Aminoacyl-tRNA synthetases (AARSs) comprise an enzyme family that generates and maintains pools of aminoacylated tRNAs, which serve as essential substrates for protein synthesis. Many protein synthesis factors, including tRNA and AARSs also have non-canonical functions. Particularly in mammalian cells, alternate functions of AARSs have been associated with re-distribution in the cell to sites that...
Aminoacyl-tRNA synthetases are essential enzymes that help to ensure the fidelity of protein translation by accurately aminoacylating (or “charging”) specific tRNA substrates with cognate amino acids. Many synthetases have an additional catalytic activity to confer amino acid editing or proofreading. This activity relieves ambiguities during translation of the genetic code that result from one synthetase...
The aminoacyl-tRNA synthetases (aaRSs) are a family of enzymes well known for their role in protein synthesis. More recent investigations have discovered that this classic family of enzymes is actually capable of a broad repertoire of functions which not only impact protein synthesis, but extend to a number of other critical cellular activities. Specific aaRSs play roles in cellular fidelity, tRNA...
