Available in PDF, EPUB and Kindle. Book excerpt: The ability of incorporation non-canonical amino acids (ncAAs) using translation offers researchers the ability of extend the functionality of proteins and peptides for many applications including synthetic biology, biophysical and structural studies, and discovery of novel ligands. Here we describe the three projects where the addition of ncAAs to in vitro translation systems creates useful chemical biology techniques. In the first, a fluorinated histidine derivative is used to create a novel affinity tag that allows for the selective purification of peptides from a complex mixture of proteins. In the second, the high promiscuity of an editing-deficient valine-tRNA synthetase (ValRS T222P) is used to demonstrate ribosomal translation of 13 ncAAs including those with novel side chains [alpha], [alpha] disubstitutions, and cyclic[beta]amino acids. Lastly, a couple of these amino acids are integrated into the powerful ligand discovery tool of mRNA display for the discovery of helical peptide ligands.

Download or read book Genetic Code Expansion in Biochemical Investigations and Biomedical Applications written by Nanxi Wang and published by . This book was released on 2017 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic code expansion provides a powerful tool for site-specific incorporation of unnatural amino acids (unAAs) with novel biochemical and physiological properties into proteins in live cells and organisms. To achieve this, a nonsense codon suppression system, which consists of an orthogonal aminoacyl-tRNA synthetase (aaRS) and tRNA pair that specifically decodes a nonsense codon (e.g., amber codon and quadruplet codon) with an unAA but do not "cross talk" with their endogenous counterparts, was established. This Ph.D. thesis presents our efforts on evolution and application of nonsense codon suppression systems for biochemical and biomedical investigations.
Download or read book Evolution of the Genetic Code written by Shōzō Ōsawa and published by . This book was released on 1995 with total page 240 pages. Available in PDF, EPUB and Kindle. 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.
Download or read book Applications of an Expanded Genetic Code written by Eric M. Brustad and published by ProQuest. This book was released on 2008 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an ever expanding genetic code it is no longer a question of whether an unnatural amino acid can be introduced into a protein sequence, but what can be done with them. This thesis describes the introduction of novel amino acids to the genetic codes of E. coli and yeast and the applications of those amino acids towards novel protein biochemistry and the study of biomolecular structure and function. This includes the development of orthogonal protein labeling strategies that allow the site-specific attachment of biophysical probes and other molecules onto a protein surface. An unnatural ketone containing amino acid is described that allows the general and efficient introduction of fluorophores and spin probes onto a protein surface. This chemistry is exploited for the site-specific double labeling of proteins with fluorophores and the utility of this methodology is demonstrated by the examination of bacteriophage T4 lysozyme folding via single molecule fluorescence energy transfer. To expand the orthogonal chemistry presented by unnatural amino acid mutagenesis, the addition of a boronic acid containing amino acid to the genetic code of E. coli is also described. The unique chemistry of this functionality is exploited for the site-specific labeling of proteins with fluorophores through Suzuki coupling reactions as well as the formation boronic esters with diol containing compounds. This latter chemistry is also useful for the genetic encoding of carbohydrate recognition into a protein sequence as well as the development of a single step scarless protein purification methodology. The evolution of the E. coli leucyl tRNA synthetase for the site-selective introduction of methionine, cysteine and alanine analogs into proteins in yeast is also described. From this work, a single tRNA synthetase that shows promiscuous activity for over ten unnatural amino acid structures is investigated. Finally, a project investigating the role and source of reactive oxygen species in cytokine signaling is also be briefly discussed.

Download or read book Directed Evolution of and with Expanded Genetic Codes written by Chang C. Liu and published by . This book was released on 2009 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: By expanding the genetic code to allow the cotranslational incorporation of unnatural amino acids, one can site-specifically introduce unique chemical functionality into proteins in vivo. By using such expanded genetic codes in directed evolution, one can impose selection for novel protein function wherein variants containing unnatural amino acids will be selected should the unnatural amino acids confer a functional advantage. I first describe the expansion of E. coli 's genetic code for the site-specific incorporation of the unnatural amino acid sulfotyrosine and the subsequent use of this expanded genetic code for the expression and study of several proteins including sulfo-hirudin and sulfated anti-HIV antibodies. I then describe the development of a phage-based system for evolution with expanded genetic codes and the application of this system for directed evolution, through which proteins that use unnatural amino acids for enhanced function can emerge from selection. This work demonstrates the value of genetically encoding more than the 20 natural amino acids for protein engineering applications and shows that these expanded genetic codes can confer a selective advantage.

This book was released on 2019-01-05 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific advances over the past several decades have accelerated the ability to engineer existing organisms and to potentially create novel ones not found in nature. Synthetic biology, which collectively refers to concepts, approaches, and tools that enable the modification or creation of biological organisms, is being pursued overwhelmingly for beneficial purposes ranging from reducing the burden of disease to improving agricultural yields to remediating pollution. Although the contributions synthetic biology can make in these and other areas hold great promise, it is also possible to imagine malicious uses that could threaten U.S. citizens and military personnel. Making informed decisions about how to address such concerns requires a realistic assessment of the capabilities that could be misused. Biodefense in the Age of Synthetic Biology explores and envisions potential misuses of synthetic biology. This report develops a framework to guide an assessment of the security concerns related to advances in synthetic biology, assesses the levels of concern warranted for such advances, and identifies options that could help mitigate those concerns.
