Moonphase 644 Posted July 31, 2018 Share Posted July 31, 2018 Research over the last few decades has suggested that the compound psilocybin may have a number of therapeutic benefits, with potential to help treat anxiety, depression, and even addiction. But until now, the ‘recipe’ for psilocybin has remained a mystery. In a new study, scientists have characterized the four enzymes mushrooms use to make this compound for the first time, setting the stage for pharmaceutical production of the ‘powerful psychedelic fungal drug.’ Scientists have characterized the four enzymes mushrooms use to make psilocybin After identifying and characterizing the enzymes behind psilocybin, the team from Friedrich Schiller University Jena was able to develop the first enzymatic synthesis of the compound, reports C&EN, a publication from the American Chemical Society. To get to the correct ‘recipe,’ the team in the new study sequenced the genomes of two mushroom species. Then, they used engineered bacteria and fungi to confirm gene activity and the order of the synthetic steps, according to C&EN. Their efforts revealed a new enzyme, dubbed PsiD strips carbon dioxide from the tryptophan, while another adds a hydroxyl group – or, oxygen and hydrogen. Another enzyme, known as PsiK acts as a catalyst for phosphotransfer. Then, an enzyme known as PsiM catalyzes the transfer of methyl groups. Based on their discovery, the researchers developed a ‘one-pot reaction’ to create psilocybin from 4-hydroxy-L-tryptophan, using three of the enzymes: PsiD, PsiK, and PsiM. According to the team, the results could now ‘lay the foundation’ for the production of pharmaceutical drugs based on psychedelic mushrooms. 2 Link to post Share on other sites

The chemistry needed to get pure psilocybin now isn't for the average kitchen chemist, and difficult to do. Only problems I see is either it will be extremely hard to get these enzymes, or L-tryptophan will be scheduled as a precursor and you won't be able to get it easily. Or the number of psilocybin overdoses that will follow. Regardless I'll keep my eyes open. 1 Link to post Share on other sites
Moonphase 644 Posted September 30, 2018 Author Share Posted September 30, 2018 Here is something else I found recently that has additional details and better explanation. https://onlinelibrary.wiley.com/doi/full/10.1002/anie.201705489 More details: https://onlinelibrary.wiley.com/action/downloadSupplement?doi=10.1002%2Fanie.201705489&file=anie201705489-sup-0001-misc_information.pdf 1 Link to post Share on other sites
Researcher 13 Posted November 19, 2018 Share Posted November 19, 2018 I hope I did not miss out on this post. What the study above means is not enzymes for all unfortunately, but rather... They have identified those enzymes and used DNA sequencing to locate where on the genome the genes that encode those enzymes are exactly. Nowadays we can cut and paste DNA, and if you now know where to cut you can remove precisely the genes that make these enzymes. Quote The discovery of enzymes that could cut and paste DNA made genetic engineering possible. Restriction enzymes, found naturally in bacteria, can be used to cut DNA fragments at specific sequences, while another enzyme, DNA ligase, can attach or rejoin DNA fragments with complementary ends. So once they have these DNA fragments, they can then insert them into Aspergillus nidulans genome. If you want me to go into more detail on this let me know, I thought I would save you the boredom and leave it out. And then it reproduces and grows in submerged culture while they are feeding it precursors to psilocybin. So unless we get our hands on a genetically modified A. nidulans strain, we are out of luck. Production options for psilocybin – the making of the magic https://www.pubfacts.com/detail/30011099/Production-Options-for-Psilocybin-Making-of-the-Magic Also it has been found that the paper that this thread is about, sequenced the DNA of P.Serbica and called it Cyanescens. Convergent evolution of psilocybin biosynthesis by psychedelic mushrooms Quote Thus we conclude that the genome reported by Fricke et al. as Psilocybe cyanescens is in fact the genome of Psilocybe serbica, and recommend that the relevant database annotations be updated accordingly. https://www.biorxiv.org/content/early/2018/07/25/374199 1 Link to post Share on other sites
