Class of enzymes
From Wikipedia, the free encyclopedia
1,8-Cineole synthase (EC 4.2.3.108, 1,8-cineole cyclase, geranyl pyrophoshate:1,8-cineole cyclase, 1,8-cineole synthetase) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase (cyclizing, 1,8-cineole-forming).[1][2][3][4][5] This enzyme catalyses the following chemical reaction
- geranyl diphosphate + H2O 1,8-cineole + diphosphate

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.[6]
