Organization of the multiaminoacyl-tRNA synthetase complex and the cotranslational protein folding

Published date : 30 Jun 2015

Aminoacyl-tRNA synthetases (ARSs) play an essential role in the protein synthesis by catalyzing an attachment of their cognate amino acids to tRNAs. Unlike their prokaryotic counterparts, ARSs in higher eukaryotes form a multiaminoacyl-tRNA synthetase complex (MARS), consisting of the subset of ARS polypeptides and three auxiliary proteins. The intriguing feature of MARS complex is the presence of only nine out of twenty ARSs, specific for Arg, Asp, Gln, Glu, Ile, Leu, Lys, Met, and Pro, regardless of the organism, cell, or tissue types.
