Mass balance status: Balanced.

Enzyme Commission Primary Name: (+)-bornyl diphosphate synthase

Enzyme Commission Synonyms: bornyl pyrophosphate synthase, bornyl pyrophosphate synθse, (+)-bornylpyrophosphate cyclase, geranyl-diphosphate cyclase (ambiguous)

Standard Gibbs Free Energy (ΔrG in kcal/mol): -47.96 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Requires Mg2+. The enzyme from Salvia officinalis (sage) can also use (3R)-linalyl diphosphate or more slowly neryl diphosphate in vitro [Croteau86]. The reaction proceeds via isomeration of geranyl diphosphate to (3R)-linalyl diphosphate. The oxygen and phosphorus directly linked to C-1 of geranyl diphosphate is also linked to C-2 of (+)-bornyl-diphosphate [Croteau86]. cf. EC 5.5.1.f [(-)-bornyl diphosphate synthase].
