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. Activation of an amino acid for incorporation into a peptide by a nonribosomal process, catalyzed by subunits of nonribosomal peptide synthase. The amino acid is adenylated at its carboxylate group (ATP-dependent) then transferred to the thiol group of an enzyme-bound phosphopantetheine cofactor. Activation of an amino acid for incorporation into a peptide by a nonribosomal process. The chemical reactions and pathways resulting in the formation of peptides, compounds of 2 or more (but usually less than 100) amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another. This may include the translation of a precursor protein and its subsequent processing into a functional peptide. The biosynthetic process whereby peptide bond formation occurs in the absence of the translational machinery. Examples include the synthesis of antibiotic peptides, and glutathione. The modification of an amino acid to an active form, for incorporation into a peptide, protein or other macromolecule.
