Fig. 1From: Genetic regulation of l-tryptophan metabolism in Psilocybe mexicana supports psilocybin biosynthesisSelected pathways and enzymes of the tryptophan metabolism in P. mexicana. Tryptophan catabolism occurs via the kynurenine pathway, psilocybin biosynthesis and aromatic acetaldehyde synthesis. Indole-3-acetaldehyde was reduced to tryptophol in vitro by adding NaBH4Back to article page
