A	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
A	PF03147	Ferredoxin-fold anticodon binding domain (FDX-ACB)	Ferredoxin-fold anticodon binding domain	This is the anticodon binding domain found in some phenylalanyl tRNA synthetases. The domain has a ferredoxin fold [1,2].	Domain
