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_01970}.
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_01970};
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_01970};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01970};
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_01970}.
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from
CC       L-kynurenine: step 2/3. {ECO:0000255|HAMAP-Rule:MF_01970}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01970}.
CC   -!- SIMILARITY: Belongs to the kynureninase family. {ECO:0000255|HAMAP-
CC       Rule:MF_01970}.
