This book was released on 2011 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genetic code of most organisms was evolved to encode 20 amino acids. Although the ability to encode 20 amino acids provides the basis to translate proteins necessary for life, researchers are also limited to these 20 amino acids for conventional site-directed mutagenesis. The ability to encode unnatural amino acids provides researchers the ability to circumvent the limitation imposed by the genetic code. Genetically encoding unnatural amino acids provides researchers the means to not only mimic naturally occurring posttranslational modifications but also the ability to encode amino acids with new physical or chemical properties to study biological processes. The incorporation of unnatural amino acids into proteins had been developed in Escherichia coli and also in yeast. We have developed a methodology to genetically incorporate unnatural amino acids in mammalian cells in response to an amber codon (UAG). The incorporation of unnatural amino acids is high in E. coli and yeast, but the incorporation in mammalian cells is relatively low. In addition to developing the system to incorporate unnatural amino acids in mammalian cells, we have also improved suppression efficiencies by modifying the synthetase and unnatural amino acid. To incorporate unnatural amino acids in response to an amber codon, the tRNA anticodon is mutated from a GUA to a CUA. We were able to show that engineering the anticodon-binding domain of the synthetase could enhance the recognition of the tRNA and thus increased suppression efficiencies. Furthermore, by masking the carboxyl group of the amino acid by an ester group, we were able to increase the bioavailability of an unnatural amino acid to further increase suppression efficiencies. Most evolved synthetases aminoacylate unnatural amino acids that are structurally similar to the native substrate of the wild-type synthetase. We were able to adapt Methanosarcina mazei pyrrolysine synthetase (PylRS) to charge a considerable disparate amino acid from its native substrate, O-methyl-L-tyrosine. In addition, the X-ray crystal structure was solved for the evolved PylRS complexed with O-methyl-L-tyrosine at 1.75Å. This multifaceted approach provides the basis to engineer the PylRS to incorporate a significantly diverse selection of unnatural amino acids than previously anticipated.

Book excerpt: The genetic code was deciphered experimentally around 1966 and for a number of years scientists considered it to be "universal" for all forms of life. In 1981 researchers shocked the scientific community with the discovery that the code differed in mitochondria and certain other organisms, evidence that the genetic code was still evolving. This book discusses the distribution and origin of the non-universal codes and examines the possible mechanisms of code changes, making it essential reading for all those interested in evolutionary genetics.

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: By virtue of their role as catalysts of the aminoacylation reaction, the aminoacyl-tRNA synthetases ensure that the first step of translation is performed quickly and accurately. In this volume of 36 separate chapters, the many facets of this ancient and ubiquitous family are reviewed, including their surprising structural diversity, enzymology, tRNA interaction properties, and curious alternative functions. These chapters illustrate the degree to which the aminoacyl-tRNA synthetases employ a variety of mechanisms to carry out both the standard functions related to the synthesis of aminoacylated tRNA for protein synthesis, as well as the surprising functions associated with amino acid biosynthesis, cytokine function, and even the processivity of DNA replication. Other chapters explore the regulation of their synthesis, their role in disease, and their prospects as targets for antibacterial therapeutics. This monograph will be a valuable resource for all scientists interested in the fundamentals of protein synthesis from both a basic research and clinical perspective, as well as the relation of translational components to the evolution of the genetic code.
