Tryptophan decomposition
WebL-Tryptophan decarboxylase ( EC 4.1.1.105) is an enzyme distinguished by the substrate L -tryptophan. [2] [3] This enzyme catalyzes the reaction of L -tryptophan to tryptamine and carbon dioxide. [2] [4] The enzymatic reaction namely takes place in the species Psilocybe cubensi s, where a decarboxylase, kinase, and methyltransferase work ... WebAbstract. In mammalian cells, the essential amino acid tryptophan is degraded primarily by the kynurenine pathway, a cascade of enzymatic steps containing several biologically active compounds. Metabolites of this pathway, collectively termed 'kynurenines', have been shown to be involved in many diverse physiological and pathological processes.
