Protein

Kynureninase

Gene

kynU

Organism
Bacillus anthracis
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

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.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
