(+)-Bornyl diphosphate synthase: Complex with Mg and product
Overview
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.
