RT "Living apart together: crosstalk between the core and supernumerary
RT genomes in a fungal plant pathogen.";
RL Submitted (JUN-2016) to the EMBL/GenBank/DDBJ databases.
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: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 ChEBI:CHEBI:57959, ChEBI:CHEBI:58125, ChEBI:CHEBI:58349;
CC EC=1.14.13.9; Evidence={ECO:0000256|ARBA:ARBA00000886,
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}.
CC -!- SIMILARITY: Belongs to the aromatic-ring hydroxylase family. KMO
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_03018}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
