EC 1.14.14.58     
Accepted name: trimethyltridecatetraene synthase
Reaction: (6E,10E)-geranyllinalool + [reduced NADPH—hemoprotein reductase] + O2 = (3E,7E)-4,8,12-trimethyltrideca-1,3,7,11-tetraene + [oxidized NADPH—hemoprotein reductase] + but-3-en-2-one + 2 H2O

Glossary: (6E,10E)-geranyllinalool = (6E,10E)-3,7,11,15-tetramethylhexadeca-1,6,10,14-tetraen-3-ol
Other name(s): CYP82G1; CYP92C5; CYP92C6; DMNT/TMTT homoterpene synthase
Systematic name: (6E,10E)-geranyllinalool,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase
Comments: A cytochrome P-450 (heme-thiolate) protein isolated from the plants Arabidopsis thaliana (thale cress) and Zea mays (maize). It forms this C16 homoterpene in response to herbivore attack. In vitro some variants of the enzyme also convert (3S,6E)-nerolidol to (3E)-4,8-dimethylnona-1,3,7-triene (see EC 1.14.14.59, dimethylnonatriene synthase).
