Protein attributes

Sequence length	416 AA.
Sequence status	Complete.
Protein existence	Inferred 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.
Sequence similarities	Belongs to the kynureninase family.
