CC -!- FUNCTION: Catalyzes the hydrolysis of N-formyl-L-kynurenine to L-
CC kynurenine, the second step in the kynurenine pathway of tryptophan
CC degradation. {ECO:0000256|ARBA:ARBA00002204, ECO:0000256|HAMAP-
CC Rule:MF_01969}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N-formyl-L-kynurenine = formate + H(+) + L-kynurenine;
CC Xref=Rhea:RHEA:13009, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15740, ChEBI:CHEBI:57959, ChEBI:CHEBI:58629; EC=3.5.1.9;
CC Evidence={ECO:0000256|ARBA:ARBA00000640, ECO:0000256|HAMAP-
CC Rule:MF_01969};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01969};
CC Note=Binds 2 zinc ions per subunit. {ECO:0000256|HAMAP-Rule:MF_01969};
CC -!- PATHWAY: Amino-acid degradation; L-tryptophan degradation via
CC kynurenine pathway; L-kynurenine from L-tryptophan: step 2/2.
CC {ECO:0000256|HAMAP-Rule:MF_01969}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01969}.
CC -!- SIMILARITY: Belongs to the Cyclase 1 superfamily. KynB family.
CC {ECO:0000256|HAMAP-Rule:MF_01969}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
