Protein attributes
| Sequence length | 539 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 | 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. |
