as size (or molecular weight), shape, secondary structure and electric charge and these parameters can in fluence electrophoretic properties either separately or jointly. The physical background of this method is as follows. Macromolecules in a buf fer solution may become charged; the sign and magnitude of the total electrical charge depending on the pH of the medium. When such a solution is put into an insulated channel, e.g. in a glass tube, and a voltage applied at the ends of the chan nel, an electric field will be formed and direct current will pass through solution. The field strength can be defined as the potential difference at the ends of the chan nel (or its section) with respect to its length (v/cm). When exposed to an electrical field macromolecules will migrate towards the cathode or the anode according to their net charge and frictional force will limit the migration velocity.

Structural Bioinformatics was the first major effort to show the application of the principles and basic knowledge of the larger field of bioinformatics to questions focusing on macromolecular structure, such as the prediction of protein structure and how proteins carry out cellular functions, and how the application of bioinformatics to these life science issues can improve healthcare by accelerating drug discovery and development. Designed primarily as a reference, the first edition nevertheless saw widespread use as a textbook in graduate and undergraduate university courses dealing with the theories and associated algorithms, resources, and tools used in the analysis, prediction, and theoretical underpinnings of DNA, RNA, and proteins. This new edition contains not only thorough updates of the advances in structural bioinformatics since publication of the first edition, but also features eleven new chapters dealing with frontier areas of high scientific impact, including: sampling and search techniques; use of mass spectrometry; genome functional annotation; and much more. Offering detailed coverage for practitioners while remaining accessible to the novice, Structural Bioinformatics, Second Edition is a valuable resource and an excellent textbook for a range of readers in the bioinformatics and advanced biology fields. Praise for the previous edition: "This book is a gold mine of fundamental and practical information in an area not previously well represented in book form." —Biochemistry and Molecular Education "... destined to become a classic reference work for workers at all levels in structural bioinformatics...recommended with great enthusiasm for educators, researchers, and graduate students." —BAMBED "...a useful and timely summary of a rapidly expanding field." —Nature Structural Biology "...a terrific job in this timely creation of a compilation of articles that appropriately addresses this issue." —Briefings in Bioinformatics

In much of biology, the search for understanding the relation between structure and function is now taking place at the macromolecular level. Proteins, nucleic acids, and polysaccharides are macromolecule--polymers formed from families of simpler subunits. Because of their size and complexity, the polymers are capable of both inter- and intramolecular interactions. These interactions confer upon the polymers distinctive three-dimensional shapes. These tertiary configurations, in turn, determine the function of the macromolecule. Computers have become so inextricably involved in empirical studies of three-dimensional macromolecular structure that mathematical modeling, or theory, and experimental approaches are interrelated aspects of a single enterprise.
