. "\"The process of coupling proline to prolyl-tRNA, catalyzed by prolyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.\" [GOC:mah, ISBN:0716730510]" . .
