| Accepted name: |
dimethylnonatriene synthase |
| Reaction: |
(3S,6E)-nerolidol + [reduced NADPH—hemoprotein reductase] + O2 = (3E)-4,8-dimethylnona-1,3,7-triene + [oxidized NADPH—hemoprotein reductase] + but-3-en-2-one + 2 H2O |

| Other name(s): |
CYP82G1; CYP92C5; DMNT/TMTT homoterpene synthase |
| Systematic name: |
(3S,6E)-nerolidol,[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 C11 homoterpene in response to herbivore attack. In vitro the enzyme also converts (6E,10E)-geranyllinalool to (3E,7E)-4,8,12-trimethyltrideca-1,3,7,11-tetraene (see EC 1.14.14.58, trimethyltridecatetraene synthase). |
