Structural alignment of human mini-TyrRS with TyrRSs from three bacterial organisms that have known structures. The secondary structure of mini-TyrRS is superimposed on top. Human TyrRS can be aligned with the three bacterial TyrRSs from the N terminus to Ile-324. The alignment was generated by dali (50) and drawn with espript (51). Identical residues are highlighted in red and similarities are shown in pink.
