  • Publication number: 20230151393
    Abstract: Described herein are the nucleic acid and the amino acid sequences of a cytochrome P450 capable of oxidizing terpene molecules. Also described herein are methods of oxidizing terpene molecules including contacting the cytochrome P450 with the terpene molecule intended to be oxidized. In particular, the method may be carried out in vitro or in vivo to produce oxidized terpene molecules, which may be used in different technical fields such as for example perfumery and flavoring. Also described herein is an expression vector containing the nucleic acid. A non-human host organism or a cell transformed with the nucleic acid is also an object of the disclosure.

  • Patent number: 11293040
    Abstract: Provided is a method of producing one or more sesquiterpene compounds comprising: contacting an acyclic FPP precursor with a polypeptide having terpene synthase activity, wherein the polypeptide comprises an amino acid sequence that has at least 55% sequence identity to SEQ ID NO: 1, to produce one or more terpenes selected from the group consisting of isovalencene, spirovetiva-1(10),7(11)-diene and valencene or derivatives thereof, or mixture of sesquiterpenes comprising one or more of isovalencene, spirovetiva-1(10),7(11)-diene and/or valencene; and optionally isolating the one or more terpenes or the mixture.

  • Patent number: 11214775
    Abstract: Provided herein are biocatalytic methods of producing terpene compounds by applying a novel type of phosphatase enzyme. The method allows the fully biochemical synthesis of terpene compounds, like for example copalol and labdendiol, and derivatives thereof, which serve as valuable intermediates for the production of perfumery ingredients, such as, for example, ambrox. Also provided are novel fully biochemical multistep processes for the production of such compounds as well as novel phosphatase enzymes and mutants and variants derived therefrom.

  • Publication number: 20210010035
    Abstract: Described herein are methods of producing (+)-manool, the methods including: contacting geranylgeranyl diphosphate with a copalyl diphosphate (CPP) synthase to form a (9S, 10S)-copalyl diphosphate and contacting the CPP with a sclareol synthase enzyme to form (+)-manool and derivatives thereof. Also described herein are nucleic acids encoding CPP synthases and sclareol synthases for use in the methods. Further described herein are expression vectors and non-human host organisms and cells including nucleic acids encoding a CPP synthase and a sclareol synthase as described herein.
