A, B	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
