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. HAMAP-Rule MF_03017

Catalytic activity

L-kynurenine + H2O = anthranilate + L-alanine. HAMAP-Rule MF_03017

L-3-hydroxykynurenine + H2O = 3-hydroxyanthranilate + L-alanine. HAMAP-Rule MF_03017

Cofactor

Pyridoxal phosphate By similarity. HAMAP-Rule MF_03017

Pathway

Amino-acid degradation; L-kynurenine degradation; L-alanine and anthranilate from L-kynurenine: step 1/1. HAMAP-Rule MF_03017

Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from L-kynurenine: step 2/3. HAMAP-Rule MF_03017

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_03017

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_03017.

Sequence similarities

Belongs to the kynureninase family.
