Chains	Accession	Name	Description	Comments	Source
A, B	PF06827	Zinc finger found in FPG and IleRS (zf-FPG_IleRS)	Zinc finger found in FPG and IleRS	This zinc binding domain is found at the C-terminus of isoleucyl tRNA synthetase and the enzyme Formamidopyrimidine-DNA glycosylase EC:3.2.2.23.	Domain
A, 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
A, 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
