Proteins play a central role in all biological systems. They fulfill numerous functions which depend upon their complex three-dimensional structures, maintained by a multitude of interactions. This book examines important advances in the understanding of protein structure diversity, the basis of protein stability, and the important relationship between structure and function. These findings have been made possible through the application of key techniques such as X-ray crystallography, NMR, and protein engineering. Protein Structure: In Focus provides comprehensive coverage of this subject for students in biochemistry, biophysics, molecular biology, and related courses, and will also be of great interest to researchers requiring an introduction to this field.Darby, N. J. is the author of 'Protein Structure' with ISBN 9780199633104 and ISBN 019963310X.
