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. {ECO:0000255|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         ChEBI:CHEBI:57959, ChEBI:CHEBI:58125, ChEBI:CHEBI:58349;
CC         EC=1.14.13.9; Evidence={ECO:0000255|HAMAP-Rule:MF_03018};
CC   -!- COFACTOR:
CC       Name=FAD; Xref=ChEBI:CHEBI:57692;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03018};
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from
CC       L-kynurenine: step 1/3. {ECO:0000255|HAMAP-Rule:MF_03018}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane {ECO:0000255|HAMAP-
CC       Rule:MF_03018}.
CC   -!- SIMILARITY: Belongs to the aromatic-ring hydroxylase family. KMO
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_03018}.
