Abstract
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. Extensive isotopic labelling experiments were performed to distinguish between various possible cyclization mechanisms of the terpene cyclase and to decipher the EI-MS fragmentation mechanism for pristinol.Entities:
