Abstact

The crystal structures of cattleyene synthase (apo-CyS), and CyS complexed with geranylgeranyl pyrophosphate (GGPP) were solved. The CySC59A variant exhibited an increased production of cattleyene and other diterpenes with diverse skeletons. Its structure showed a widened active site cavity explaining the relaxed selectivity. Isotopic labeling experiments revealed a remarkable cyclization mechanism involving several skeletal rearrangements for one of the novel diterpenes.
