Aminoacyl tRNA synthetase is an enzyme that attaches the appropriate amino acid to its corresponding tRNA molecule. It plays a crucial role in translating mRNA codons into functional proteins by ensuring the correct amino acids are incorporated.
5 Must Know Facts For Your Next Test
Each aminoacyl tRNA synthetase is specific to one amino acid and its corresponding tRNAs.
There are 20 different aminoacyl tRNA synthetases, one for each of the 20 standard amino acids.
The enzyme uses ATP to activate the amino acid before transferring it to the tRNA.
Accuracy of protein synthesis largely depends on the fidelity of aminoacyl tRNA synthetases.
Mutations in genes encoding these enzymes can lead to serious cellular dysfunctions and diseases.
