Kynurenic Acid Synthesis from D-Kynurenine in the Cerebellum: A Distinct Role of D-Amino Acid Oxidase

The enzymatic formation of kynurenic acid (KYNA), a neuromodulator metabolite of the kynurenine pathway (KP) of tryptophan metabolism, in the mammalian brain is widely attributed to kynurenine aminotransferase II (KATII). However, an alternative biosynthetic route, involving the conversion of D-kynu...
