Metabolite Identification
Common NameD-Kynurenine
DescriptionD-Kynurenine, which is also known as 3-Anthraniloyl-D-alanine, belongs to the class of compounds known as alkyl-phenylketones. Alkyl-phenylketones are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group.  D-Kynurenine is a metabolite of the amino acid D-tryptophan and can serve as the bioprecursor of kynurenic acid (KYNA) and 3-hydroxykynurenine (PMID: 24158577 ). D-tryptophan can be converted to L-tryptophan by the enzyme D-amino acid oxidase, and it appears that the same enzyme can also produce D-kynurenine from L-kynurenine (PMID: 26661897 ; PMID: 29326945 ). However, the levels of D-tryptophan and D-kynurenine are many times lower than those of the more abundant L-isomers. D-kynurenine has been shown to bind to the arylhydrocarbon receptor (AhR) and to promote the epithelial to mesenchymal transition in cells, which is important for carcinogenesis (PMID: 29442266 ). D-Kynurenine is also an agonist for G protein-coupled receptor, GPR109B which is also known as the hydroxycarboxylic acid receptor 3, or the niacin receptor 2 (PMID: 19237584 ).

Enzymes

General function:
Involved in D-amino-acid oxidase activity
Specific function:
Regulates the level of the neuromodulator D-serine in the brain. Has high activity towards D-DOPA and contributes to dopamine synthesis. Could act as a detoxifying agent which removes D-amino acids accumulated during aging. Acts on a variety of D-amino acids with a preference for those having small hydrophobic side chains followed by those bearing polar, aromatic, and basic groups. Does not act on acidic amino acids.
Gene Name:
DAO
Uniprot ID:
P14920
Molecular weight:
39473.75
General function:
Involved in heme binding
Specific function:
Catalyzes the cleavage of the pyrrol ring of tryptophan and incorporates both atoms of a molecule of oxygen.
Gene Name:
IDO1
Uniprot ID:
P14902
Molecular weight:
45325.89
General function:
Involved in transcription regulator activity
Specific function:
Ligand-activated transcriptional activator. Binds to the XRE promoter region of genes it activates. Activates the expression of multiple phase I and II xenobiotic chemical metabolizing enzyme genes (such as the CYP1A1 gene). Mediates biochemical and toxic effects of halogenated aromatic hydrocarbons. Involved in cell-cycle regulation. Likely to play an important role in the development and maturation of many tissues
Gene Name:
AHR
Uniprot ID:
P35869
Molecular weight:
96146.7
General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
Receptor for 3-OH-octanoid acid mediates a negative feedback regulation of adipocyte lipolysis to counteract prolipolytic influences under conditions of physiological or pathological increases in beta-oxidation rates. Acts as a low affinity receptor for nicotinic acid. This pharmacological effect requires nicotinic acid doses that are much higher than those provided by a normal diet
Gene Name:
GPR109B
Uniprot ID:
P49019
Molecular weight:
44495.0
