Protein existenceInferred from homology

General annotation (Comments)

Function

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 By similarity.

Catalytic activity

L-kynurenine + H2O = anthranilate + L-alanine.

L-3-hydroxykynurenine + H2O = 3-hydroxyanthranilate + L-alanine.

Cofactor

Pyridoxal phosphate By similarity.

Pathway

Amino-acid degradation; L-kynurenine degradation; L-alanine and anthranilate from L-kynurenine: step 1/1.

Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from L-kynurenine: step 2/3.

Subunit structure

Homodimer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the kynureninase family.
