"WebAminoacyl-tRNA synthetases play a key role in protein biosynthesis by catalyzing the specific aminoacylation of tRNA at their 3' ends, a two step reaction termed "charging" of tRNA. Class I tRNA synthetases attach an appropriate amino acid to the 2' oxygen of the 3' terminal residue, and class II synthetases attach amino acids at the 3' oxygen. " - Trna synthetase class i
