A Major Controversy in Codon-Anticodon Adaptation Resolved by a New Codon Usage Index
Two alternative hypotheses attribute different benefits to codon-anticodon adaptation. The first assumes that protein production is rate limited by both initiation and elongation and that codon-anticodon adaptation would result in higher elongation efficiency and more efficient and accurate protein production, especially for highly expressed genes. The second claims that protein production is r...
متن کاملRelative Codon Adaptation Index, a Sensitive Measure of Codon Usage Bias
We propose a simple, sensitive measure of synonymous codon usage bias, the Relative Codon Adaptation Index (rCAI), as a way to discriminate better between highly biased and unbiased regions, compared with the widely used Codon Adaptation Index (CAI). CAI is a geometric mean of the relative usage of codons in a gene, and is calculated using the codon usage table trained with a set of highly expr...
متن کاملThe codon Adaptation Index--a measure of directional synonymous codon usage bias, and its potential applications.
A simple, effective measure of synonymous codon usage bias, the Codon Adaptation Index, is detailed. The index uses a reference set of highly expressed genes from a species to assess the relative merits of each codon, and a score for a gene is calculated from the frequency of use of all codons in that gene. The index assesses the extent to which selection has been effective in moulding the patt...
متن کاملCodon adaptation index as a measure of dominating codon bias
UNLABELLED We propose a simple algorithm to detect dominating synonymous codon usage bias in genomes. The algorithm is based on a precise mathematical formulation of the problem that lead us to use the Codon Adaptation Index (CAI) as a 'universal' measure of codon bias. This measure has been previously employed in the specific context of translational bias. With the set of coding sequences as a...
متن کاملP-128: Optimization of Human LH Gene Expression by Codon Usage Adaptation in CHO Cell Line
a:4:{s:10:"Background";s:897:"Human luteinizing hormone (hLH) belongs to glycoprotein hormones which is composed of two non-covalently linked subunit, α and β. The α-subunit is similar in all glycoprotein hormones, whereas the β-subunit is conferring the hormonal specificity. This hormone has important roles in the growth and maturity of sexual organs and secondary sexual characteristics and st...
