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.
CC       {ECO:0000256|HAMAP-Rule:MF_01970, ECO:0000256|PIRNR:PIRNR038800}.
CC   -!- CATALYTIC ACTIVITY: L-3-hydroxykynurenine + H(2)O = 3-
CC       hydroxyanthranilate + L-alanine. {ECO:0000256|HAMAP-Rule:MF_01970,
CC       ECO:0000256|PIRNR:PIRNR038800}.
CC   -!- CATALYTIC ACTIVITY: L-kynurenine + H(2)O = anthranilate + L-
CC       alanine. {ECO:0000256|HAMAP-Rule:MF_01970,
CC       ECO:0000256|PIRNR:PIRNR038800}.

CC         ECO:0000256|PIRNR:PIRNR038800};
CC   -!- PATHWAY: Amino-acid degradation; L-kynurenine degradation; L-
CC       alanine and anthranilate from L-kynurenine: step 1/1.
CC       {ECO:0000256|HAMAP-Rule:MF_01970, ECO:0000256|PIRNR:PIRNR038800}.
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate
CC       from L-kynurenine: step 2/3. {ECO:0000256|HAMAP-Rule:MF_01970,
CC       ECO:0000256|PIRNR:PIRNR038800}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01970,
CC       ECO:0000256|PIRNR:PIRNR038800}.
CC   -!- SIMILARITY: Belongs to the kynureninase family.
