The KYAT1 protein catalyzes the irreversible ammonia action of L-kynurenine to produce kynurenic acid (KA), which is an intermediate in the tryptophan catabolic pathway and a broad-spectrum antagonist of excitatory amino acid receptors. KYAT1 Protein, Human (His) is the recombinant human-derived KYAT1 protein, expressed by E. coli , with C-6*His labeled tag.
