The cyclization of glutamine to yield an L-glutamimide residue at the C-terminus of an excised intein during protein splicing. The chemical reactions and pathways involving amino acids, organic acids containing one or more amino substituents. The coupled methyl esterification and deamidation of peptidyl-glutamine. The chemical reactions and pathways resulting in the breakdown of glutamine, 2-amino-4-carbamoylbutanoic acid. The pathway by which ammonia is processed and incorporated into a cell. In an energy-rich (glucose-containing), nitrogen-poor environment glutamine synthetase and glutamate synthase form an ammonia assimilatory cycle, in which ammonia is incorporated into L-glutamate to form L-glutamine, which then combines with alpha-ketoglutarate to regenerate L-glutamate. This ATP-dependent cycle is essential for nitrogen-limited growth and for steady-state growth with some sources of nitrogen. The chemical reactions and pathways involving D-glutamine, the D-enantiomer of the amino acid glutamine, i.e. (2R)-2,5-diamino-5-oxopentanoic acid. The chemical reactions and pathways involving amino acids of the glutamine family, comprising arginine, glutamate, glutamine and proline. The chemical reactions and pathways resulting in the formation of glutamine, 2-amino-4-carbamoylbutanoic acid. The chemical reactions and pathways involving glutamine, 2-amino-4-carbamoylbutanoic acid.
