== Function ==
[https://www.uniprot.org/uniprot/HKT_AEDAE HKT_AEDAE] Catalyzes the pyridoxal 5'-phosphate-dependent transamination of both 3-hydroxykynurenine and L-kynurenine to xanthurenic acid and kynurenic acid, respectively, preferentially using the alpha-ketoacid pyruvate, glyoxylate or oxaloacetate as the amino group acceptor (PubMed:11880382, PubMed:12220660). The affinity and catalytic efficiency for 3-hydroxykynurenine is higher than for L-kynurenine (PubMed:12220660). Involved in the detoxification of cytotoxic metabolite 3-hydroxykynurenine generated by the hydroxylation of L-kynurenine, an intermediate in the tryptophan catabolism pathway (PubMed:11880382, PubMed:12220660). Also catalyzes, although with a lesser efficiency, the transamination of alanine with glyoxylate as an amino group acceptor (PubMed:11880382). May play a role in the detoxification of glyoxylate, a toxic plant metabolite from the diet (Probable).<ref>PMID:11880382</ref> <ref>PMID:12220660</ref> <ref>PMID:11880382</ref> <ref>PMID:12220660</ref>
