Codon-Anticodon Interaction

Di: Everly

An intriguing aspect of codon recognition is “wobble,” occurring at the third nucleotide position of the codon-anticodon interaction. This flexibility allows certain tRNA

Control of translation efficiency in yeast by codon–anticodon interactions

Four-base codon-anticodon interactions: As a codon alternative, Sisido’s team developed a four-base codon system, instead of the natural three-base codon system (type C

Here the authors introduce non-standard nucleotides in bacterial and eukaryotic mRNA to reveal the minimal hydrogen bond requirement of codon-anticodon interaction for efficient and accurate

In this work, on the basis of the available data, we propose that the correct codon:anticodon duplexes are those whose formation and interaction with the ribosomal

The rate at which a codon is read appears not to be constant but depends on the identity of the codon’s neighbours, a phenomenon known as the context effect (for reviews, see

This was shown for a tetraloop hairpin model of the codon-anticodon interaction in tRNA(Tyr) which contains a psi at position 35. Pseudouridine also stabilizes double-stranded RNA when

In particular, nucleosides A1492, A1493 and G530 proofread the codon–anticodon interaction by producing eight hydrogen bonds to both the codon and anticodon backbones in

Accuracy mechanism of eukaryotic ribosome translocation

Imposing a minimum principle in the framework of the so-called crystal basis model of the genetic code, we determine the structure of the minimum set of anticodons which allows

In particular, modifications in the anticodon stem-loop (ASL), located near the site of tRNA:mRNA interaction, can play key roles in ensuring protein homeostasis and accurate translation.

Specifically, it addresses the variability allowed at the third position of the codon-anticodon interaction. Key Points of the Wobble Hypothesis. Base Pairing at the Third Codon

Recently, we have proposed a minimum principle for the codon–anticodon interaction (Sciarrino and Sorba, 2012), in the framework of the so called “crystal basis model”

Now let’s a molecular model of the interaction between this anticodon (m G-A-A on tRNA) with an UUU codon (on mRNA). To better differentiate them, the carbon atoms in tRNA and in mRNA

The formation of a correct codon-anticodon pair is essential to ensure efficiency and fidelity during translation. Here we review the influence that codon-anticodon interactions play

Codon-anticodon Interaction The interaction between codons and anticodons is central to the process of protein synthesis. This interaction ensures that the correct amino acid is added to the growing polypeptide chain in response to

Codon-anticodon interaction

The stronger interaction at the codon–anticodon interface resulted in improved UAG decoding efficiency and a higher yield of the modified protein containing a non-natural amino acid at multiple sites. Our findings are

This codon (mRNA)-anticodon (tRNA) interaction uniquely determines the position of amino acids in proteins. Thus, faithful protein synthesis relies primarily on the accuracy of

The formation of a correct codon–anticodon pair is essential to ensure efficiency and fidelity during translation. Here we review the influence that codon–anticodon interactions play

codon–anticodon interaction has not yet been systematically addressed. By specific insertions of various non-natural mod-ifications into mRNA codons (Fig. 1), we intended to define the

Position 37 modifications stabilize codon:anticodon interactions. Nucleotides at position 37 of tRNAs are adjacent to the 3’ of the anticodon sequence, and not directly involved

Analysis of codon:anticodon interactions within the ribosome provides new insights into codon reading and the genetic code structure. Although the decoding rules have been largely
