Widespread position-specific conservation of synonymous rare codons within coding sequences
Synonymous rare codons are considered to be sub-optimal for gene expression because they are translated more slowly than common codons. Yet surprisingly, many protein coding sequences include large clusters of synonymous rare codons. Rare codons at the 5' terminus of coding sequences have been shown to increase translational efficiency. Although a general functional role for synonymous rare cod...
متن کاملNon-random arrangement of synonymous codons in archaea coding sequences.
Non-random arrangement of synonymous codons in coding sequences has been recently reported in eukaryotic and bacterial genomes, but the case in archaeal genomes is largely undetermined. Here, we systematically investigated 122 archaeal genomes for their synonymous codon co-occurrence patterns. We found that in most archaeal coding sequences, the order of synonymous codons is not arranged random...
متن کاملControl of ribosome traffic by position-dependent choice of synonymous codons.
Messenger RNA (mRNA) encodes a sequence of amino acids by using codons. For most amino acids, there are multiple synonymous codons that can encode the amino acid. The translation speed can vary from one codon to another, thus there is room for changing the ribosome speed while keeping the amino acid sequence and hence the resulting protein. Recently, it has been noticed that the choice of the s...
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 کاملRare Codons Cluster
Most amino acids are encoded by more than one codon. These synonymous codons are not used with equal frequency: in every organism, some codons are used more commonly, while others are more rare. Though the encoded protein sequence is identical, selective pressures favor more common codons for enhanced translation speed and fidelity. However, rare codons persist, presumably due to neutral drift....
