Comments [?]

case <OC:Vertebrata> or <OC:Fungi>
FUNCTIONCatalyzes the hydrolysis of N-formyl-L-kynurenine to L- kynurenine, the second step in the kynurenine pathway of tryptophan degradation. Kynurenine may be further oxidized to nicotinic acid, NAD(H) and NADP(H). Required for elimination of toxic metabolites.
else
FUNCTIONCatalyzes the hydrolysis of N-formyl-L-kynurenine to L- kynurenine, the second step in the kynurenine pathway of tryptophan degradation. Required for elimination of toxic metabolites.
end case
CATALYTIC ACTIVITY Reaction=H2O + N-formyl-L-kynurenine = formate + H(+) + L-kynurenine; Xref=Rhea:RHEA:13009, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15740, ChEBI:CHEBI:57959, ChEBI:CHEBI:58629; EC=3.5.1.9;
PATHWAYAmino-acid degradation; L-tryptophan degradation via kynurenine pathway; L-kynurenine from L-tryptophan: step 2/2.
case <OC:Mammalia>
SUBCELLULAR LOCATIONCytoplasm, cytosol. Nucleus. Note=Predominantly cytosolic. Some fraction is nuclear.
else case <OC:Vertebrata> and not <OC:Mammalia>
SUBCELLULAR LOCATIONCytoplasm, cytosol. Nucleus.
end case
SUBUNITHomodimer.
case <FTTag:HGGXW>
DOMAINThe main chain amide nitrogen atoms of the second glycine and its adjacent residue in the HGGXW motif define the oxyanion hole, and stabilize the oxyanion that forms during the nucleophilic attack by the catalytic serine during substrate cleavage.
end case
SIMILARITYBelongs to the kynurenine formamidase family.
