We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

-
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.
