ENZYME entry: EC 4.2.3.120
| Accepted Name |
|---|
| (-)-beta-pinene synthase.
|
| Alternative Name(s) |
|---|
| (-)-(1S,5S)-pinene synthase. |
| Beta-geraniolene synthase. |
| Reaction catalysed |
|---|
| Geranyl diphosphate <=> (-)-beta-pinene + diphosphate |
| Comment(s) |
|---|
- Cyclase II of Salvia officinalis (sage) produces about equal parts
(-)-alpha-pinene, (-)-beta-pinene and (-)-camphene, plus traces of
other monoterpenoids.
- The enzyme can also use (3S)-Linalyl diphosphate (preferred to (3R)-
linalyl diphosphate).
- The enzyme from Abies grandis (grand fir) produces roughly equal
parts of (-)-alpha-pinene and (-)-beta-pinene.
- Cyclase IV from Pinus contorta (lodgepole pine) produces 63% (-)-
beta-pinene, 26% 3-carene, and traces of alpha-pinene.
- Synthase III from Pinus taeda (loblolly pine) forms (-)-beta-pinene
with traces of alpha-pinene.
- A cloned enzyme from Artemisia annua (sweet wormwood) gave (-)-beta-
pinene with traces of (-)-alpha-pinene.
- The enzyme from Picea sitchensis (Sika spruce) forms 30% (-)-beta-
pinene and 70% (-)-alpha-pinene.
- See also EC 4.2.3.119, EC 4.2.3.117 and EC 4.2.3.107.
- Formerly EC 4.1.99.8 and EC 4.2.3.14.
