专利号:US-2022356497-A1 优先权日:2019-06-26 标 题 :Compositions and methods for synthesis of terpenoids 发明人:DE KOK STEFAN; LAU WARREN; MCSORLEY FERN; MEYER HERMANN-JOSEF; SERBER ZACH; WAWRZYN GRAYSON 权利人:ZYMERGEN INC 摘要:The disclosure relates to the biosynthesis of terpenoids, such as, for example, geraniol and derivatives thereof, using genetic engineering. In particular, the disclosure relates to the biosynthesis of nepetalactol, nepetalactone, dihydronepetalactone, and derivatives thereof. The disclosure provides recombinant cells genetically engineered to produce high levels of nepetalactol, nepetalactone and/or dihydronepetalactone. The disclosure also provides methods of producing nepetalactol, nepetalactone and dihydronepetalactone using cell-based systems as well as cell-free systems.

专利号:US-11427842-B2 优先权日:2018-03-16 标题 :Method and means for manufacturing terpene indole alkaloids 发明人:O'CONNOR SARAH; CAPUTI LORENZO; PAYNE RICHARD; FRANKE JAKOB; FARROW SCOTT 权利人:INNES JOHN CENTRE 摘要:The complex chemistry underlying the extensive transformations involved in terpene indole alkaloid synthesis makes identification of the biosynthetic genes challenging. The present invention relates to methods for producing a terpene indole alkaloid derivative, comprising the steps of: (1) providing a terpene indole alkaloid; and (2) providing a first enzyme termed “Precondylocarpine Acetate Synthaseâ€? (PAS) or a functional variant or homologue thereof; and/or a second enzyme termed “Dehydroprecondylocarpine Acetate Synthaseâ€? (DPAS) or a functional variant or homologue thereof, and optionally providing further identified enzymes involved in this pathway. The invention also encompasses related kits, enzymes, expression vectors, host cells and plants.
