| B [auth A], C [auth B] | PF01409 | tRNA synthetases class II core domain (F) (tRNA-synt_2d) | tRNA synthetases class II core domain (F) | Other tRNA synthetase sub-families are too dissimilar to be included. This family includes only phenylalanyl-tRNA synthetases. This is the core catalytic domain. | Domain |
| B [auth A], C [auth B] | PF18006 | O-phosphoseryl-tRNA synthetase C-terminal domain (SepRS_C) | O-phosphoseryl-tRNA synthetase C-terminal domain | The SSHS domain is mainly found in Archaea. The domain makes up part of the anticodon binding domain at the C-terminal of O-phosphoserine--tRNA(Cys) ligase [1,2]. | Domain |
