Effect of (R)-2-Amino-6-(1R,2S)-1,2-Dihydroxypropyl)-5,6,7,8-Tetrahydropterin-4(3H)-One and Its Structural Analogues on the Temperature Stability of Tryptophan Hydroxylase 2 with the P447R Mutation.

Abstract excerpt

The enzyme tryptophan hydroxylase 2 (TPH2) catalyzes the hydroxylation of L-tryptophan to L-5-hydroxytryptophan (5-HTP), the first and the key step in 5-HT synthesis in the mammalian brain. Mutations in the human Tph2 gene reducing enzyme activity increase the risk of psychopathology. Pharmacological chaperones are small molecules that can specifically bind to mutant protein molecules, restore their disturbed 3D...
