Archaea-specific editing domain of threonyl-tRNA synthetase, with marked structural similarity to D-amino acids deacylases found in eubacteria and eukaryotes. This domain can bind D-amino acids, and ensures high fidelity during translation. It is especially responsible for removing incorrectly attached serine from tRNA-Thr. The domain forms a fold that can be be defined as two layers of beta-sheets (a three-stranded sheet and a five-stranded sheet), with two alpha-helices located adjacent to the five-stranded sheet [1].
