Human arylformamidase has the following catalytic activity.


N-formyl-L-kynurenine + H2O →  Formate + L-kynurenine 

Required for elimination of toxic metabolites

It belongs to the AB hydrolase super family.

Even though the structure of the human protein hasn’t been determined, looking at the sequence alignment the catalytic triad residues are conserved. The residues have resisted mutation indicating that they are important for activity.

Our protein is similar to carboxylesterase which also belongs to AB suberfamily.
