Kynurenine 3-monooxygenase (also known as kynurenine 3-hydroxylase) catalyses the hydroxylation of L-kynurenine (L-Kyn) to form 3-hydroxy-L-kynurenine (L-3OHKyn). It has a key role in tryptophan catabolism [PMID: 12974953] and is required for synthesis of quinolinic acid, a neurotoxic NMDA (N-methyl-D-aspartate) receptor antagonist.

The entry also identifies a protein from Drosophila willistoni (B4MPK3) which is a fusion of the kintoun and kynurenine 3-monooxygenase proteins.
