PF01409tRNA 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
PF03483B3/4 domain (B3_4)B3/4 domainThis domain is found in tRNA synthetase beta subunits as well as in some non tRNA synthetase proteins.Domain
