Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Site Specific Incorporation of Amino Acid Analogues Into Proteins In Vivo by :
Download or read book Site Specific Incorporation of Amino Acid Analogues Into Proteins In Vivo written by and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two critical requirements for developing methods for the site-specific incorporation of amino acid analogues into proteins in vivo are: (1) a suppressor tRNA that is not aminoacylated by any of the endogenous aminoacyl-tRNA synthetases (aaRSs), and (2) an aminoacyl-tRNA synthetase, which aminoacylates the suppressor tRNA but no other tRNA in the cell. Here, we describe two such aaRS/suppressor tRNA pairs, one for use in the yeast S. cerevisiae, and another for use in E. coli. The '21st synthetase/tRNA pairs' include E. coli glutaminyl-tRNA synthetase (GlnRS) along with an amber suppressor derived from human initiator tRNA, for use in yeast, and mutants of the yeast tyrosyl-tRNA synthetase (TyrRS) along with an amber suppressor derived from E. coli initiator tRNA, for use in E. coli. The suppressor tRNAs are aminoacylated in vivo only in the presence of the heterologous aaRSs and the aminoacylated tRNAs function efficiently in suppression of amber codons. Plasmids carrying the E. coli GlnRS gene can be stably maintained in yeast.

Download or read book Exploring and Expanding the Protein Universe with Non-Canonical Amino Acids written by Gustavo Fuertes and published by Frontiers Media SA. This book was released on 2023-11-01 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The site-specific incorporation of unnatural or non-canonical amino acids (ncAAs) into proteins is a universally important tool for systems bioengineering at the interface of chemistry, biology, and biotechnology. The synergistic use of ncAA and related technologies (e.g. Xeno nucleic acids) should enable: i) New opportunities to manipulate, design and elucidate protein structure, dynamics, and function. ii) A deeper understanding of natural and evolved translational systems and their importance for artificial biology. iii) The synthesis of novel biopolymers, creating a solid basis for synthetic cells, which is also an important technology in the production of new classes of medically relevant protein-based scaffolds. Research on reprogrammed protein translation has now reached an experimental and intellectual maturity: more than 200 ncAA (i.e. more than ten times larger variety than standard amino acids) have been introduced into proteins using different routes: genetic code expansion (GCE), selective pressure incorporation (SPI), chemical mutagenesis, protein semi-synthesis, and peptide synthesis.

Available in PDF, EPUB and Kindle. Book excerpt: Our objective is to develop general methods for the site-specific incorporation of amino acid analogues into proteins in bacterial and in eukaryotic cells. The approach consists of the use of an amber suppressor transfer RNA (tRNA) aminoacylated with an amino acid analogue, with the help of a mutant aminoacyl-tRNA synthetase, to insert the amino acid analogue at a specific site in a protein. The site of insertion of the analogue is specified by an appropriately placed amber termination codon within the gene for the protein of interest. This approach has two key requirements: (1) an amber suppressor tRNA, which can not be aminoacylated by any of the endogenous aminoacyltRNA synthetases and (2) an aminoacyi-tRNA synthetase, which aminoacylates the amber suppressor tRNA but no other tRNA in the cell. Therefore, an important first goal is to identify such a 21st aminoacyl-tRNA synthetase tRNA synthetase-amber tRNA pair. This goal has been achieved. Several mutations have been introduced into yeast tyrosyl-tRNA synthetase (TyrRS) for isolating mutants that incorporate iodotyrosine into tRNA instead of tyrosine. Work on an alternative approach applicable to mammalian cells has led to a possible general approach for the introduction of two different amino acid analogues into a protein.
Book Synopsis Protein Evolution in the Presence of an Unnatural Amino Acid by : Amrita Singh

Available in PDF, EPUB and Kindle. Book excerpt: The field of protein engineering has been greatly augmented by the expansion of the genetic code using unnatural amino acids as well as the development of cell-free synthesis systems with high protein yield. Cell-free synthesis systems have improved considerably since they were first described almost 40 years ago. Residue specific incorporation of non-canonical amino acids into proteins is usually performed in vivo using amino acid auxotrophic strains and replacing the natural amino acid with an unnatural amino acid analog. Herein, we present an amino acid depleted cell-free protein synthesis system that can be used to study residue specific replacement of a natural amino acid by an unnatural amino acid analog. This system combines high protein expression yields with a high level of analog substitution in the target protein. To demonstrate the productivity and efficacy of a cell-free synthesis system for residue-specific incorporation of unnatural amino acids in vitro, we use this system to show that 5-fluorotryptophan and 6-fluorotryptophan substituted streptavidin retain the ability to bind biotin despite protein wide replacement of a natural amino acid for the amino acid analog. We envisage this amino acid-depleted cell-free synthesis system being an economical and convenient format for the high-throughput screening of a myriad of amino acid analogs with a variety of protein targets for the study and functional characterization of proteins substituted with unnatural amino acids when compared to the currently employed in vivo format. We use this amino acid depleted cell-free synthesis system for the directed evolution of streptavidin, a protein that finds wide application in molecular biology and biotechnology. We evolve streptavidin using in vitro compartmentalization in emulsions to bind to desthiobiotin and find, at the conclusion of our experiment, that our evolved streptavidin variants are capable of binding to both biotin and desthiobiotin equally well. We also discover a set of mutations for streptavidin that are potentially powerful stabilizing mutations that we believe will be of great use to the greater research community.
