AaRSsAcidsAcidProteinCell

AaRSs2

• Aminoacyl-tRNA synthetases (aaRSs) are enzymes that join amino acids to tRNAs. (ox.ac.uk)
• All living organisms contain amino-acyl tRNA synthetases (AARSs) ‒ a family of enzymes critical for protein synthesis. (wisconsin.edu)

Acids5

• For mRNA translation at the ribosomes, amino acids are covalently attached ("loaded") onto their respective tRNAs by specific amino-acyl-tRNA synthetases. (bbisolutions.com)
• This group of essential amino acids are identified as the branched-chain amino acids, BCAAs. (drugbank.com)
• Because this arrangement of carbon atoms cannot be made by humans, these amino acids are an essential element in the diet. (drugbank.com)
• The catabolism of all three of these amino acids uses the same enzymes in the first two steps. (drugbank.com)
• Since there is only one dehydrogenase enzyme for all three amino acids, all three a-keto acids accumulate and are excreted in the urine. (drugbank.com)

Acid4

• Alanyl-tRNA synthetase (PL-12) is specific for the amino acid alanine. (bbisolutions.com)
• Leucine is an amino acid commonly found as a component of total parenteral nutrition. (drugbank.com)
• An essential branched-chain amino acid important for hemoglobin formation. (drugbank.com)
• An essential amino acid. (drugbank.com)

Protein1

• Mammalian aminoacyl-tRNA synthetases: cell signaling functions of the protein translation machinery. (ox.ac.uk)

Cell2

• These investigations will undoubtedly provide some of the most fundamental understanding of how and possibly why synthetases became so tightly involved in such a vast array of cell signaling pathways. (ox.ac.uk)
• An organelle is a specialized subunit within a cell that fulfills a specific role or function. (lecturio.com)
