Terpene cyclase

Web16 Aug 2016 · A terpene cyclase from Streptomyces pristinaespiralis was characterized as the synthase for (+)-(2S,3S,9R)-pristinol. The structure of this sesquiterpene alcohol, which has a new carbon skeleton, was established by NMR spectroscopy and single-wavelength anomalous-dispersion X-ray crystallography. Web24 Aug 2024 · Terpene cyclases (TCs), the extraordinary enzymes that create the structural diversity seen in terpene natural products, are traditionally divided into two classes. Although the structural and mechanistic features in class I TCs are well-known, the corresponding details in class II counterparts have not been fully characterized.
