CC -!- FUNCTION: Catalyzes the hydroxylation of L-kynurenine (L-Kyn) to form
CC 3-hydroxy-L-kynurenine (L-3OHKyn). Required for synthesis of quinolinic
CC acid, a neurotoxic NMDA receptor antagonist and potential endogenous
CC inhibitor of NMDA receptor signaling in axonal targeting,
CC synaptogenesis and apoptosis during brain development. Quinolinic acid
CC may also affect NMDA receptor signaling in pancreatic beta cells,
CC osteoblasts, myocardial cells, and the gastrointestinal tract.
CC {ECO:0000256|HAMAP-Rule:MF_03018}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + L-kynurenine + NADPH + O2 = 3-hydroxy-L-kynurenine +
CC H2O + NADP(+); Xref=Rhea:RHEA:20545, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:57783,

CC ECO:0000256|HAMAP-Rule:MF_03018};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000256|ARBA:ARBA00001974,
CC ECO:0000256|HAMAP-Rule:MF_03018};
CC -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from
CC L-kynurenine: step 1/3. {ECO:0000256|HAMAP-Rule:MF_03018}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane {ECO:0000256|HAMAP-
CC Rule:MF_03018}; Multi-pass membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_03018}.
CC -!- SIMILARITY: Belongs to the aromatic-ring hydroxylase family. KMO
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_03018}.
