Description
The crystal structure of ligand-free tryptophanyl-tRNA synthetase forms a dimer. It contain a conserved core domain that is involved in ATP binding (motif KMSKS, residue 207-211)and hydrolysis and combines with additional domains that determine the specificity of interactions with the tryptophan and tRNA.
