Crystal structure of the editing domain of threonyl-tRNA synthetase from Pyrococcus abyssi


Overview

We report the crystal structure of an archaea-specific editing domain of threonyl-tRNA synthetase that reveals a marked structural similarity to D-amino acid deacylases found in eubacteria and eukaryotes. The domain can bind D-amino acids despite a low sequence identity to other D-amino acid deacylases. These results together indicate the presence of these deacylases in all three kingdoms of life. This underlines an important role they may have played in enforcing homochirality during translation.

About this Structure
