Chains	Accession	Name	Description	Comments	Source
A	PF03485	Arginyl tRNA synthetase N terminal domain (Arg_tRNA_synt_N)	Arginyl tRNA synthetase N terminal domain	This domain is found at the amino terminus of Arginyl tRNA synthetase, also called additional domain 1 (Add-1). It is about 140 residues long and it has been suggested that this domain will be involved in tRNA recognition [1].	Domain
A	PF00750	tRNA synthetases class I (R), catalytic domain (tRNA-synt_1d)	tRNA synthetases class I (R), catalytic domain	Other tRNA synthetase sub-families are too dissimilar to be included. This family includes only arginyl tRNA synthetase.	Domain
A	PF05746	DALR anticodon binding domain (DALR_1)	DALR anticodon binding domain	This all alpha helical domain is the anticodon binding domain in Arginyl and glycyl tRNA synthetase. This domain is known as the DALR domain after characteristic conserved amino acids [1].	Domain
