Engineered transfer RNAs for suppression of premature termination codons

open access: yesNature Communications, 2019
Premature termination codon suppression therapy could be used to treat a range of genetic disorders. Here the authors present a high-throughput cell-based assay to identify anticodon engineered tRNAs with high suppression activity.

The Triplet Genetic Code had a Doublet Predecessor

open access: yes, 2004
Information theoretic analysis of genetic languages indicates that the naturally occurring 20 amino acids and the triplet genetic code arose by duplication of 10 amino acids of class-II and a doublet genetic code having codons NNY and anticodons ...

5\u27-Terminal nucleotide variations in human cytoplasmic tRNAHisGUG and its 5\u27-halves. [PDF]

open access: yes, 2017
Transfer RNAs (tRNAs) are fundamental adapter components of translational machinery. tRNAs can further serve as a source of tRNA-derived noncoding RNAs that play important roles in various biological processes beyond translation.

Release of initiation factors from 48S complexes during ribosomal subunit joining and the link between establishment of codon-anticodon base-pairing and hydrolysis of eIF2-bound GTP.

open access: yesGenes & Development, 2004
The 40S subunit in 48S complexes formed at the initiation codon of mRNA is bound to eukaryotic initiation factor (eIF) 3, eIF1, eIF1A, and an eIF2/GTP/Met-tRNAi(Met) ternary complex and can therefore not join a 60S subunit directly to form an 80S ...

Defective i6A37 modification of mitochondrial and cytosolic tRNAs results from pathogenic mutations in TRIT1 and its substrate tRNA.

open access: yesPLoS Genetics, 2014
Identifying the genetic basis for mitochondrial diseases is technically challenging given the size of the mitochondrial proteome and the heterogeneity of disease presentations.

Application of a periodic table for the genetic code to influenza A/H3N2 virus [PDF]

open access: yes, 2007
If biologists can utilize a table to have access to biological phenomena in the manner analogous to the periodic table for chemical elements, they may get hold of a directing post in life science.

Unconventional decoding of the AUA codon as methionine by mitochondrial tRNAMet with the anticodon f5CAU as revealed with a mitochondrial in vitro translation system

open access: yesNucleic Acids Research, 2009
Mitochondrial (mt) tRNAMet has the unusual modified nucleotide 5-formylcytidine (f5C) in the first position of the anticodon. This tRNA must translate both AUG and AUA as methionine.

Evidence from glycine transfer RNA of a frozen accident at the dawn of the genetic code

open access: yesBiology Direct, 2008
Background Transfer RNA (tRNA) is the means by which the cell translates DNA sequence into protein according to the rules of the genetic code. A credible proposition is that tRNA was formed from the duplication of an RNA hairpin half the length of the ...

Towards Understanding the Origin of Genetic Languages

open access: yes, 2008
Molecular biology is a nanotechnology that works--it has worked for billions of years and in an amazing variety of circumstances. At its core is a system for acquiring, processing and communicating information that is universal, from viruses and bacteria

The enigmatic mitochondrial genome of Rhabdopleura compacta (Pterobranchia) reveals insights into selection of an efficient tRNA system and supports monophyly of Ambulacraria

open access: yesBMC Evolutionary Biology, 2011
Background The Hemichordata comprises solitary-living Enteropneusta and colonial-living Pterobranchia, sharing morphological features with both Chordata and Echinodermata.
