Aminoacyl tRNA synthetases are enzymes that attach the correct amino acid to its corresponding tRNA molecule during protein synthesis. They play a crucial role in translating genetic information into functional proteins.
5 Must Know Facts For Your Next Test
1. There are 20 different aminoacyl tRNA synthetases, one for each amino acid.
2. These enzymes have two main functions: amino acid activation and transfer of the activated amino acid to tRNA.
3. Each synthetase has a high specificity for both its corresponding amino acid and tRNA.
4. Errors in aminoacyl tRNA synthetase activity can lead to incorrect protein synthesis, potentially causing disease.
5. The binding and recognition process involves an initial formation of an enzyme-amino acid complex followed by the transfer of the amino acid to the tRNA.
