Aminoacyl trna synthetase

Aminoacyl-tRNA synthetases (AARSs) perform a pivotal role in translating the genetic code by catalyzing the attachment of the correct amino acid to its cognate tRNA ().The aminoacylation reaction occurs in two steps: the formation of an enzyme-bound aminoacyl-adenylate, followed by transfer of this activated amino acid to either the 2′-or 3′-hydroxy ….

The HTS1 Gene Encodes Both the Cytoplasmic and Mitochondrial Histidine tRNA Synthetases of S. cerevisiae. Cell 1986 ...Aminoacyl-tRNA synthetases (aaRSs) are universally distributed enzymes that catalyze the esterification of a tRNA to its cognate amino acid (i.e., the amino acid corresponding to the anticodon triplet of the tRNA according to the genetic code) ( Ibba and Soll 2000; Pang et al. 2014 ). Pseudouridine is one of the most common RNA modifications; however, only a few mRNA modifiers have been identified to date, and no one mRNA pseudouridine reader is known. Here, we applied a novel genome-wide approach to identify mRNA regions that are bound by yeast methionine aminoacyl tRNA Met synthetase (MetRS).
