CC Evidence={ECO:0000256|PIRNR:PIRNR038800};
CC -!- PATHWAY: Amino-acid degradation; L-kynurenine degradation; L-alanine
CC and anthranilate from L-kynurenine: step 1/1.
CC {ECO:0000256|PIRNR:PIRNR038800}.
CC -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from
CC L-kynurenine: step 2/3. {ECO:0000256|PIRNR:PIRNR038800}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|PIRNR:PIRNR038800}.
CC -!- SIMILARITY: Belongs to the kynureninase family.
CC {ECO:0000256|PIRNR:PIRNR038800}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
