General annotation (Comments)

Function	Catalyzes the hydrolysis of N-formyl-L-kynurenine to L-kynurenine, the second step in the conversion of tryptophan to nicotinic acid, NAD(H) and NADP(H). Required for elimination of toxic metabolites By similarity.
Catalytic activity	N-formyl-L-kynurenine + H2O = formate + L-kynurenine.
Pathway	Amino-acid degradation; L-tryptophan degradation via kynurenine pathway; L-kynurenine from L-tryptophan: step 2/2.
Subcellular location	Cytoplasm › cytosol By similarity. Nucleus By similarity.
Sequence similarities	Belongs to the AFMID family.
