Sysname
(2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, cubebol-forming)
Reaction(IUBMB)
(2E,6E)-farnesyl diphosphate + H2O = cubebol + diphosphate [RN:R09891]
Reaction(KEGG)
Substrate
(2E,6E)-farnesyl diphosphate [CPD:C00448];
H2O [CPD:C00001]
Product
cubebol [CPD:C20172];
diphosphate [CPD:C00013]
Comment
Requires Mg2+. The enzyme gives 28% cubebol, 29% (-)-germacrene D, 10% (+)-delta-cadinene and traces of several other sesquiterpenoids. See also EC 4.2.3.75 (-)-germacrene D synthase and EC 4.2.3.13 (+)-delta-cadinene synthase.
