Protein attributes

Sequence length	213 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the hydrolysis of N-formyl-L-kynurenine to L-kynurenine 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.
Sequence similarities	Belongs to the kynB family.
Sequence caution	The sequence ABN81891.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
