By combining the tools of organic chemistry with those of physical biochemistry and cell biology, Non-Natural Amino Acids aims to provide fundamental insights into how proteins work within the context of complex biological systems of biomedical interest. The critically acclaimed laboratory standard for 40 years, Methods in Enzymology is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. With more than 400 volumes published, each Methods in Enzymology volume presents material that is relevant in today's labs -- truly an essential publication for researchers in all fields of life sciences. Demonstrates how the tools and principles of chemistry combined with the molecules and processes of living cells can be combined to create molecules with new properties and functions found neither in nature nor in the test tube Presents new insights into the molecular mechanisms of complex biological and chemical systems that can be gained by studying the structure and function of non-natural molecules Provides a "one-stop shop" for tried and tested essential techniques, eliminating the need to wade through untested or unreliable methods

Site-specific mutagenesis of DNA, developed some thirty years ago, has proven to be one of the most important advances in biology. By allowing the site-specific replacement of any amino acid in a protein with one of the other nineteen amino acids, it ushered in the new era of "Protein Engineering". The field of protein engineering has, however, evolved rapidly since then and the last fifteen years have witnessed remarkable advances through the use of new chemical, biochemical and molecular biological tools towards the synthesis and manipulation of proteins. The chapters included in this book reflect the rapid evolution of protein engineering and its many applications in basic research, biotechnology, material sciences and therapy. This book will provide the reader with an introduction to state-of the-art concepts and methods and will be of use to anyone interested in the study of proteins, in academia as well as in industry.

A method for the site-specific incorporation of unnatural amino acids into proteins in vivo would significantly facilitate studies of the cellular function of proteins, as well as make possible the biosynthesis of unnatural polymers and proteins with novel structures and activities. Our approach consists of the generation of amber suppressor tRNA/aminoacyl-tRNA synthetase pair that are not catalytically competent with all the endogenous Escherichia coli tRNAs an aminoacyl-tRNA synthetases, followed by directed evolution of such orthogonal aminoacyl-tRNA synthetases to alter their amino acid specificities. A new orthogonal suppressor tRNA/aminoacyl-tRNA synthetase pair in E. coli has been derived from the Saccharomyces cerevisiae tRNA (sub Asp) and aspartyl-tRNA syathetase, and the in vitro and in vivo characteristics of this pair were determined. In order to achieve a high specificity for the amino acid, a direct selection for site-specific incorporation of unnatural amino acids into a reporter epitope displayed on the surface of M13 phage has been developed and characterized. Under simulated selection conditions, phage particles displaying aspartate were enriched over 300-fold from a pool of phage displaying asparagine using monoclonal antibodies raised against the aspartate-containing epitope. The direct phage selection offers very high specificity for the amino acid of interest, Which cannot be achieved by conventional methods.

Translation systems and other compositions including orthogonal aminoacyl tRNA-synthetases that preferentially charge an orthogonal tRNA with an iodinated or brominated amino acid are provided. Nucleic acids encoding such synthetases are also described, as are methods and kits for producing proteins including heavy atom-containing amino acids, e.g., brominated or iodinated amino acids. Methods of determining the structure of a protein, e.g., a protein into which a heavy atom has been site-specifically incorporated through use of an orthogonal tRNA/aminoacyl tRNA-synthetase pair, are also described.
