The chemical reactions and pathways involving amino acids, organic acids containing one or more amino substituents. The synthesis of aminoacyl tRNA by the formation of an ester bond between the 3'-hydroxyl group of the most 3' adenosine of the tRNA, to be used in nonribosomal peptide synthesis. The chemical reactions and pathways involving tRNA, transfer RNA, a class of relatively small RNA molecules responsible for mediating the insertion of amino acids into the sequence of nascent polypeptide chains during protein synthesis. Transfer RNA is characterized by the presence of many unusual minor bases, the function of which has not been completely established. A tRNA aminoacylation process in which glutaminyl-tRNAGln is formed by a tRNA-dependent two-step pathway. In the first step a non-discriminating glutamyl-tRNAGlx synthetase generates the misacylated L-glutamyl-tRNAGln species, and in the second step it is amidated to the correctly charged L-glutaminyl-tRNAGln by a glutamyl-tRNAGln amidotransferase. The chemical reactions and pathways involving non-coding RNA transcripts (ncRNAs). The modification of an amino acid to an active form, for incorporation into a peptide, protein or other macromolecule. A tRNA aminoacylation process in which asparaginyl-tRNAAsn is formed by a tRNA-dependent two-step pathway. In the first step a non-discriminating aspartyl-tRNA synthetase generates the misacylated L-aspartyl-tRNAAsn species, and in the second step it is amidated to the correctly charged L-asparaginyl-tRNAAsn by the heterotrimeric aspartyl-tRNAAsn amidotransferase. The chemical reactions and pathways by which the various amino acids become bonded to their corresponding tRNAs. The most common route for synthesis of aminoacyl tRNA is by the formation of an ester bond between the 3'-hydroxyl group of the most 3' adenosine of the tRNA, usually catalyzed by the cognate aminoacyl-tRNA ligase. A given aminoacyl-tRNA ligase aminoacylates all species of an isoaccepting group of tRNA molecules. The synthesis of aminoacyl tRNA by the formation of an ester bond between the 3'-hydroxyl group of the most 3' adenosine of the tRNA, to be used in ribosome-mediated polypeptide synthesis.
