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.

Uniprot ID:
Q16719
Molecular weight:
34634.47
Reactions
L-Kynurenine + Water → 2-Aminobenzoic acid + L-Alaninedetails
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).
