Using microbes to produce different antidepressant brain chemicals made from tryptophan

Microbial cell factories may enable the efficient biosynthesis of tryptophan-derived neuroactive compounds.

• Tryptophan-derived compounds such as serotonin and psilocybin are potential therapeutics for neuropsychiatric disorders.
• Conventional production methods face challenges including low sustainability and high costs.
• Recent advances in synthetic and enzyme engineering have improved the production of these compounds in microbes.
• Key techniques include tryptophan overproduction and the use of specific enzymes for hydroxylation processes.
• Bacterial heme-dependent tryptophan hydroxylases and AI-assisted engineering show promise in enhancing biosynthetic capabilities.
• Current challenges exist in integrating strain design with bioprocess engineering for effective biomanufacturing.
