abstract = {Fidelity of transfer ribonucleic acid (tRNA) charging by amino acids ensures correct translation of the genetic code into proteins. Charging is catalysed by a set of enzymes known as aminoacyl-tRNA synthetases. Owing to the degeneracy of the genetic code, some of the different tRNAs have the same amino acid attached to them. Specificity of the charging reaction is ensured by positive elements, the identity determinants unique to each tRNA and responsible for its recognition by the cognate synthetase, and negative elements, the antideterminants that prevent false recognitions. To fulfil the aminoacylation specificity and prevent noncognate aminoacyl-tRNA delivery to the ribosome, some synthetases also mediate proofreading reactions that increase fidelity of the tRNA charging. In such reactions, misactivated amino acids or mischarged tRNAs are checked in specific sites and noncognate products are hydrolysed.},
