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.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.
The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Catalytic activity

Cofactor

pyridoxal 5'-phosphate (UniProtKB | Rhea| CHEBI:597326 )

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.

Features

Showing features for binding site.
