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. Ref.3 |
| 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. |
| Pathway | Amino-acid degradation; L-kynurenine degradation; L-alanine and anthranilate from L-kynurenine: step 1/1. Ref.3 Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from L-kynurenine: step 2/3. Ref.3 |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | |
| Miscellaneous | Present with 3060 molecules/cell in log phase SD medium. HAMAP-Rule MF_03017 |
| Sequence similarities | Belongs to the kynureninase family. |
