Function
function
Catalyzes the hydrolysis of N-formyl-L-kynurenine to L-kynurenine, the second step in the kynurenine pathway of tryptophan degradation.
Catalytic activity
- N-formyl-L-kynurenine + H2O = L-kynurenine + formate + H+
Cofactor
Note: Binds 2 zinc ions per subunit.
Pathway
Amino-acid degradation; L-tryptophan degradation via kynurenine pathway; L-kynurenine from L-tryptophan: step 2/2.
