Protein

Kynureninase

Gene

kynU

Organism
Bacillus cereus (strain B4264)
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the cleavage of L-kynurenine (L-Kyn) and L-3-hydroxykynurenine (L-3OHKyn) into anthranilic acid (AA) and 3-hydroxyanthranilic acid (3-OHAA), respectively.UniRule annotation

Catalytic activityi

L-3-hydroxykynurenine + H2O = 3-hydroxyanthranilate + L-alanine.UniRule annotation
L-kynurenine + H2O = anthranilate + L-alanine.UniRule annotation

Cofactori

pyridoxal 5'-phosphateUniRule annotation

Pathwayi: L-kynurenine degradation

This protein is involved in step 1 of the subpathway that synthesizes L-alanine and anthranilate from L-kynurenine.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Kynureninase (kynU)
This subpathway is part of the pathway L-kynurenine degradation, which is itself part of Amino-acid degradation.
