Chains	Accession	Name	Description	Comments	Source
B	PF08264	Anticodon-binding domain of tRNA ligase (Anticodon_1)	Anticodon-binding domain of tRNA ligase	This domain is found mainly hydrophobic tRNA synthetases. The domain binds to the anticodon of the tRNA ligase.	Domain
B	PF00133	tRNA synthetases class I (I, L, M and V) (tRNA-synt_1)	tRNA synthetases class I (I, L, M and V)	Other tRNA synthetase sub-families are too dissimilar to be included.	Domain
