Chains	Accession	Name	Description	Comments	Source
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
