During the process of protein synthesis, the amino acid gets attached to the tRNA with the help of enzyme aminoacyl-tRNA synthetase also called tRNA-ligase. The enzyme attaches the appropriate amino acid to the corresponding tRNA by catalyzing the transesterification reaction between an amino acid with one of the tRNA to form an aminoacyl-tRNA. In humans, there are 20 different aminoacyl-tRNA synthetases are present, one for each amino acid to form 20 different type of aminoacyl-tRNA.
