No Evidence that Selection on Synonymous Codon Usage Affects Patterns of Protein Evolution in Bacteria.

Abstract excerpt

Bias in synonymous codon usage has been reported across all kingdoms of life. Evidence suggests that codon usage bias is often driven by selective pressures, typically for translational efficiency. These selective pressures have been shown to depress the rate at which synonymous sites evolve. We hypothesize that selection on synonymous codon use could also slow the rate of protein evolution if a non-synonymous...
