摘要: Sesquiterpenoids are very common among natural products. A large number of sesquiterpene synthase genes have been cloned and functionally characterized. However, until now there is no report about the δ-cadinol synthase predominantly forming d-cadinol (syn. torreyol) from farnesyl diphosphate. Sesquiterpenoids boreovibrins structurally similar to δ-cadinol were previously isolated from culture broths of the basidiomycete fungus Boreostereum vibrans. This led us to expect a corresponding gene coding for a δ-cadinol synthase that may be involved in the biosynthesis of boreovibrins in B. vibrans. Here we report the cloning and heterologous expression of a new sesquiterpene synthase gene from B. vibrans. The crude and purified recombinant enzymes, when incubating with farnesyl diphosphate as substrate, gave δ-cadinol as its principal product and thereby identified as a δ-cadinol synthase.
