Functioni

Catalyzes the hydrolysis of N-formyl-L-kynurenine to L-kynurenine, the second step in the kynurenine pathway of tryptophan degradation.UniRule annotation

Catalytic activityi

N-formyl-L-kynurenine + H2O = formate + L-kynurenine.UniRule annotation

Pathwayi: L-tryptophan degradation via kynurenine pathway

This protein is involved in step 2 of the subpathway that synthesizes L-kynurenine from L-tryptophan.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Tryptophan 2,3-dioxygenase (kynA), Tryptophan 2,3-dioxygenase (kynA), Tryptophan 2,3-dioxygenase (kynA), Tryptophan 2,3-dioxygenase (kynA)
  2. Kynurenine formamidase (kynB), Kynurenine formamidase (kynB), Kynurenine formamidase (kynB)
This subpathway is part of the pathway L-tryptophan degradation via kynurenine pathway, which is itself part of Amino-acid degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-kynurenine from L-tryptophan, the pathway L-tryptophan degradation via kynurenine pathway and in Amino-acid degradation.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
