CC -!- FUNCTION: Catalyzes the cleavage of L-kynurenine (L-Kyn) and L-3-
CC hydroxykynurenine (L-3OHKyn) into anthranilic acid (AA) and 3-
CC hydroxyanthranilic acid (3-OHAA), respectively. {ECO:0000255|HAMAP-
CC Rule:MF_03017}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + L-kynurenine = anthranilate + H(+) + L-alanine;
CC Xref=Rhea:RHEA:16813, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16567, ChEBI:CHEBI:57959, ChEBI:CHEBI:57972; EC=3.7.1.3;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03017};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-hydroxy-L-kynurenine + H2O = 3-hydroxyanthranilate + H(+) +
CC L-alanine; Xref=Rhea:RHEA:25143, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:36559, ChEBI:CHEBI:57972,
CC ChEBI:CHEBI:58125; EC=3.7.1.3; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_03017};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03017};
CC -!- PATHWAY: Amino-acid degradation; L-kynurenine degradation; L-alanine
CC and anthranilate from L-kynurenine: step 1/1. {ECO:0000255|HAMAP-
CC Rule:MF_03017}.
CC -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from
CC L-kynurenine: step 2/3. {ECO:0000255|HAMAP-Rule:MF_03017}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_03017}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03017}.
CC -!- SIMILARITY: Belongs to the kynureninase family. {ECO:0000255|HAMAP-
CC Rule:MF_03017}.
