Chains	Accession	Name	Description	Comments	Source
A	PF19269	Anticodon binding domain (Anticodon_2)	Anticodon binding domain	This entry represents the anticodon binding domain found at the C-terminus of the class-I glutamyl tRNA synthetase enzyme.	Domain
A	PF00749	tRNA synthetases class I (E and Q), catalytic domain (tRNA-synt_1c)	tRNA synthetases class I (E and Q), catalytic domain	Other tRNA synthetase sub-families are too dissimilar to be included. This family includes only glutamyl and glutaminyl tRNA synthetases. In some organisms, a single glutamyl-tRNA synthetase aminoacylates both tRNA(Glu) and tRNA(Gln).	Domain
