SMART: Pfam domain MetRS-N

MetRS-N

PFAM accession number:	PF09635
Interpro abstract (IPR018285):	This entry represents the N-terminal domain of methionyl-tRNA synthetase (MetRS). This N-terminal appended domain mediates non-catalytic complex formation through its interaction with a domain in the tRNA aminoacylation cofactor Arc1p. The interacting domains of MetRS, GluRS (glutamyl-tRNA synthetase) and Arc1p form a ternary complex resembling a classical GST homo-dimer [ (PUBMED:16914447) ]. 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.
