| + | The class II lysyl-tRNA synthetases (KRS) are conserved aminoacyl-tRNA synthetases that attach lysine to the cognate tRNA in a two-step mechanism. The enzyme from the parasitic protozoan Entamoeba histolytica was crystallized in the presence of small ligands to generate snapshots of the lysine-adenylate formation. The residues involved in lysine activation are highly conserved and the active site closes around the lysyl-adenylate, as observed in bacterial KRS. The Entamoeba EMAPII-like polypeptide is not resolved in the crystals, but another Entamoeba-specific insertion could be modeled as a small helix bundle that may contribute to tRNA binding through interaction with the tRNA hinge. | ||
