Function
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
- 3-hydroxy-L-kynurenine + H2O = 3-hydroxyanthranilate + H+ + L-alanine
Cofactor
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.
