Chains	Accession	Name	Description	Comments	Source
A, C [auth B]	PF19302	Domain of unknown function (DUF5915) (DUF5915)	Domain of unknown function (DUF5915)	This presumed domain is found at the C-terminus of isoleucyl tRNA ligase enzymes.	Domain
A, C [auth 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, C [auth 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
