Codon substitution in evolution and the "saturation" of synonymous changes.
A mathematical model for codon substitution is presented, taking into account unequal mutation rates among different nucleotides and purifying selection. This model is constructed by using a 61 X 61 transition probability matrix for the 61 nonterminating codons. Under this model, a computer simulation is conducted to study the numbers of silent (synonymous) and amino acid-altering (nonsynonymou...
متن کاملDiscrepancy among the synonymous codons with respect to their selection as optimal codon in bacteria
The different triplets encoding the same amino acid, termed as synonymous codons, are not equally abundant in a genome. Factors such as G + C% and tRNA are known to influence their abundance in a genome. However, the order of the nucleotide in each codon per se might also be another factor impacting on its abundance values. Of the synonymous codons for specific amino acids, some are preferentia...
متن کاملSynonymous Rare Arginine Codons and tRNA Abundance Affect Protein Production and Quality of TEV Protease Variant
It has been identified that a TEV protease (TEVp) variant, TEVp(5M), displays improved solubility. Here, we constructed fifteen TEVp(5M) variants with one or more of six rare arginine codons in the coding sequence replaced with abundant E. coli arginine codons. These codon variants expressed in either E. coli BL21 (DE3) or Rossetta (DE3) showed different solubility and activity. Supply of rare ...
متن کاملSynonymous Codons Direct Cotranslational Folding toward Different Protein Conformations.
In all genomes, most amino acids are encoded by more than one codon. Synonymous codons can modulate protein production and folding, but the mechanism connecting codon usage to protein homeostasis is not known. Here we show that synonymous codon variants in the gene encoding gamma-B crystallin, a mammalian eye-lens protein, modulate the rates of translation and cotranslational folding of protein...
متن کاملSynonymous Codon Substitution Matrices
Observing differences between DNA or protein sequences and estimating the true amount of substitutions from them is a prominent problem in molecular evolution as many analyses are based on distance measures between biological sequences. Since the relationship between the observed and the actual amount of mutations is very complex, more than four decades of research have been spent to improve mo...
