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. |
| CATALYTIC ACTIVITY | Reaction=L-kynurenine + H2O = anthranilate + L-alanine + H(+); Xref=Rhea:RHEA:16813, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:16567, ChEBI:CHEBI:57959, ChEBI:CHEBI:57972; EC=3.7.1.3; |
| CATALYTIC ACTIVITY | Reaction=3-hydroxy-L-kynurenine + H2O = 3-hydroxyanthranilate + L- alanine + H(+); Xref=Rhea:RHEA:25143, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:36559, ChEBI:CHEBI:57972, ChEBI:CHEBI:58125; |
| case <FTTag:PLP> | |
| COFACTOR | Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326; |
| end case | |
| PATHWAY | Amino-acid degradation; L-kynurenine degradation; L-alanine and anthranilate from L-kynurenine: step 1/1. |
| PATHWAY | Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from L-kynurenine: step 2/3. |
| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the kynureninase family. |
