Classification of aminoacyl-tRNA synthetases. AaRSs are (sub)classified according to the chemical specificity of the reaction they catalyze and on the presence of conserved domains in their amino acid sequences (Class I and II, and subclasses a, b, and c). The aaRS that are associated with the multisynthetase complex (MSC) are connected to the three MSC accessory proteins (p43, p38, and p18) via bold lines
