EC 4.2.3.144

Accepted name: geranyllinalool synthase

Reaction: geranylgeranyl diphosphate + H2O = (6E,10E)-geranyllinalool + diphosphate

Glossary: geranylgeranyl diphosphate = (2E,6E,10E)-3,7,11,15-tetramethylhexadeca-2,6,10,14-tetraen-1-yl diphosphate
(E,E)-geranyllinalool = (6E,10E)-3,7,11,15-tetramethylhexadeca-1,6,10,14-tetraen-3-ol

Other name(s): TPS04/GES; GES

Systematic name: geranylgeranyl diphosphate diphosphate-lyase ((E,E)-geranyllinalool-forming)

Comments: The enzyme is a component of the herbivore-induced indirect defense system. The product, (E,E)-geranyllinalool, is a precursor to the volatile compound 4,8,12-trimethyl-1,3,7,11-tridecatetraene (TMTT), which is released by many plants in response to damage.
