Asparagine

Asparagine is a non-essential amino acid. Its abbreviations are Asn or N, and its codons are AAU or AAC.

It provides an important site for asparagine-linked glycosylation (N-glycosylation) within peptides ^[1][2].

Synthesis

                          (transaminase)                                (asparagine synthase)

Oxaloacetate                   ⇒                        Aspartate                  ⇒                     Asparagine

                 glutamate   →  alpha-ketoglutarate               glutamine  →     glutamate

                                                                                     ATP   →  AMP + PPi
