Accession ID Name Pfam Type
PF00749 tRNA synthetases class I (E and Q), catalytic domain 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).
