Metabolite Identification
Common NameN'-Formylkynurenine
DescriptionN'-Formylkynurenine belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. N'-Formylkynurenine is a very strong basic compound (based on its pKa). N'-Formylkynurenine exists in all eukaryotes, ranging from yeast to humans. Within humans, n'-formylkynurenine participates in a number of enzymatic reactions. In particular, n'-formylkynurenine can be biosynthesized from L-tryptophan through the action of the enzyme tryptophan 2,3-dioxygenase. In addition, n'-formylkynurenine can be converted into formylanthranilic acid and L-alanine; which is catalyzed by the enzyme kynureninase. The formation of N′-formylkynurenine is catalyzed by heme dioxygenases. In humans, n'-formylkynurenine is involved in tryptophan metabolism. It is a formylated derivative of kynurenine. N′-Formylkynurenine is an intermediate in the catabolism of tryptophan.

Enzymes

General function:
Involved in metabolic process
Specific function:
Catalyzes the cleavage of L-kynurenine (L-Kyn) and L-3-hydroxykynurenine (L-3OHKyn) into anthranilic acid (AA) and 3-hydroxyanthranilic acid (3-OHAA), respectively. Has a preference for the L-3-hydroxy form. Also has cysteine-conjugate-beta-lyase activity.
Gene Name:
KYNU
Uniprot ID:
Q16719
Molecular weight:
34634.47
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
Reactions
D-Tryptophan + Oxygen → N'-Formylkynureninedetails
General function:
Involved in hydrolase activity
Specific function:
Catalyzes the hydrolysis of N-formyl-L-kynurenine to L-kynurenine, the second step in the kynurenine pathway of tryptophan degradation. Kynurenine may be further oxidized to nicotinic acid, NAD(H) and NADP(H). Required for elimination of toxic metabolites (By similarity).

General function:
Involved in heme binding
Specific function:
Catalyzes the first and rate-limiting step in the kynurenine pathway of tryptophan catabolism.
