ENZYME entry: EC 4.2.3.121
Accepted Name |
(+)-alpha-pinene synthase.
|
Alternative Name(s) |
(+)-alpha-pinene cyclase. |
Reaction catalysed |
Geranyl diphosphate <=> (+)-alpha-pinene + diphosphate |
Comment(s) |
- Cyclase I of Salvia officinalis (sage) gives about equal parts (+)-
alpha-pinene and (+)-camphene, whereas cyclase III gives about equal
parts of (+)-alpha-pinene and (+)-beta-pinene.
- (3R)-linalyl diphosphate can also be used by the enzyme in preference
to (3S)-linalyl diphosphate.
- The 4-pro-R hydrogen of geranyl diphosphate is lost.
- With synthase II of Pinus taeda (loblolly pine) (+)-beta-pinene was
the only product.
- See also EC 4.2.3.122 and EC 4.2.3.116.
