| PF01425 | Amidase (Amidase) | Amidase | This entry represents the amidase signature domain that consists structurally of a core domain that is covered by alpha-helices. In most members, this is found as a standalone domain, while in others, such as Scytalone dehydratase-like protein Arp1, ... | Domain | |
| PF02637 | GatB domain (GatB_Yqey) | GatB domain | This domain is found in GatB. It is about 140 amino acid residues long. This domain is found at the C terminus of GatB Swiss:O30509 which transamidates Glu-tRNA to Gln-tRNA. | Domain | |
| PF02934 | GatB/GatE catalytic domain (GatB_N) | GatB/GatE catalytic domain | This domain is found in the GatB and GatE proteins [1]. | Domain | |
| 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 | |
| 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 | |
