Accepted name: (+)-bornyl diphosphate synthase
Reaction: geranyl diphosphate = (+)-bornyl diphosphate
For diagram of bornane and related monoterpenoids, click here
Glossary: (+)-bornyl diphosphate = (1R,2S,4R)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl diphosphate
Other name(s): bornyl pyrophosphate synthase (ambiguous); bornyl pyrophosphate synthetase (ambiguous); (+)-bornylpyrophosphate cyclase; geranyl-diphosphate cyclase (ambiguous); (+)-bornyl-diphosphate lyase (decyclizing)
Systematic name: (+)-bornyl-diphosphate lyase (ring-opening)
Comments: Requires Mg2+. The enzyme from Salvia officinalis (sage) can also use (3R)-linalyl diphosphate or more slowly neryl diphosphate in vitro [3]. The reaction proceeds via isomeration of geranyl diphosphate to (3R)-linalyl diphosphate. The oxygen and phosphorus originally linked to C-1 of geranyl diphosphate end up linked to C-2 of (+)-bornyl diphosphate [3]. cf. EC [(–)-bornyl diphosphate synthase].
