"When the history of the 20th century science is written, surely the chapter on determining the structure of molecules by X-ray crystallography, NMR, and electron microscopy will be one of the most prominent with the structure of proteins and viruses being the culminating glory. No current book illustrates and explains these glories more effectively and concisely than Branden and Tooze's second edition of their fine text."
Structure

"This is a thorough review of current knowledge in this field. The text is rather detailed, but is richly illustrated with clear, good quality, colour diagrams, accompanied by comprehensive and informative labels."
Journal of Biological Education

"The text by Branden and Tooze is an outstanding overview of knowledge in a very rapidly growing field. It is really the only book of its kind, and it should be an essential part of any undergraduate (or graduate) curriculum. By describing particular protein structures in the context of their functional properties, the authors have ensured a clear framework of biological relevance."
