Study reveals surprising details of the evolution of protein translation
Date:8/12/2008

amino acids found in proteins) so the researchers looked for clues to their evolutionary histories by comparing their physical and functional traits.

They converted the unique features of the individual tRNA cloverleaf structures into coded characters, a process that allowed a computerized search for the most parsimonious (the simplest, most probable) tRNA family trees for different organismal lineages. In this way they were able to test competing evolutionary hypotheses against the data mined from the structure of the tRNA itself.

"Our findings uniquely focus on structure, the actual aspect of the molecule that encases its function," Caetano-Anolls said.

The analysis indicated that the two functions of the tRNA had different evolutionary histories, Sun said, which suggests that they were acquired at different points in time.

The study predicted that the loading of amino acids on tRNA molecules preceded the refinement of the genetic code into codons, the regions on the messenger RNA that are read by individual tRNAs.

"For the first time, we believe we make this distinction between the evolution of the genetic code (codon discovery) and the evolution of amino acid charging," Sun said.
