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:0000256|HAMAP-

CC       Rule:MF_03017, ECO:0000256|PIRNR:PIRNR038800}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC       feature annotation. {ECO:0000256|HAMAP-Rule:MF_03017}.
CC   -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC       whole genome shotgun (WGS) entry which is preliminary data.
