1,8-cineole synthase
1,8-Cineole synthase is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase . This enzyme catalyses the following chemical reaction
This enzyme requires Mn2+ or Zn2+. Geranyl diphosphate first isomerizes to (S)-linalyl diphosphate which ionises to the alpha-terpinyl cation which reacts with water to form the product.
