What is aminoacylation ? State its significance.

Explanation

During protein synthesis, amino acid reacts with ATP to form amino acid - AMP complex and pyrophosphate. The reaction is catalysed by a specific amino acid-activating enzyme called aminoacyl-t-RNA synthetase in the presence of `Mg^(2+)`. This step is called aminoacylation.
It helps the amino acid to bind to specific site of specific t-RNA. The energy released by change of ATP to AMP is retained for later use.
