Killer plasmids as drivers of genetic code changes during yeast evolution
The genetic code was established at a very early stage during the evolution of life on Earth and is nearly universal. In eukaryotic nuclear genes, the only known examples of a sense codon that underwent an evolutionary change of meaning, from one amino acid to another, occur in yeast species. The codon CUG is translated as Leu in the universal genetic code, but it has long been known to be translated as Ser in some Candida species. In recent work, we discovered that this switch is one of three parallel reassignments of CUG that occurred in three closely related clades of yeasts. CUG was reassigned once from Leu to Ala, and twice from Leu to Ser, in three separate events. The meaning of…
