    Molecular Biology by Robert F. Weaver



Activation Site Explanation:

Activation Site is the specific site on an aminoacyl-tRNA synthetase, which activates the amino Acid, resulting in the formation of an aminoacyl adenylate. They aminoacyl-tRNA, also called activating enzymes, catalyze the activation reaction. The first step involves the formation aminoacyl adenylate, from ATP and an amino acid. This activated species is also called an Aminoacyl -AMP.
