The MetRS-N domain binds an Arc1-P domain in a tetrameric complex resembling a classical GST homo-dimer. Domain-swapping between symmetrically related MetRS-N and Arc1p-N domains generates a 2:2 tetramer held together by van der Waals forces. This domain is necessary for formation of the aminoacyl-tRNA synthetase complex necessary for tRNA nuclear export and shuttling as part of the translational apparatus. The domain is associated with Pfam:PF09334.	Domain
B	PF21972	Nuclear-export cofactor Arc1p (Arc1p_N_like)	Nuclear-export cofactor Arc1p	This is the N-terminal domain of nuclear-export cofactor Arc1p (Arc1p-N). Arc1p-N and GluRS-N are known to be necessary and sufficient for formation of the yeast aaRS complex in vivo and in vitro. They are likely to form a stable complex with each ot ...	This is the N-terminal domain of nuclear-export cofactor Arc1p (Arc1p-N). Arc1p-N and GluRS-N are known to be necessary and sufficient for formation of the yeast aaRS complex in vivo and in vitro. They are likely to form a stable complex with each other. Arc1p-N adopts a fold similar to the C-terminal domain of glutathione S-transferase (GST-C).	Domain
