ent-Kaurene, ent-Kauran-16-ol, and Shunted Diterpenoids from an Engineered Strain of Aspergillus oryzae | ChemRxiv
Aspergillus oryzae was engineered to produce high levels of geranylgeranyldiphosphate (GGPP) and ent-kaurene, via ent-copalyl diphosphate, as precursors for future metabolic engineering projects via t...

Pleased to share our full publication of our manuscript describing completion of nicotine biosynthesis in @natcomms.nature.com following our pre-print from December last year. In this work we solve the 200-year-old puzzle of how tobacco plants make nicotine. www.nature.com/articles/s41...

Nicotine biosynthesis is completed by cryptic activating glucosylation - Nature Communications
Despite the significance of nicotine, a neuroactive alkaloid produced by tobacco, its biosynthesis has remained elusive. Here, the authors report the in vitro and in planta reconstruction of a fo...
