Function
[BPPS_SALOF] Catalyzes the formation of the (+)-camphor precursor (+)-bornyl diphosphate from geranyl diphosphate. The enzyme also produces significant amounts of (+)-alpha-pinene, (+)-camphene, and (+-)-limonene.[1]

Publication Abstract from PubMed
The x-ray crystal structure of dimeric (+)-bornyl diphosphate synthase, a metal-requiring monoterpene cyclase from Salvia officinalis, is reported at 2.0-A resolution. Each monomer contains two alpha-helical domains: the C-terminal domain catalyzes the cyclization of geranyl diphosphate, orienting and stabilizing multiple reactive carbocation intermediates; the N-terminal domain has no clearly defined function, although its N terminus caps the active site in the C-terminal domain during catalysis. Structures of complexes with aza analogues of substrate and carbocation intermediates, as well as complexes with pyrophosphate and bornyl diphosphate, provide "snapshots" of the terpene cyclization cascade.
