Metabolite Identification
Common NameL-Asparagine
DescriptionL-Asparagine, also known as Asn or aspartamic acid, belongs to the class of organic compounds known as asparagine and derivatives. Asparagine and derivatives are compounds containing asparagine or a derivative thereof resulting from reaction of asparagine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. L-Asparagine is a drug which is used for nutritional supplementation, also for treating dietary shortage or imbalance. L-Asparagine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. L-Asparagine exists in all living species, ranging from bacteria to humans. L-Asparagine is a potentially toxic compound. L-Asparagine has been found to be associated with several diseases known as pregnancy, cystic fibrosis, gout, and leukemia; also l-asparagine has been linked to the inborn metabolic disorders including celiac disease.

General function:
Amino acid transport and metabolism
Specific function:
Has both L-asparaginase and beta-aspartyl peptidase activity. May be involved in the production of L-aspartate, which can act as an excitatory neurotransmitter in some brain regions. Is highly active with L-Asp beta-methyl ester. Besides, has catalytic activity toward beta-aspartyl dipeptides and their methyl esters, including beta-L-Asp-L-Phe, beta-L-Asp-L-Phe methyl ester (aspartame), beta-L-Asp-L-Ala, beta-L-Asp-L-Leu and beta-L-Asp-L-Lys. Does not have aspartylglucosaminidase activity and is inactive toward GlcNAc-L-Asn. Likewise, has no activity toward glutamine.

General function:
Involved in dolichyl-diphosphooligosaccharide-protein g
Specific function:
Subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation. N-glycosylation occurs cotranslationally and the complex associates with the Sec61 complex at the channel-forming translocon complex that mediates protein translocation across the endoplasmic reticulum (ER). All subunits are required for a maximal enzyme activity.
