  • PubMed Abstract: 

    The 20 aminoacyl-tRNA synthetases are divided into two classes, I and II. The 10 class I synthetases are considered to have in common the catalytic domain structure based on the Rossmann fold, which is totally different from the class II catalytic domain structure. The class I synthetases are further divided into three subclasses, a, b and c, according to sequence homology. No conserved structural features for tRNA recognition by class I synthetases have been established.
