PF00749tRNA synthetases class I (E and Q), catalytic domain (tRNA-synt_1c)tRNA synthetases class I (E and Q), catalytic domainOther 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
