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. Kynurenine may be further oxidized to nicotinic acid,
CC NAD(H) and NADP(H). Required for elimination of toxic metabolites.
CC {ECO:0000255|HAMAP-Rule:MF_03014}.
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:0000255|HAMAP-Rule:MF_03014};
CC -!- PATHWAY: Amino-acid degradation; L-tryptophan degradation via
CC kynurenine pathway; L-kynurenine from L-tryptophan: step 2/2.
CC {ECO:0000255|HAMAP-Rule:MF_03014}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_03014}.
CC -!- DOMAIN: The main chain amide nitrogen atoms of the second glycine and
CC its adjacent residue in the HGGXW motif define the oxyanion hole, and
CC stabilize the oxyanion that forms during the nucleophilic attack by the
CC catalytic serine during substrate cleavage. {ECO:0000255|HAMAP-
CC Rule:MF_03014}.
CC -!- SIMILARITY: Belongs to the kynurenine formamidase family.
CC {ECO:0000255|HAMAP-Rule:MF_03014}.
