  • Braking the Genetic Code by Nierenberg
    1 REVIEW The Invention of Proteomic Code and mRNA Assisted Protein Folding. by Jan C. Biro Homulus Foundation, 612 S Flower St. #1220, 90017 CA, USA. [email protected] Keywords: Gene, code, codon, translation, wobble-base, Abbreviations (excluding standard abbreviations: 2 Abstract Background The theoretical requirements for a genetic code were well defined and modeled by George Gamow and Francis Crick in the 50-es. Their models failed. However the valid Genetic Code, provided by Nirenberg and Matthaei in 1961, ignores many theoretical requirements for a perfect Code. Something is simply missing from the canonical Code. Results The 3x redundancy of the Genetic code is usually explained as a necessity to increase the resistance of the mutation resistance of the genetic information. However it has many additional roles. 1.) It has a periodical structure which corresponds to the physico-chemical and structural properties of amino acids. 2.) It provides physico-chemical definition of codon boundaries. 3.) It defines a code for amino acid co-locations (interactions) in the coded proteins. 4.) It regulates, through wobble bases the free folding energy (and structure) of mRNAs. I shortly review the history of the Genetic Code as well as my own published observations to provide a novel, original explanation of its redundancy. Conclusions The redundant Genetic Code contains biological information which is additional to the 64/20 definition of amino acids. This additional information is used to define the 3D structure of coding nucleic acids as well as the coded proteins and it is called the Proteomic Code and mRNA Assisted Protein Folding.

Steitz and Ada E. Yonath for their studies of the structure and function of the ribosome. Their scientific contributions and the historical context are summarized below. Brief introduction to the ribosome The ribosome and the central dogma. The genetic information in living systems is stored in the genome sequences of their DNA (deoxyribonucleic acid). A large part of these sequences encode proteins which carry out most of the functional tasks in all extant organisms. The DNA information is made available by transcription of the genes to mRNAs (messenger ribonucleic acids) that subsequently are translated into the various amino acid sequences of all the proteins of an organism. This is the central dogma (Crick, 1970) of molecular biology in its simplest form (Figure 1) DNA () gene →transcription RNA ( mRNA )→translation Protein ( peptide sequence) Figure 1. The central dogma revisited. The genetic information in DNA is preserved by replication of the genome (Watson and Crick, 1953a, b) carried out by DNA polymerase (Kornberg, 1969) so that each daughter cell can receive one genome copy at every cell division.

  • Ribonucleobase Interactions and Their Potential for Ribosome-Free Encoding
    www.nature.com/scientificreports OPEN Cross-species conservation of complementary amino acid- ribonucleobase interactions and Received: 31 March 2015 Accepted: 02 November 2015 their potential for ribosome-free Published: 10 December 2015 encoding John G. D. Cannon1, Rachel M. Sherman2,3, Victoria M. Y. Wang4,† & Grace A. Newman5 The role of amino acid-RNA nucleobase interactions in the evolution of RNA translation and protein- mRNA autoregulation remains an open area of research. We describe the inference of pairwise amino acid-RNA nucleobase interaction preferences using structural data from known RNA- protein complexes. We observed significant matching between an amino acid’s nucleobase affinity and corresponding codon content in both the standard genetic code and mitochondrial variants. Furthermore, we showed that knowledge of nucleobase preferences allows statistically significant prediction of protein primary sequence from mRNA using purely physiochemical information. Interestingly, ribosomal primary sequences were more accurately predicted than non-ribosomal sequences, suggesting a potential role for direct amino acid-nucleobase interactions in the genesis of amino acid-based ribosomal components. Finally, we observed matching between amino acid- nucleobase affinities and corresponding mRNA sequences in 35 evolutionarily diverse proteomes. We believe these results have important implications for the study of the evolutionary origins of the genetic code and protein-mRNA cross-regulation. Despite having been discovered more than 50 years ago1,2 and studied for nearly as long3, the evolutionary basis of the universal genetic code remains an elusive challenge4. Even before the discovery of messenger RNA (mRNA) and the elucidation of the genetic code George Gamow proposed a stereochemical hypothesis based on the then recently determined structure of DNA5.

  • On the Uniqueness of the Standard Genetic Code
    life Article On the Uniqueness of the Standard Genetic Code Gabriel S. Zamudio and Marco V. José * Theoretical Biology Group, Instituto de Investigaciones Biomédicas, Universidad Nacional Autónoma de México, México D.F. 04510, Mexico; [email protected] * Correspondence: [email protected]; Tel.: +52-5562-3894 Academic Editor: Koji Tamura Received: 15 December 2016; Accepted: 8 February 2017; Published: 13 February 2017 Abstract: In this work, we determine the biological and mathematical properties that are sufficient and necessary to uniquely determine both the primeval RNY (purine-any base-pyrimidine) code and the standard genetic code (SGC). These properties are: the evolution of the SGC from the RNY code; the degeneracy of both codes, and the non-degeneracy of the assignments of aminoacyl-tRNA synthetases (aaRSs) to amino acids; the wobbling property; the consideration that glycine was the first amino acid; the topological and symmetrical properties of both codes. Keywords: RNY code; Standard genetic code; evolution of the genetic code; frozen code; degeneracy; aminoacyl-tRNA synthetases; symmetry 1. Introduction A fundamental feature of all life forms existing on Earth is that, with several minor exceptions, they share the same standard genetic code (SGC). This universality led Francis Crick to propose the frozen accident hypothesis [1], i.e., the SGC does not change. According to Crick [1], the SGC code remained universal because any change would be lethal, or would have been very strongly selected against and extinguished. The astonishing diversity of living beings in the history of the biosphere has not been halted by a frozen SGC. The inherent structure of the frozen SGC, in concert with environmental influences, has unleashed life from determinism.

Degeneracies in physical degeneracy of the genetic code can be lifted by environmental and biological systems can be lifted by external perturbations, thus perturbations and how degeneracy lifting could provide a general allowing degenerate systems to exhibit a wide range of behaviors. strategy to adapt protein synthesis to environmental changes. Here we show that the degeneracy of the genetic code is lifted by environmental perturbations to regulate protein levels in living Results cells. By measuring protein synthesis rates from a synthetic reporter DegeneracyLiftinguponAminoAcidLimitation.We considered library in Escherichia coli,wefind that environmental perturbations, synonymous codons for seven amino acids: Leu, Arg, Ser, Pro, Ile, such as reduction of cognate amino acid supply, lift the degeneracy Gln, and Phe. This set of seven amino acids is representative of of the genetic code by splitting codon families into a hierarchy of the degeneracy of the genetic code, in that it includes six-, four-, robust and sensitive synonymous codons.

Synthetases help to ensure accurate translation of the genetic code by using both highly accurate cognate substrate recognition and stringent proofreading of non-cognate products. While alterations in the quality control mechanisms of synthetases are generally detrimental to cellular viability, recent studies suggest that in some instances such changes facilitate adaption to stress conditions. Beyond their central role in translation, synthetases are also emerging as key players in an increasing number of other cellular processes, with far reaching consequences in health and disease. The biochemical versatility of the synthetases has also proven pivotal in efforts to expand the genetic code, further emphasizing the wide-ranging roles of the aminoacyl-tRNA synthetase family in synthetic and natural biology.

  • The Death of Francis Crick: the End of a Golden Age in Biology
    Commentary The death of Francis Crick: the end of a golden age in biology Born in 1916, Francis Harry Compton Crick studied physics at University College, London, where he devoted his first scientific efforts to studying the viscosity of water at high temperatures. During the war, he participated in the development of ‘noncontact’ magnetic and acoustic mines. Like many other young physicists, he switched to biology after the Second World War, bored by the now dull studies pursued in physics, and attracted by the new frontier of knowledge that was biology, a discipline where the concepts and techniques of physics were desperately needed. He spent two years at the Strangeways Laboratory in Cambridge studying the physical properties of cytoplasm, and joined the Medical Research Unit at Cavendish laboratory headed by Max Perutz to study protein structure by X-ray diffraction studies. The decision he made with Jim Watson to focus on the structure of DNA, and the huge impact this structure had on the development of molecular biology, are well known. Francis Crick received with Jim Watson and Maurice Wilkins the Nobel Prize in Physiology or Medicine in 1962 for this discovery. To consider that determining the structure of DNA was the right way to understand the power of genes was a brilliant piece of foresight at a time when the results of Oswald Avery showing that genes were made of DNA were largely ignored. Watson was the leader in the construction of the model, adopting a strategy previously used by Linus Pauling for the study of proteins. Given his excellent knowledge of crystallography and X-ray diffraction, Francis Crick had all the skills required to pro- vide the firm materials for the elaboration of the model and to relate it to the X-ray diffraction pattern obtained by Rosalind Franklin.

  • BIOCHEMICAL PROPERTIES of CLASS I LYSYL-Trna
    BIOCHEMICAL PROPERTIES OF CLASS I LYSYL-tRNA SYNTHETASE DISSERTATION A Thesis Presented in Partial Fulfillment of the Requirements for The Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Jeffrey David Levengood, B.S. ***** The Ohio State University 2007 Dissertation Committee: Professor Michael Ibba, Adviser Professor Russ Hille Approved by Professor John Reeve _______________________________________ Professor Zucai Suo Adviser The Ohio State Biochemistry Graduate Program ABSTRACT The family of aminoacyl-tRNA synthetases (aaRSs) performs the essential cellular function of charging tRNA molecules with their cognate amino acids. This enzyme family can be divided into two unrelated classes with each evolving from different origins. Lysyl-tRNA synthetase (LysRS) is the only synthetase known to have a form in each class. The class I form (LysRS1) is found in most archaea and a few bacteria while the class II form (LysRS2) is found in all eucarya, most bacteria, and a few archaea. Steady-state kinetics were used to study the mechanisms which LysRS1 employs to recognize its substrates. The binding of both amino acid and tRNA were examined. The binding of lysine was analyzed by studying the ability of several lysine analogues to inhibit the aminoacylation reaction. It was found that the R-group plays a critical role in discrimination rather than the functional groups at the α-carbon. Within the R-group, the size of the chain was a very important point for discrimination. The binding of tRNALys was examined using both LysRS, mutated based on the modeled tRNALys bound to LysRS1, and tRNALys with mutations in the anticodon.
