The companion to this book, "Protein structure: a practical approach", shows methods of determining the structure of a newly discovered protein, but that is only part of the story. This text completes the picture by providing the techniques for elucidating the functional properties of proteins, which can vary enormously, from simple structural roles to catalysis, from information transmission to energy control. This collection of tried-and-tested protocols will be applicable to many proteins, and can be performed in an average laboratory, without the need for specialized equipment.
"This edition . . . has been updated from the original 1989 edition . . . [N]ew chapters have . . . been added to reflect recent improvements in the techniques of molecular biology. . . . The ten chapters roughly focus on five areas. One of the main topics is the chemical modification of proteins . . . Another section considers techniques involved in the detection and quantification of ligand-receptor binding interactions. A third focuses on the purification and analysis of sequence-specific DNA binding proteins. . . . One of the new additions is a discussion of the techniques involved in the overexpression of cloned genes in E. coli and of those used in protein refolding. These chapters are particularly useful, as they contain warnings of numerous pitfalls as well as valuable suggestions that would aid researchers new to these areas. A final addition is a chapter on the identification of proteins by using two-dimensional electrophoresis."--The Quarterly Review of Biology
