Abstract

Described herein is a method of producing a drimane sesquiterpene such as albicanol, drimenol and/or derivatives thereof by contacting at least one polypeptide with farnesyl diphosphate (FPP) with a polypeptide comprising a Haloacid dehalogenase (HAD)-like hydrolase domain and having bifunctional terpene synthase activity. The method may be performed in vitro or in vivo. Also described herein are amino acid sequences of polypeptides useful in the methods and nucleic acids encoding the polypeptides described. The described method further provides host cells or organisms genetically modified to express the polypeptides and useful to produce a drimane sesquiterpene such as albicanol, drimenol and/or derivatives thereof.
